Outdoor window thermometer. Description of installation on plastic and wooden windows

One of the anachronisms that has migrated into the life of modern people is an outdoor thermometer, which, according to established habit, is screwed or glued to the window frame in order to determine the air temperature outside. Why anachronism and why is it not needed? We will try to tell you in the article we bring to your attention. Outdoor thermometers are installed on plastic windows everywhere. In most cases, without even thinking about whether it makes sense to waste time on this useless activity.

But, since such a need exists among a certain category of citizens, we, of course, will answer questions about how best to do this.

window thermometer

In the Natural Sciences section, to the question How to make sure that a thermometer hung outside shows the correct temperature? asked by the author of SoundLive the best answer is Immediately after purchasing a thermometer, you will have a question about the best place to install it. All thermometers can be installed on any side of the window. You should not always be guided by the convenience of installing it on a window or the convenience of taking readings. When installing a thermometer outside a window, you must follow a few simple rules. Place the thermometer away from heat sources and direct sunlight. Heat sources include, for example, vents, ventilation systems, a remote air conditioner unit, etc. All of them will contribute to the microclimate outside the window and can increase the thermometer readings. In the cold season, when the temperature difference indoors and outdoors can reach 40 - 60 °C, infrared radiation from the window and home can increase the thermometer reading by 2 - 4 °C. The sun's rays have a similar effect. Depending on the temperature outside the window, the angle of incidence of the sun's rays, the color of the thermometer, the color of the window frame, etc., the thermometer can heat up to very high temperatures. If the heating temperature of the thermometer on hot sunny days is commensurate with the upper temperature limit on the thermometer scale, this can lead to premature failure of the device. It is recommended to install the thermometer on the north side of the building. This will allow you to get more accurate readings and extend the life of the device (up to several decades). Thermometers for plastic windows are also suitable for use on wooden windows, since they can be installed directly on glass (glazing). It should be noted that the thermometer is an inertial device, and the time to establish its readings is 10 - 20 minutes (depending on the required accuracy). which corresponds to the speed of atmospheric processes. Therefore, you should not expect the thermometer to change its readings immediately as soon as you remove it from the package or install it on a window. Want to know what the near-ideal location for a thermometer looks like? It looks something like this: - A place at a height of about 10 meters from the surface of the earth, away from any buildings and utilities, protected from direct sunlight and rain. It is also desirable that the surface of the earth be in the shade. Since it is impossible to meet all conditions, the readings of outside thermometers will always differ from the readings of professional instruments installed according to all the rules, the readings of which can be seen on TV and in weather forecasts. The thermometer should not be placed on a part of the window that is frequently opened. This will avoid the risk of mechanical destruction of the thermometer.

This is important: the holder is designed for one-time installation of the thermometer. The thermometer holder can be glued not only to glass, but also to the outer plastic of the window

However, the thermometer holder does not adhere reliably to all types of plastic. Therefore, we cannot recommend this installation method to you and recommend installing the thermometer directly on the glass.

Options for installing TSP-N and KTSP-N on pipelines:

Installation type A: For pipelines with a diameter of up to 25 mm, temperature sensors of a special design KTSP-N 6 version (type DS-cable) (TSP-N version 6) with a short immersed part and installed in the corresponding fittings - expanders, which are included in delivery kits for heat meters and flow meters.

Installation type B : In pipelines with a nominal diameter of no more than DN 50 according to GOST R EN 1434-2, installation of temperature sensors in a bend (in an elbow) is also allowed. Temperature sensors on the measuring sections of pipelines can be installed both before and after the flow converters.

Installation type C : If perpendicular (radial installation) of temperature sensors is not possible, then they can be installed obliquely, at an obtuse angle (from 120 to 150 °) to the direction of flow. Moreover, the angles of inclination of the longitudinal axes of the temperature sensors included in the kit to the direction of flow on the supply and return pipelines should differ by no more than three degrees.

Installation type D : For resistance thermometers, perpendicular (radial) installation is the most preferred.

In heat meters, in accordance with the requirements of the Rules for metering thermal energy and coolant on the supply pipeline, resistance thermometers are installed in front of the flow converters, and the distance between them and the flow sensors must be at least 3 DN, and the distance from the resistance thermometers to the nearest local resistance upstream ( including mechanical and magnetic filters) must be at least 5 DN. And if the local resistance is a group of elbows in different planes, a manifold for merging flows, sharp expansions or contractions, or fittings of any type that regulate the flow of the medium, then the distance from such local resistance to the resistance thermometer upstream should be more than 10 D.

To reduce the length of straight sections in front of the temperature sensor after local resistances that cause significant swirling of the flow, flow shapers should be used.

Outdoor thermometer types and installation features

With the onset of cold weather, every person increasingly looks at his thermometer installed outside the window to find out how to dress today when going outside. Often people are faced with the problem of incorrect readings from this device.

This fact occurs due to the fact that when central heating is turned on in apartments, a sharp difference arises between the temperature inside and outside the room. If the difference does not exceed 30 C, then it practically does not affect the readings of the device

This fact can be explained by the fact that the thermometer is located very close to the window. Nevertheless, the street thermometer does not lie, but gives an error.

How to ensure the accuracy of the thermometer readings?

In addition to choosing a good model of outdoor thermometer, it is important to consider some nuances when placing it on a window.

Here are the main ones:

1. The thermometer should be placed in a place where there is no direct sunlight;
2. Another important nuance is protection from wind, rain and other weather conditions;
3. Ice should not freeze on the thermometer in winter, it should not fall into the snow;
4. Avoid contact with metal;
5. For electronic models, it is important to place it as far as possible from the frame.

The surest way to ensure accurate readings from an outdoor thermometer on a window is to place it in a small box that is well ventilated, but protected from the sun and weather conditions.

How to attach an outdoor thermometer to a plastic window

The thermometer is attached to wooden window frames by driving nails through the holes in the thermometer mounting ears or by screwing small screws directly into the window frame. A sticky layer is applied to the legs of thermometers intended for mounting on euro-windows with plastic frames.

To install the thermometer, you need to degrease the areas of the Euro-window frame on which the tabs will be glued, remove the protective film from the Velcro and attach the tabs to the prepared areas. Attaching a thermometer using self-tapping screws to the frame Today, wooden window blocks are being massively replaced with plastic windows, into which it is not recommended to hammer nails, and rarely does anyone dare to attach an outdoor thermometer in this way. If you don’t mind making holes in the Euro-window, you can secure the outdoor thermometer using a self-tapping screw screwed directly into the profile of the plastic window.

Peculiarities

The variety of possibilities for predicting weather and climate changes does not prevent residents of city apartments and private houses from being interested in temperature indicators outside the window. An outdoor thermometer for plastic windows has become as essential an element of everyday life as a convenient ventilation system or mesh on frames. It makes it easy to make decisions about choosing clothes before leaving home, and makes it possible to navigate weather changes without the help of modern gadgets.

A window thermometer for mounting on plastic frames has some differences from its counterparts used in combination with a wooden base.

It uses fasteners to avoid drilling holes in the polymer frame structure.

In addition, thermometers for plastic windows are often attached directly to the surface of the glass unit and have a completely transparent base made of polymer materials.

How to attach an outdoor thermometer to a plastic window

Mosquito net for a plastic window Wash the entire window or only the part that will be installed. After the dirt has been completely washed off and the glass has dried, it is necessary to wipe the glass unit with alcohol or window cleaning liquid.

They will degrease the window and improve adhesion. Cleaning agent for washing windows Remove the paper from the Velcro and install the thermometer, pressing the Velcro tightly to the glass. It is not recommended to glue the thermometer to a plastic profile for two reasons.

Firstly, the glue can leave marks on the profile. Secondly, the distance from the thermometer to the glass unit should be minimal to ensure good visibility of the thermometer readings from the room, especially at night. We remove the film from the thermometer's Velcro. That's all, all that remains is to install the mosquito stack back.

Types of street thermometers

Modern technologies are now making their way into all areas of human life, and even thermometers that are ordinary at first glance have managed to receive several “upgrades”. Let's figure out what kind of street thermometers there are and how they differ.

Liquid thermometers

Perhaps these thermometers are the most common option for windows. Most likely, before replacing the old frames with new plastic ones, this was exactly what hung in your apartment. In appearance and operating principle, such a thermometer is similar to a medical one (mercury):

• on the base (made of plastic or wood) there is a scale with temperature values;
• a glass flask is attached to it, inside of which there is tinted alcohol;
• When heated, the liquid inside the flask expands; when cooled, it decreases in volume.

By changing the level of liquid in the flask, we can find out the current air temperature indoors or outdoors. This type of thermometer has its pros and cons.

Among the advantages of liquid thermometers are:

1. Low cost (from 100 rubles). Moreover, the price will not affect the quality of temperature measurement, but may affect the durability of the device;
2. Inconspicuous and uninteresting for robbers. This item will especially please residents of the first floors;
3. Easy installation - fastening to a plastic window is done using Velcro.

Naturally, such a thermometer cannot boast of an aesthetic appearance. It is not suitable in cases where the window is designed to match the interior of a room or balcony, and any prominent details will spoil its design.

A few more disadvantages of such thermometers:

1. The Velcro of the thermometer loses its properties when re-attached, which can lead to the loss of the thermometer or its breakage if dropped;
2. The low price of the device is often a consequence of the manufacturer’s use of low-quality materials, which is why the thermometer quickly fails;
3. Small divisions and numbers. This becomes a problem for older people or people with poor vision.

In general, this is the most budget-friendly and simplest option for a thermometer for a plastic window. But it will have to be periodically replaced with a new one.

Bimetallic thermometers

Another popular type of outdoor thermometer is bimetallic. It differs from liquid both in structure and principle of operation:

• The temperature scale of a bimetallic thermometer is located in a semicircle;
• the pointer is an arrow that rotates due to the heating or cooling of a metal spring;
• the spring is made of two metals with different temperature coefficients of linear expansion.

The pros and cons of this device are generally similar to the characteristics of an alcohol thermometer. But you can add some of its features:

1. The transparent plastic case does not cover the scale from sunlight, which leads to errors in temperature measurements;
2. The scale has more values ​​than the previous version of the thermometer;
3. The shape and appearance are more interesting and may suit a certain window design.

The mounts for such a thermometer are still the same, and the price of the model depends on their quality and reliability.

Experts note that the temperature measurement error of such thermometers is no more than one degree. This is not a critical value if the thermometer is used for domestic purposes.

Electronic thermometers

A less common type of window thermometer is electronic. Their main feature is their modern appearance and convenient presentation of information.

Operating principle of an electronic thermometer:

• temperature information is displayed on the LCD screen;
• The design is based on two metals with different electronegativity values. When heated or cooled, they affect the change in potential difference, thanks to which we can find out the exact air temperature;
• Such devices operate either from ordinary batteries or from a solar cell.

What kind of thermometer is used for a plastic window?

Which will lead to better results. Also if you use self-tapping screws, we would even recommend using mounting or sealant. This is necessary in order to seal the hole from the self-tapping screw into the frame cavity.

Well, this procedure for installing a thermometer is very simple. We pre-drill holes for screws in the plastic fasteners.

If you don't drill, the plastic will simply crack, trust us. Nothing good will come of this. So don’t be lazy, find the tool and strength to drill holes in the thermometer mounts.

Next, attach the thermometer to the mounting tape. If there is no tape, then do not forget to squeeze out a drop of sealant. Now, screw the screws through the holes in the thermometer mounts.

A street thermometer was simply screwed to wooden windows, but how to properly attach a thermometer to a plastic window? Home :: Questions and answers about repairs :: Plastic windows You shouldn’t damage a plastic window, you don’t need to glue a thermometer to it, or drill it and screw it with screws or self-tapping screws. It is enough to carefully use a knife or a thin screwdriver to lift the sealing rubber that presses the glass, and slip the top of the thermometer under it first, and then the bottom. The elastic band will press it and hold it very securely; no wind will blow it away. And the plastic frame is intact. But this method is for an ordinary thermometer, which used to be nailed to a wooden window with nails (Fig. 1). Now you can buy a special device for plastic windows, with Velcro, the choice is huge (Fig. 2 and 3). This method was taught to me by a master who installed a mosquito net on a window.

And when he couldn’t screw the fasteners, due to inconvenience, he simply glued it with superglue, and said that in general this glue is a very convenient thing when it comes to plastic windows. Then, without hesitation, I glued the thermometer with the remaining glue in the tube, just in the place where the holes for the nails are provided on the thermometer.

But don’t be shy, because the master wasn’t shy at all, and screwed the fasteners to the window with self-tapping screws easily and effortlessly. So such things can be screwed on. I confess to you, if I hadn’t seen how the master did it, I would never have touched the surface of the plastic window frame like this, but he just screwed it on.

When we installed plastic windows, we immediately bought a thermometer, they are already sold with Velcro, so there is nothing complicated there, just like hooks for clothes, they are also sold with Velcro...

To do this, use short-length wood screws. They will firmly and permanently attach the thermometer to the window. When installing an outdoor thermometer on your window, consider the following feature.

In order for it to show the most accurate values ​​possible, it is necessary to place the thermometer in an area that is located away from all kinds of buildings and communications, which is simply impossible to achieve in most cases. If you want to get more accurate readings of the current outside air temperature, it would be advisable to install an electronic thermometer.

This type of device contains electrical sensors in its design, which are more accurate compared to a conventional alcohol thermometer. It often happens that the scale on a regular thermometer is positioned incorrectly, and as a result, the temperature value is overestimated or underestimated.

Comment! Any of the above methods will not withstand an icicle or a large layer of snow falling on the thermometer. Even if the mount itself to the window is strong, the plastic from which the thermometer frame is most often made will crack and the thermometer will fall. Return to contents Installation using rubber seals This installation option is very simple. Its essence is to use a knife to pick up the sealing gum, place the upper “foot” of the thermometer behind it, and then perform similar actions with the lower part. At the same time, you neither spoil the window profile nor stain the double-glazed window.

The safest and simplest methods for fixing the device

There are several ways to attach outdoor thermometers:

• duct tape;
• suckers;
• self-tapping screws;
• brackets.

The most common method is to attach an outdoor thermometer using adhesive tape. If it was not included in the kit, it can be replaced with double-sided tape. Anyone can install the device using tape; this will not require much effort or additional materials, except for any suitable degreasing composition. As the latter, you can use alcohol, turpentine or nail polish remover, as well as any other product designed to degrease the surface.

If there is no adhesive tape on the “holding legs”, then it can be replaced with double-sided tape

To ensure that the thermometer is held securely, the place where it will be attached is treated with a degreaser and wiped dry with a lint-free cloth. The protective film is removed from the adhesive tape, and the thermometer is pressed against the surface with little force. The disadvantage of this method of fastening is its unreliability. If the window sash is opened frequently, the device may fall.

Surface degreasing is an important stage in surface preparation.

If you were unable to attach the thermometer using this method the first time, a knife wrapped in a cloth soaked in solvent will help remove it. In the same way, the adhesive tape should be removed from the device itself and replaced with a new one. After this, you cannot glue the thermometer to the same place. It is better to prudently choose a new position and repeat the same steps.

Attaching the thermometer to adhesive tape

Also, suction cups are not a very reliable way to attach a thermometer to the frame or glass of a window. Most often, electronic thermometers are attached in this way. Suction cups can only be used if the frame cannot be opened at all.

Before installing the thermometer, the surface is also degreased, wiped dry, and only after that the device is installed on it.

However, in strong gusty winds or rain, detachment of the suckers is almost inevitable.

Outdoor thermometers for plastic windows

When using the thermometer, it was necessary to correct the readings and subtract two degrees from the read result. Over time, the outer bulb of the thermometer became covered from the inside with a thin layer of condensation, which made it difficult to read the readings. Due to the leakage of the flask, moisture got inside it, and when the temperature changed, water condensed on the walls. Then the bottom support came unstuck. After a year of operation, the scale and numbers faded, although the thermometer was installed on the north side and the sun's rays did not fall on it. When it became warm, I removed this ill-fated thermometer, opened the flask, removed the moisture, moved the capillary tube down two divisions of the scale and sealed the flask with silicone. I glued the thermometer to its original place using new double-sided tape, taken from the computer wall socket package.

The main errors that occur when installing resistance thermometers:

• The selection for temperature measurement was incorrectly selected (without thermal insulation of the pipeline, leading to increased heat loss).
• The sensor itself is installed incorrectly in the working flow of the medium being measured (small or large mounting length of the sensor; the sensor is not installed along the axis of the flow and not towards the flow).
• A sensor of inappropriate calibration, regulated by the installation diagram of the facility, was installed.
• The requirements for compensation for the influence of changes in ambient temperature have been violated (the sensor is connected to the recording device using a two-wire circuit; the compensation wire and compensation boxes are not used).
• The sensor was incorrectly selected without taking into account the increased vibration, aggressiveness and humidity of the environment and its high pressure.
• Poor contact on the sensor terminal block (bad soldering; nuts are not tightened; in places of high humidity, the wiring is not sealed against moisture getting inside the sensor).

How to choose?

When choosing an outdoor thermometer for double-glazed windows, it is important to focus not only on the design of the device. There are a lot of important points that will have to be taken into account besides this.

• Type of food. Autonomous models (alcohol, bimetallic) do not require external influence throughout their entire service life. It is better to take remote electronic thermometers with solar panels - changing the battery in a fixed device is quite inconvenient. Home models with a remote sensor should be purchased with a rechargeable battery; its energy supply will have to be replenished every 30-40 days.

• Data accuracy. The most reliable information is provided by devices that have been verified at the factory. Their service life, while maintaining data accuracy, varies from 12 to 24 months. Without verification, data distortion in bimetallic and alcohol models can reach 3-5 degrees. Thermal radiation also affects the accuracy of readings from electronic devices, especially if installation rules have been violated.

• Mounting type. Suction cups are the most unreliable option, suitable only for the warm season. When they freeze, they simply stop performing their function, although they look quite presentable and do not leave marks on the surface of the glass unit. Adhesive fastenings are quite strong, but only if the manufacturer himself has not skimped on the composition. For reliability, many consumers additionally use “Moment” type glue, which firmly fixes the thermometer to the glass.

• Life time. For alcohol models, their shelf life is limited by the length of the flask in which the liquid is sealed. Gradually, the volume of its contents decreases, and the thermometer begins to give incorrect readings. On average, it lasts for 5-7 years of successful use. Bimetallic devices lose their relevance after 1-2 years due to mechanical wear of the elements; electronic thermometers are considered the most durable.

• Ease of use. Mechanical and alcohol devices almost never have additional functions. Occasionally you can find a hybrid of a hygrometer and a thermometer. Electronic ones do not have these shortcomings - such a device provides complete control over data on the weather outside and the home microclimate. Needless to say, in terms of convenience they are significantly superior to any analogues.

Taking into account all these points, you can easily select a suitable outdoor thermometer for use in an apartment or private house for installation on a plastic window.

How to calibrate (check) a thermometer at home

If there are doubts about the accuracy of the readings of a thermometer, not necessarily an outdoor one, then the accuracy of its readings can be easily checked at home. There are two methods to calibrate a thermometer: using a thermometer that is known to accurately indicate and using water.

Checking with a reference thermometer

The first method is simple to use; it is enough to place a standard thermometer next to the thermometer being tested, which shows accurately. After at least half an hour, compare the readings. If the thermometers show the same temperature, then everything is in order.
