Temperature sensor for the boiler: description, characteristics, principle of operation

The management of modern heating systems is a simple process. The main thing in it is to correctly organize the operation of the automation system and to connect the necessary accessories. In order not to have to independently monitor the parameters of the equipment operation and compare them with the current microclimate, manufacturers offer convenient and functional thermostats. A classic solution of this type is the temperature sensor for the boiler, which acts as a kind of informer for automation equipment. With the help of such a device, the heating system adapts itself to the required operating parameters.

General information about the sensor

The sensor itself is rarely seen as an integral part of the heating infrastructure. It is usually included in the basic equipment of thermostats and control relays. Like other spare parts for boilers, like injectors, fittings, burners and adapters for boilers, the sensor is combined with certain types of equipment. Of course, there are universal models, but they are also recommended to initially compare the characteristics with the target operating installations.

Externally, temperature sensors are small devices that can assume different ways of attaching to the surface. In this case, it is desirable to provide and means of providing protection. Especially if an outside temperature sensor is used for the boiler, it is necessary to prepare insulation from moisture, frost and mechanical influences.

Principle of operation

The main task of the sensor is to determine the temperature indexes. Further information is sent to the thermostat board, which already, depending on the user-set program, gives the command to the boiler plant. The temperature is determined either by the traditional principles of expansion and contraction of the active substance, depending on the characteristics of the environment, or on the principle of sensitivity of semiconductors. Most often, the temperature sensor for a gas boiler operates on the principle of electrical resistance, which allows recording the operating readings, but also there are silicon and resistive devices. Actually, from the point of view of household purpose, the principle of determining the temperature regime has no special meaning, since the error of the sensor will still be compensated for by the deviations in the operation of the boiler station in the range 1-2 ° С.

Types of sensors

In addition to separating the sensors by the temperature determination method, there is also a classification according to the type of interaction with the thermostat. In this plan, you can divide your devices into wired and wireless devices. The first option has the advantage of the possibility of a stable transmission of more accurate readings, and wireless models relieve the user from the hassle of laying an additional cable. In addition, the temperature sensor for the boiler is presented on the market in the form of street and room modifications.

It has already been noted that outdoor devices require a more careful approach to protection. For this reason, the developers of sensors for operation outside the home endow them with more durable, wear-resistant and waterproof enclosures. By the way, in itself an external temperature sensor for the boiler is appropriate to use for the reason that it will give the thermostat more complete information about the condition of the microclimate, which will allow more efficient management of the heating system without the owner's participation.

Main characteristics

The main quality that determines the operational capabilities of such sensors is the temperature range. Simple entry-level models usually support a spectrum of 10 to 40 ° C. But to work with productive boiler plants this is not enough. Therefore, a range from -10 to 70 ° C can become a win-win option.

As for the dimensions, room temperature sensors for boilers have a modest size - about 2-3 cm in length and width. Another thing is that multifunction devices with several measuring channels are supplied with additional blocks. Also, the choice should take into account the length of the cable, if it is a wire model. There are several standard sizes. For example, the same room sensors, providing for a close installation relative to the boiler, contain a wire of up to 5 m. Outdoor devices also communicate with boilers with a wire of more than 10 m in length. Wireless models, in turn, are important to acquire, given the possibility of such communication with a thermostat By radio.

Manufacturers

Often, the production of boiler sensors are handled by the developers of heating equipment. Among such companies, we can distinguish "Baxi", "Weismann", "Velliant", etc. To the manufacturers specializing in thermoregulators, the firms "Proterm", "Thermo", "Meibes", etc., are the same. Accessories and spare parts for boilers, including thermostats, hoses, heating elements, as well as automation elements.

Conclusion

The equipment of a modern boiler in a base set many users consider superfluous. It's about a wide range of functions that provide opportunities to produce complex hardware settings. Against this background, it may seem unjustified and the provision of a heating system with another element, for which even a separate line of wiring is required. Anyway, the temperature sensor for the boiler really brings tangible benefits. With its help, the thermostat automation automatically analyzes the information about the local microclimate and, on the basis of its processing, appropriately controls the boiler itself. That is, the participation of a person who can make a mistake in setting up is virtually eliminated. From the user, only the initial determination of the parameters in which the unit is to operate under certain temperature conditions is required.
