Management of modern heating systems is a simple process. The main thing in it is to properly organize the work of automation and connect the necessary accessories. In order not to have to independently monitor the parameters of the equipment and compare them with the current microclimate, manufacturers offer convenient and functional thermostats. The classic solution of this type is a temperature sensor for the boiler, which acts as a kind of informant for equipment automation. With the help of such a device, the heating system independently adjusts to the desired operating parameters.
Sensor overview
The sensor itself is rarely considered as an integral part of the heating infrastructure. Usually it is included in the basic configuration of thermostats and control relays. Like other boiler parts, such as nozzles, fittings, burners and boiler adapters, the sensor is compatible with certain types of equipment. Of course, there are universal models, but it is also recommended that they be initially compared in terms of characteristics with target operating installations.
Externally, temperature sensors aresmall devices that may involve different ways of attaching to the surface. At the same time, it is desirable to provide for means of ensuring protection. Especially if an outside temperature sensor is used for the boiler, insulation against moisture, frost and mechanical stress should be prepared.
Working principle
The main task of the sensor is to determine the temperature readings. Further, the received information is sent to the thermostat board, which, depending on the program configured by the user, gives the command to the boiler installation. The temperature is determined either according to the traditional principles of expansion and contraction of the active substance, depending on the characteristics of the environment, or according to the principle of the sensitivity of semiconductors. Most often, the temperature sensor for a gas boiler works on the principle of electrical resistance, which allows you to register operating readings, but silicon and resistive devices are also found. Actually, from the point of view of household purposes, the principle of determining the temperature regime is of no particular importance, since the sensor error will still be compensated by deviations in the operation of the boiler station in the range of 1-2 ° С.
Types of sensors
In addition to the division of sensors according to the method of determining the temperature, there is also a classification according to the type of interaction with the thermostat. In this regard, devices can be divided into wired and wireless. The first option has the advantage ofthe possibility of stable transmission of more accurate readings, and wireless models save the user from the hassle of laying an additional cable. In addition, the temperature sensor for the boiler is available on the market in the form of outdoor and indoor modifications.
It has already been noted that outdoor devices require a more careful approach to protection. For this reason, manufacturers of sensors for outdoor use endow them with more durable, wear-resistant and moisture-proof housings. By the way, by itself, it is advisable to use an external temperature sensor for the boiler for the reason that it will give the thermostat more complete information about the state of the microclimate, which will allow more efficient control of the heating system without the participation of the owner.
Key Features
The main quality that determines the operational capabilities of such sensors is the temperature range. Simple entry-level models usually support a range of 10 to 40°C. But this is not enough to work with productive boiler plants. Therefore, a range from -10 to 70 ° C can become a win-win option.
As for the size, room temperature sensors for boilers have modest dimensions - about 2-3 cm in length and width. Another thing is that multifunctional devices with several measuring channels are supplied with additional blocks. Also in the choice should take into account the length of the cable, if we are talking about a wired model. There are several standard sizes. For example, the same room sensors,providing for close installation relative to the boiler, they contain a wire up to 5 m in the configuration. Outdoor appliances are connected to boilers with a wire longer than 10 m. Wireless models, in turn, are important to purchase, taking into account the possibility of such a connection with the thermostat via radio.
Producers
Often, the developers of heating equipment themselves are engaged in the production of boiler sensors. Among such companies, Baksi, Weissmann, Welliant, etc. can be distinguished. Manufacturers specializing specifically in temperature controllers include Proterm, Thermo, Meybes, etc. The same manufacturers produce accessories and spare parts for boilers, including thermostats, hoses, heating elements, as well as automation elements.
Conclusion
Equipment of a modern boiler in the basic configuration is considered by many users to be redundant. We are talking about a wide range of functions that provide the possibility of making complex equipment settings. Against this background, it may seem unjustified to provide the heating system with another element, which even requires a separate wiring line. One way or another, the temperature sensor for the boiler really brings tangible benefits. With its help, the automation of the thermostat correctly analyzes information about the local microclimate and, based on its processing, controls the boiler itself in an appropriate way. That is, the participation of a person who can make a mistake in setting up is practically excluded. The user only needsinitial determination of the parameters in which the unit must operate in certain temperature conditions.
