Air temperature sensors TSM-303p TSP-303p TXA-303p TXK-303p TZHK-303p

Air temperature sensors TSM-303p, TSP-303p, TXA-303p, TXK-303p, TZHK-303p group 3 are designed for measuring air temperature in various industrial sectors. They have small dimensions, improved thermal inertia characteristics, and do not require complex installation work when mounted at the site.

Temperature is the most common measured parameter, and overheating is one of the most negative factors in equipment operation, so there are many methods and places for using temperature sensors.

The operating principle of resistance temperature detectors (air temperature sensors TSM-303p, TSP-303p) is based on the change in electrical resistance of conductors and semiconductors depending on temperature. The material used to manufacture such sensors must have a high temperature coefficient of resistance, preferably a linear dependence of resistance on temperature, reproducibility of properties, and inertness to environmental influences. Platinum best meets all the above properties; copper meets them somewhat less.

Thermocouples (air temperature sensors TXA-303p, TXK-303p, TZHK-303p) are exclusively differential temperature sensors. They generate an electrical signal proportional to the temperature difference between two different points. Therefore, the junction (splice) used to measure the required temperature is called the "hot" junction, and the other unavoidable junction is called the "cold" junction.

Classification of air temperature sensors 303p REGMIK by type of measuring (sensitive) element

• resistance temperature detectors (thermometers) - TSM, TSP;
• thermoelectric transducers (thermocouples) - TXA, TXK, TZHK;
• semiconductor converters - TP.

Main technical characteristics of air temperature sensors TSM-303p, TSP-303p, TXA-303p, TXK-303p, TZHK-303p:
