Air temperature sensors ТСМ-303p ТСП-303p ТХА-303p ТХК-303p ТЖК-303p

Temperature sensors TSM-303p, TSP-303p, ТХА-303p, ТХК-303p, ТЖК-303p group 3 air temperature sensors are designed to measure air temperature in various industries. They have small dimensions, improved thermal inertia, do not require complex installation work when installed on site.

Temperature is the most common measured parameter, and overheating is one of the most negative factors in the operation of equipment, therefore, there are a huge number of ways and places of using temperature sensors.

The principle of operation of resistance thermocouples (air temperature sensors TSM-303p, TSP-303p) is based on the change in the electrical resistance of conductors and semiconductors depending on temperature. The material from which such a sensor is made must have a high temperature coefficient of resistance, if possible, a linear dependence of resistance on temperature, good reproducibility of properties, and inertness to environmental influences. To the greatest extent, platinum satisfies all the above properties; in a slightly smaller one - copper.

Thermocouple (Air temperature sensors ТХА-303p, ТХК-303p, ТЖК-303p) are exclusively differential temperature sensors. They form an electrical signal proportional to the temperature difference between two different points. Therefore, the junction (junction) that we use to measure the required temperature is called the "hot" junction, while the other junction (which we can't avoid in any way) is called the "cold" junction.

Classification of air temperature sensors 303p REGMIK according to the type of measuring (sensing) element

• resistance thermocouples (thermometers) - TSM, TSP;
• thermoelectric thermocouples (thermocouples) - THA, THK, TJK;
• semiconductor converters - TP.

Main technical characteristics of air temperature sensors ТСМ-303p, ТСП-303p, ТХА-303p, ТХК-303p, ТЖК-303p:

• Tolerance classes - 1 / 3B, A, B, C (for resistance thermocouples TCM and TSP), 1 and 2 (for thermocouples TXA, TXK, TJK);
• Sensing element (SE) connection diagram - two-, three-, four-wire;
• according to the type of ChE, they are divided into resistance temperature converters (50M, 100M, 50P, 100P, Pt100, Pt500, Pt1000, Pt2000, Pt10000), semiconductor (DS18B20);
• Thermal converters design - non-separable;
• Insulation resistance - not less than 100 megohms.
