Temperature sensors 301

Temperature sensors air 301 group 3 are designed to measure air temperature in various industries. Thermal converters of group 3 have minimal indicators of thermal inertia, do not require complex installation work when installed at the facility. They can be used to measure temperature in ventilation ducts, storage facilities, etc.

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 is based on a change in the electrical resistance of conductors and semiconductors depending on temperature. The material from which such a sensor is made should have a high temperature coefficient of resistance, possibly a linear dependence of resistance on temperature, good reproducibility of properties and inertness to environmental influences. To the greatest extent, platinum satisfies all of the above properties; slightly less copper.

Thermocouple Are exclusively differential temperature sensors. They generate 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 (from which we can not escape) is called the "cold" junction.

Classification of 301 REGMIK air temperature sensors by the type of measuring (sensing) element

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

Main technical characteristics of temperature sensors 301:

• 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.
