Temperature Sensors 205r

Temperature Sensors 205r group 2 are designed to measure the surface temperature of solid bodies in various industries. They have small dimensions, improved thermal inertia characteristics, and do not require complex installation work during mounting on site.

Temperature is the most common parameter for measurement, and overheating is one of the most harmful factors in equipment operation, so there is a huge number of methods and places for using temperature sensors.

The operating principle of resistance temperature detectors 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, a possible linear dependence of resistance on temperature, good reproducibility of properties, and inertness to environmental influences. Platinum best meets all these requirements; copper meets them to a lesser extent.

Thermocouples are exclusively differential temperature sensors. They generate an electrical signal proportional to the temperature difference between two different points. Therefore, the junction (weld) used to measure the desired temperature is called the "hot" junction, and the other unavoidable junction is called the "cold" junction.

Classification of 205r REGMIK Temperature Sensors by Type of Measuring (Sensitive) Element

• Resistance temperature detectors (thermometers) – TSM, TSP;
• Thermoelectric converters (thermocouples) – TXA, TXK, TJK;
• Semiconductor converters – TP.

Main technical characteristics of 205r temperature sensors:

• ME connection scheme – two-, three- or four-wire;
• By type of ME divided into:
  • Resistance temperature detectors (RTDs, thermometers, temperature sensors) (50M, 100M, 50P, 100P, Pt100, Pt500, Pt1000, Pt2000, Pt10000);
  • Thermoelectric converters (TCs, thermocouples, temperature sensors) (TXA (K), TXK (L));
  • Semiconductors (DS18B20);
• Protection degree against dust and water – IP54;
• Design of resistance temperature detectors (temperature sensors) – non-disassemblable;
• Insulation resistance – not less than 100 MOhm;
• Tolerance classes – A, B, C (for RTDs), 1, 2 (for TCs).
