Air temperature sensors TSP-307 group 3 are designed for measuring the surface temperature of solid bodies in various industries. They have small dimensions, improved thermal inertia characteristics, and do not require complex installation work on site. Temperature is the most commonly measured parameter, and overheating is one of the most harmful factors affecting equipment operation, therefore, there are numerous methods and locations for temperature sensor application. 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 a sensor must have a high temperature coefficient of resistance, preferably a linear dependence of resistance on temperature, good reproducibility of properties, and inertness to environmental influences. Platinum best meets all these requirements; copper somewhat less. Thermocouples are strictly differential temperature sensors. They generate an electrical signal proportional to the temperature difference between two different points. Therefore, the junction used for measuring the required temperature is called the "hot" junction, and the other unavoidable connection point is called the "cold" junction. Classification of air temperature sensors TSP-307 REGMIK by type of measuring (sensitive) element Resistance temperature detectors (thermometers) – TSP; Thermoelectric converters (thermocouples) – TXA, TXK, TJK; Semiconductor converters – TP. Main technical characteristics of TSP-307 temperature sensors: By element type they are divided into: Resistance temperature detectors (RTDs, thermometers, temperature sensors) (Pt100, Pt500, Pt1000, Pt2000, Pt10000); Thermoelectric converters (thermocouples, temperature sensors) (TXA (K), TXK (L), TJK (J)); Semiconductor (DS18B20); Protection level against dust and water – IP0; Construction of RTDs (temperature sensors) – non-disassemblable; Insulation resistance – not less than 100 MΩ; Accuracy classes – A, B, C (for TSP-307), 1, 2 (for TXA-307, TXK-307, TJK-307).
