Temperature sensors TSM-204, TSP-204, TXA-204, TXK-204, TJK-204

Temperature sensors TSM-204, TSP-204, TXA-204, TXK-204, TJK-204 of group 2 are designed to measure the temperature of solid surfaces in various industrial sectors. They have small dimensions, improved thermal inertia characteristics, and do not require complex installation work on site.

Temperature is the most common measurable parameter, and overheating is one of the most negative factors in equipment operation, so there is a wide variety of methods and applications for temperature sensors.

The principle of operation of resistance temperature detectors (RTDs) is based on the change in 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, preferably a linear dependence of resistance on temperature, good reproducibility of properties, and inertness to environmental influences. Platinum meets all these requirements best; copper somewhat less so.

Thermocouples are purely differential temperature sensors. They generate an electrical signal proportional to the difference in temperature between two different points. Therefore, the junction where we measure the desired temperature is called the "hot" junction, and the other junction (which cannot be avoided) is called the "cold" junction.
