Temperature sensors TSP-111 TSM-111 TXA-111 TZHK-111 TXK-111

Temperature sensors TSP-111, TSM-111, TXA-111, TZHK-111, and TXK-111 of group 1 are designed to measure the temperature of the surrounding environment, liquid, gaseous, and bulk chemically non-aggressive media, as well as the surface of solid bodies in various industries.

Temperature is the most common measured parameter, and overheating is one of the most significant negative factors in equipment operation, so there are many methods and applications for temperature sensors.

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

Thermocouples are exclusively differential temperature sensors. They generate an electrical signal proportional to the temperature difference between two different points. Therefore, the junction (joint) used to measure the required temperature is called the "hot" junction, while the other junction (which is inevitable) is called the "cold" junction.
