Temperature sensors TXA-108, TXK-108, TJK-108, TSM-108, TSP-108

Temperature sensors ТХА-108, ТХК-108, ТЖК-108, ТСМ-108, ТСП-108 group 1 are intended for measuring the temperature of the environment, liquid, gaseous and bulk chemically non-aggressive media, as well as the surface of solids in various industries.

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.
