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

Temperature sensors TSM-204p, TSP-204p, TXA-204p, TXK-204p, TJK-204p of group 2 are designed for measuring the surface temperature of solid objects in various industries. They have small dimensions, improved thermal inertia characteristics, and do not require complex installation work when mounted on-site.

Temperature is the most commonly measured parameter, and overheating is one of the most negative factors in equipment operation, so there are numerous ways and places to use temperature sensors.

The principle of resistance temperature detectors is based on the change in electrical resistance of conductors and semiconductors depending on the 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, good reproducibility of properties, and inertness to environmental influences. Platinum best meets all these requirements; copper 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 used for measuring the required temperature is called the "hot" junction, while the other junction (unavoidable) is called the "cold" junction.
