Temperature sensors TXA-108, TXK-108, TZH-108, TSM-108, MSP-108

Temperature sensors TXA-108, TXK-108, TZH-108, TSM-108, MSP-108 series 1 are designed to measure the temperature of the ambient 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 parameter for measurement, and overheating is one of the most dangerous factors in equipment operation, therefore there are many application options for temperature sensors under various conditions.

The operating principle of resistance temperature detectors is based on the change in electrical resistance of conductors and semiconductors depending on temperature. The manufacturing material of such sensors 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 these requirements; copper somewhat less so.

Thermocouples are exclusively differential temperature sensors. They generate an electrical signal proportional to the temperature difference between two different points. The junction (junction) used for measuring the required temperature is called the "hot" junction, while the other unavoidable junction is called the "cold" junction.
