Power Electronics

Platinum resistance temperature sensors are widely used in precision measurement of instruments and meters, machinery, medical and other fields. The common application temperature range is -200-600 degrees. Its characteristics are simple structure, and the probe part can be bent arbitrarily, which is convenient for occasions requiring bending temperature measurement and high temperature measurement, and easy to install.

Product Description:

The size and appearance of the special PT100 temperature sensor for the wind power industry can be customized.

Industrial thermal resistance is used as a temperature measurement sensor. It is usually used in conjunction with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control the temperature range of -200 ° C to 500 ° C in various production processes. Temperature of liquid, vapor, and gaseous media and solid surfaces.

Thermal resistance measures the temperature of a substance when its temperature changes with its own resistance. When a temperature gradient exists in the measured medium, the measured temperature is the average temperature in the medium where the temperature sensing element is located.
