Prefabricated thermistor temperature sensors are matched with display instruments to measure the temperature of liquid, gas media, and solid surfaces within the range of -200-600 ℃. They are widely used in industrial sectors and technological fields such as petroleum, chemical, mechanical, metallurgical, power, textile, food, atomic energy, aerospace, etc. Prefabricated thermistors are usually composed of temperature sensing elements, installation and fixing devices, and junction boxes and other main components.

Working principle of assembling thermistor

Thermistor measures temperature by utilizing the characteristic that the resistance of a substance changes with temperature. The heated part (temperature sensing element) of a thermal resistor is uniformly wound around a skeleton made of insulating material with thin metal wires. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the dielectric layer within the range of the temperature sensing element
