Product Description
Product Overview
JC100 series of industrial thermal resistor, as a temperature measurement sensor, is usually used together with temperature transducer, regulator and display instrument to form a process control system for direct measurement or control of the temperature of liquid, vapor and gas media as well as solid surface within -200ºC ~ 500ºC in various production processes. The thermal resistor measures temperature by using the characteristic that the resistance itself changes with the change of temperature of substance. When temperature gradient exists in the measured medium, the temperature measured is the average temperature of the medium where temperature-sensing element is located. Although the appearance of all thermal resistors varies widely, their basic structure is roughly similar, generally including such major components as temperature-sensing element, insulation casing, protective tube and junction box.
Working Principle
Thermal resistor measures temperature by using the characteristic that the resistance itself changes with the change of temperature of substance. When the resistance changes, the bridge passing through the temperature transducer will produce an unbalanced signal, which is converted into 4-20mA DC signal after being amplified, and then the working instrument will show the corresponding temperature value.
