Overview
The WZ series industrial thermistor is used as a temperature measurement sensor, usually paired with temperature transmitters, regulators, and display instruments to form a process control system. It is used to directly measure or control the temperature of liquid, steam, gas media, and solid surfaces within the range of -200 ℃ to 500 ℃ in various production processes
Product Details
Characteristics of WZP thermistor:
·Pressure spring type temperature sensing element with good anti vibration performance;
·High temperature measurement accuracy;
·High mechanical strength and good pressure resistance;
·Imported thin film resistor components with reliable and stable performance.
working principle
Thermistor measures temperature by utilizing the characteristic that the resistance of a substance changes with temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.
