WZPK Series Armored Temperature Sensor
The armored thermal resistor is a temperature sensor that measures temperature by using the characteristic that the resistance of a material changes as the temperature changes. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.

Detailed introduction
1. Overview
Armored thermal resistor is a temperature sensor that measures temperature by using the characteristic that the resistance of a material changes as the temperature changes. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value. It has a smaller diameter than the assembled platinum resistor and is easy to bend. It is suitable for installation in special occasions such as narrow pipes and those requiring fast response and miniaturization. It can automatically detect gas, liquid media and solid surfaces within the temperature range of -200~600℃, and can be directly connected to the secondary instrument with copper wire. Due to its good electrical output characteristics, it can provide accurate input values for displays, recorders, regulators, scanners, data recorders and computers.
Armored thermal resistors are mainly used for temperature measurement of bearings or cooling systems of large motors, fans and nuclear motors.
Armored thermal resistors are usually composed of temperature sensing elements, protective tube devices and junction boxes.
2. Performance indicators:
a: Temperature measurement range: -40~180℃;
b: Insulation resistance: ≥100MΩ;
c: Thermal response time: The thermal response time varies according to the diameter and material of the protection tube;
d: Withstand voltage: 50Hz 1000V 1min without breakdown flicker
