Overview

Armored thermistors are usually used in conjunction with display instruments, recording instruments, electronic computers, and other devices. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of -200 ℃ to -500 ℃ in various production processes.

Product Details

Armored thermistor is a type of temperature sensor that has a smaller diameter, is more flexible, and has better seismic resistance than prefabricated thermistors. It is suitable for installation in situations where prefabricated thermistors cannot be installed. Our company's WZPK series uses imported thermistors for temperature measurement, which has the advantages of precision, sensitivity, fast thermal response time, stable quality, and long service life. The outer protective cover is made of stainless steel and filled with high-density oxide material insulation, therefore, it has strong anti pollution performance and mechanical strength, suitable for installation in harsh environments. It can be used to measure temperatures within the range of -200 to 600 ℃, and can be directly connected with copper wires and secondary instruments. It has good electrical output characteristics and can provide accurate temperature change signals for display instruments, recorders, regulators, scanners, data recorders, and computers.
WZPK2-475 Armored ThermistorWorking Principle:
Working principle of armored thermistor: Under the action of temperature, the resistance of the thermistor wire changes accordingly, and the display instrument will indicate the temperature value corresponding to the resistance value generated by the thermistor.
WZPK2-475 Armored ThermistorMain technical indicators:
The ratio of the resistance value (R100) of a thermistor temperature sensing element at 100 ℃ to its resistance R0 at 0 ℃: (R100/R0)
Division number Pt100: * R0=100 ± 0.06 Ω
B-class R0=100 ± 0.12 Ω
R0/R100=1.3850
