Armored thermal resistorIt is a temperature sensor that has a smaller diameter, is easy to bend, and has good seismic resistance compared to prefabricated thermal resistors. It is suitable for installation in situations where prefabricated thermal resistors cannot be installed. The WZPK series armored thermal resistors produced by our company use imported thermal resistance temperature measuring elements, which have the advantages of precision, sensitivity, fast thermal response time, stable quality, and long service life.
The outer protective sleeve of the armored thermal resistor is made of stainless steel and filled with high-density oxide material insulation. Therefore, the armored thermal resistor has strong anti pollution performance and mechanical strength, making it suitable for installation in harsh environments.
　　Armored thermal resistorIt can be used to measure temperatures within the range of -200 to 600 ℃, and can be directly connected with copper wires and secondary instruments. Due to the excellent electrical output characteristics of armored thermal resistors, it can provide accurate temperature change signals for display instruments, recorders, regulators, scanners, data recorders, and computers.
● Working 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.
● Main technical indicators
The ratio of the resistance value (R100) of the thermistor temperature sensing element at 100 ℃ to its resistance R0 at 0 ℃: （R100/R0）
Division number Pt100: Class A R0=100 ± 0.06 Ω
B-class R0=100 ± 0.12 Ω
R0/R100=1.3850
