Medium and low temperature resistance temperature sensor temperature measuring element

Medium and low temperature resistance temperature sensor temperature measuring elementwzpk-131It is a temperature sensor with a smaller diameter than prefabricated platinum resistors, easy to bend, and good seismic resistance. It is suitable for installation in situations where prefabricated platinum resistors cannot be installed. The armored thermistor adopts imported platinum resistance temperature measuring elements, which have the advantages of precision, sensitivity, fast thermal response time, stable quality, and long service life.

Medium and low temperature resistance temperature sensor temperature measuring elementwzpk-131The outer protective sleeve is made of stainless steel and filled with high-density oxide material insulation. Therefore, it has strong anti pollution performance and excellent mechanical strength, making it suitable for installation in harsh environments.

It can be directly connected to secondary instruments using copper wires. Due to its excellent electrical output characteristics, it can provide accurate temperature change input signals for displays, recorders, regulators, scanners, data loggers, and computers.

working principle

Working principle of armored thermistor: The resistance of platinum resistance wire changes with temperature. The display instrument will indicate the temperature value corresponding to the resistance value generated by the platinum resistor.

1． Nominal Pressure

Generally refers to being at room temperature,The protective tube can withstand static external pressure without breaking,The test pressure generally adopts the nominal pressure1.5Twice. In fact, the allowable nominal pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to its structural form, installation method, insertion depth, as well as the flow rate and type of the measured medium.

2． Thermal response time

When there is a step change in temperature, the output of the thermal resistor changes to a level equivalent to the step change50%The required time, called thermal response time, is usedT0.5express.

3． Thermal resistance insulation resistance

The test voltage for insulation resistance at room temperature can be taken as DC10~100VAny value, the ambient temperature should be within15~350CWithin the range, the relative humidity should not exceed80%The insulation value at room temperature should not be less than100MΩ.
