The wire connected with Platinum Resistor Temperature Sensor WZPM-201 is sleeved with a stainless steel sheath. The wire and sheath are insulated and armored. The resistance value of the platinum resistance changes with temperature in a linear relationship. The deviation is extremely small, and the electrical performance is stable. It is resistant to vibration, high in reliability, and has the advantages of precise sensitivity, stable performance, long product life, easy installation and no leakage of oil.
Working principle
The Resistor Temperature Sensor WZPM-201 measures the temperature by using the characteristic that the resistance of the material changes with the temperature. The heated part of the thermal resistor (temperature sensing element) is evenly wrapped on the skeleton made of insulating material with thin metal wires. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium layer within the range of the temperature sensing element.

Heat response time: When the temperature changes in a step, the time required for the output of the thermal resistor to change to 50% of the step change is called the thermal response time, which is expressed in T0.5.
