Temperature is the physical quantity of the body's hot and cold degree. It can indirect measurement through some characteristics (such as resistance, voltage changes and other characteristics) by changing the temperature by objects. The temperature changes and changes, and it has a good reproducibility and stability. The sensor made by using the physical characteristics of this platinum is called a platinum resistor temperature sensor. The zero resistance value of the platinum resistor temperature sensor is 100Q, and the resistance changes are changed. The rate is 0.3851Q/℃. The platinum resistance temperature sensor is high, good, and widely used. It is the most commonly used temperature detector in low temperature zone (-200 ~ 650 ° C). It is not only widely used in industrial temperature measurement And it is made into various standard thermometers (covering the national and world -reference temperature) supply and calculation and calibration.

temperature coefficient

According to IEC 751 international standards, the temperature coefficient TCR = 0.003851, PT 100 (RO = 100Q), PT1000 (R0 = 100Q) are unified design -oriented bureau clearing watermark temperature/medium resistance.
