The working temperature of the pt100 resistance and measurement range

Although the pt100 resistance is also widely applied in industry, but because of his temperature range makes his application by certain restrictions, pt100 temperature measuring principle of thermal resistor is based on the conductor or semiconductor resistance changes with the change in temperature. Its many advantages, can also remote transmission signal, high sensitivity, strong stability, compatibility and accuracy are better, but you need to power, can't instantaneous measured the change in temperature. Industrial heat resistance generally adopts Pt100, Pt10 Cu50, Cu100, platinum thermal resistance temperature measurement range is generally 200 - below zero 800 ℃, the thermal resistance of copper of 40 to 140 ℃ below zero. Thermal resistance and thermocouple as the distinction between the type, but he does not need compensation conductor, and is much cheaper than explosion-proof thermocouple.

the main performance of the pt100 resistance

1, pt100 thermal resistance temperature measurement principle is based on a conductor ( Or a semiconductor) To measure the properties of resistance varies with temperature changes, explosion-proof thermal resistance measurement range is negative 00 ~ 500 degrees, commonly used have the platinum resistance ( 装Pt100 Pt10) Cu50, copper resistance ( Negative 50 - 150 degrees) 。

2, pt100 thermal resistance signal, the properties of heat resistance itself is resistance, the change of the temperature, the resistance produce positive or negative resistance changes; And thermal coupling, it is the change of the induced voltage, he along with the change of temperature change.

3, two kinds of sensors to detect temperature range, thermal resistance 0 - general detection The temperature range of 150 degrees, the highest measurement range can be up to 600 degrees ( Of course can detect negative temperature) 。
