Application

It is usually connected with displaymeter, recording meter and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from -200 C to 500C during various production process.

Operation Theory

It is based on that temperature change of material results in change of its resistance. When resistance ＆#118alue changes, the working instrument will display relevant temperature.

Main Technical Parameters

Ratio of resistance ＆#118alue at 100C （R100）and resistance ＆#118alue at 0C （R0）,
R100/ R0

Graduation : Pt100： class A R0＝100±0.06Ω
class B R0＝100±0.12Ω
W100＝R100/ R0＝1.3850
