Detailed Product Description

The Features of Thermal Resistance

1.Simple structure and good stability performance.

2.High measuring accuracy.

3.High mechanical strength, good pressure-resisting performance.

The Application

It is usually connected with display meter, recording meter and computer ect. to directly measure the temperature of liquid, vapor, gas and solid surface ranging from -200^oC to 450^oC during various production processes.

The Main Technical Parameters

1.Standard: IEC 751, JB/T 8622-1997, JB/T 8623-1997.

2.Insulation Resistance at Normal Temperature: The insulation resistance of  Pt thermal resistance shall be no less than 100MΩ, and the insulation resistance of Cu thermal resistance should be no less that 50MΩ under condition that environment temperature is 15~35^oC, relative humanity is no more than 80%, testing voltage is 10~100v(D.C).

3.Thermal Response Time: When the temperature has step-jumping change, the needed time for output of thermocouple changes to 50% of the step-jumping change, this time is called thermal response time, indicating with t 0.5.
