Can a double-wire surface platinum resistance thermometer (turbine type) with low inter-group insulation resistance be used?

Thread Content

I would like to ask the experts: for the two surface platinum resistance elements of the turbine type, WZPM2-001, the insulation resistance between the Pt100 elements is supposed to be 6 MΩ, but the actual insulation resistance of these elements is above 200 MΩ. Can such resistance elements be used?

It should be possible; the higher the insulation resistance between the two resistors, the better

It should be that the greater the inter-group insulation, the better, and this claim is supported.

There should be no problem; check whether the \"SJ 20722-1998 General Specifications for Thermal Resistance Temperature Sensors\" and the \"JB/T 8622-1997 Technical Requirements and Calibration Tables for Industrial Platinum Thermal Resistors\" contain any relevant provisions.
