A grade

B grade

Description: tis temperature absolute value measured by temperature-sensing element

Thermal Response Time

Normal Temperature Insulation Resistance

    Note: the test condition is: ambient temperature 15-30C, environmental humidity is not more than 80%, the experimental voltage is any value between DC 10-100V, measuring insulation resistance between the electrode and the outer jacked.

Upper Temperature Insulation Resistance

Temperature Value

Minimum Allowable Values

The upper limit temperature insulation resistance of Cu resistance shall be not less than 10M.

Minimum Insertion Depth

   The depth of the heat resistance protection tube insertion media is generally not less than the sum of resistive element length (about 50mm) and the outer diameter size of 8 to 10 times (except for the special products)
