Thermocouple temperature insulation resistance details

Thermocouple temperature insulation resistance - - - - Insulation type sheathed thermocouples in the environmental temperature is 20 + 15 ℃, relative humidity is not more than 80%, the thermal electrode and the insulation resistance between metal coat should conform to the specified value in the table below. The casing diameter ( mm) Test voltage ( V。 DC) Insulation resistance ( MΩ。 m)

0。 5 ~ 1. 5 50±5 ≥1000 ＞1. 5 to 500 + 50 note: M Ω. M units said insulation resistance and armoured accidentally element length value, the product of length L ( m) The insulation resistance of R/L (1000 or more MΩ)

thermal resistance temperature insulation resistance details

- - - - 15 ~ 35 at room temperature, relative humidity of 80% or less, the experiment voltage 100 v. DC insulation resistance shall be not less than 100 ( MΩ)

thermocouple temperature insulation resistance

dividing test temperature ( ℃) Insulation resistance ( MΩ) K, N, B, J 500 + 15 p 5 T 300 + 10 or 500 note: when using the temperature higher than 300 ℃, insulation resistance decrease faster, smaller, and values, to introduce the leakage of interference, receive thermocouple signal transmission, display instrument should be generally by the input/output isolation measures.
