Thermal Resistance Insulation Resistance Data

---- In the room temperature 15 to 35, relative humidity ≤ 80%, the experimental voltage 100V.DC insulation resistance should not be less than 100 (MΩ)

Thermocouple high temperature insulation resistance

Insulation resistance (MΩ) K, N, B, J 500 ± 15 ≥5 T 300 ± 10 ≥500 Note: When the temperature is higher than 300 ℃, the insulation resistance decreases rapidly, and the value is Small, easy to introduce the interference caused by leakage, receiving thermocouple signal speed, display instrumentation should generally be input / output isolation measures.

High - temperature insulation resistance

Operating temperature tm (℃) Test temperature t (℃) Insulation resistance (MΩ)

100 ≤ t ≤ 300 t = tm ≥ 10 300 ≤ t ≤ 500 ≥ 2 500 ≤ t ≤ 850 ≥ 0.5
