1) The insulating layer of the armored thermocouple has limited conductivity, and the insulation resistance value decreases with the increase of the length of the armored thermocouple, so the electrical conductivity of the armored thermocouple is represented by Sm-1 (equal to Ω -1 m - 1 ), so the minimum insulation resistance of armored thermocouples with a length greater than 1m is represented by Ωm or MΩm, and those less than 1m are represented by MΩ;
