Insulation resistance thermocouple temperature insulation resistance test voltage is: DC 500 ± 50V. Measuring temperature insulation resistance of atmospheric conditions: temperature 15 ~ 35 ℃ Assembly thermal resistance selection, 45% relative humidity, atmospheric pressure 86 ~ 106kPa. For length> 1 m thermocouple assembly thermal resistance price, temperature insulation resistance value and its length should not be less than 100 MΩ.M product namely: Rr · L> 100 MΩ · m L> 1m formula: Rr- thermocouples temperature insulation resistance value, MΩ; length L- thermocouple assembly thermal resistance, m length ≤1 meter for thermocouple temperature insulation resistance value should not be less than 100 MΩ Model No. indexing structure of temperature range ℃ Protection tube material thermal response time specifications Nominal external antenna lead length L (mm) diameter d (mm) M (mm) WZCM-201Cu50 Cu100 embedded in or fixed screwing -50 to 100 copper T2-Y <15Φ 6M8x0 .75 atmospheric 5001000150020002500WZPM- 201Pt100-150-200 <15Φ 8.7M10x1WZPM-201B Note: WZPM-201B with the introduction of elements WZPM-018, accuracy class A level.
