Armored thermocouple of waterproof
Overview of Armored thermocouple of waterproof
Waterproof Armored thermocouple is usually used together with display instrument, recording instrument, electronic computer, etc. Directly measure the surface temperature of liquid, steam, gas medium and solid in various production processes.
1. Application of waterproof armored thermocouple
It is usually used together with display instrument, recording instrument, electronic computer, etc. Directly measure the surface temperature of liquid, steam, gas medium and solid in the range of 0 ° c~1300 ° C in various production processes.
2. Features of armored thermocouple of waterproof
The thermal response time is less, and the dynamic error is reduced;
Flexible installation and use;
Large measuring range;
High mechanical strength and good pressure resistance;
3. Operating principle of armored thermocouple of waterproof
The electrode of armored thermocouple is composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, the thermal potential will be generated, and the working instrument will display the temperature value corresponding to the thermal potential.

6. Insulation resistance at normal temperature
The insulation resistance between the armored couple and the outer sleeve is more than 1000m Ω when the ambient temperature is 20 ± 15 ° C and the relative humidity is not more than 80% and the test voltage is 500 ± 50V (DC). That is, the insulation resistance of 1m long sample is 1000m Ω; The insulation resistance of 10m long sample is 100m Ω;
