Overview
WRPK-171, WRMK-471 series flat plug-in thermocouple
Product Details
Flat plug-in armored thermocouple
1. Application of Flat Plug Armored Thermocouples
Usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the surface temperature of liquids, vapors, gases, and solids within the range of 0 ° C to 1300 ° C in various production processes.
2. Characteristics of Flat Plug Armored Thermocouples
Less thermal response time, reducing dynamic errors;
Flexible installation and use;
Large measurement range;
High mechanical strength and good pressure resistance;
3. Working principle of flat plug-in armored thermocouple
The electrodes of armored thermocouples are composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
4. Main technical parameters of flat plug-in armored thermocouple
Product execution standards
IEC584
IEC1515
GB/T18404-2001

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