Overview
Armored thermocouples are usually used in conjunction with display instruments, recording instruments, electronic computers, and other devices. Armored thermocouples directly measure the surface temperature of liquids, vapors, gases, and solids within the range of 0 ° C to 1300 ° C in various production processes.

Product Introduction
sheath thermocoupleUsually used in conjunction with display instruments, recording instruments, electronic computers, etc.sheath thermocoupleDirectly measure the surface temperature of liquids, vapors, gases, and solids within the range of 0 ° C to 1300 ° C in various production processes.
sheath thermocouplefeature
Less thermal response time, reducing dynamic errors;
Flexible installation and use;
Large measurement range;
High mechanical strength and good pressure resistance;
sheath thermocoupleworking principle
The electrode is 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.

Room temperature insulation resistance
sheath thermocoupleAt an ambient temperature of 20 ± 15 ° C and a relative humidity of no more than 80%, the test voltage is 500 ± 50V (DC), and the insulation resistance between the electrode and the outer sleeve is greater than 1000M Ω. That is, the insulation resistance of a 1m long sample is 1000M Ω; the insulation resistance of a 10m long sample is 100M Ω;
