High temperature armored thermocouple -2025

1High temperature armored thermocoupleApplication:

Directly measure the surface temperature of liquids, vapors, gases, and solids within the range of 0 ° C to 1300 ° C in various production processes.

2High temperature armored thermocoupleFeatures:

·Less thermal response time, reducing dynamic errors;

·Flexible installation and use;

·Large measurement range;

·High mechanical strength and good pressure resistance;

3. Working 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.

4. Advantages of High Temperature Armored Thermocouples

Armored thermocouples have many advantages such as bending, high voltage resistance, fast thermal response time, and durability. Like industrial assembled thermocouples, they are commonly used as temperature sensors in conjunction with display instruments, recording instruments, and electronic regulators. At the same time, they can also be used as temperature sensing elements for assembled thermocouples. It can directly measure the temperature of liquids, vapors, gas media, and solid surfaces in the range of 0 ℃~800 ℃ during various production processes. Compared with prefabricated thermocouples, armored thermocouples have advantages such as bendability, high voltage resistance, short thermal response time, and durability.
