1Armored thermocoupleOverview
Armored thermocouple is a solid combination of thermocouple wire, insulation material, and metal protective tube assembled and stretched. It has advantages such as bending ability, high pressure resistance, fast thermal response time, and durability.
Armored thermocouples are usually used in conjunction with display instruments, recording instruments, electronic computers, and other devices. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of 0 ℃ -1300 ℃ in various production processes.

4、 Working principle of armored thermocouple
Armored thermocouples are composed of two conductors with different compositions (called thermocouple wires or thermoelectric electrodes) connected at both ends to form a circuit. When the temperature of the junction is different, an electromotive force is generated in the circuit, which is called thermoelectric effect, and this electromotive force is called thermoelectric potential. Thermocouples use this principle for temperature measurement, where the end directly used to measure the temperature of the medium is called the working end (also known as the measuring end), and the other end is called the cold end (also known as the compensating end); Connect the cold end to the display instrument or matching instrument, and the display instrument will indicate the thermal potential generated by the thermocouple.
Thermocouples are actually energy converters that convert thermal energy into electrical energy and measure temperature using the generated thermoelectric potential.
