Armored thermocouple
Product Brief
Armored thermocouple has the advantages of bending, high pressure resistance, fast thermal response time and durability. As a sensor for measuring temperature, armored thermocouple is usually used together with display instrument, recorder and electronic regulator, as well as the temperature sensing element of assembly thermocouple. Armored thermocouple can directly measure the temperature of liquid, steam, gas medium and solid surface in the range of 0 ℃ ~ 1100 ℃ in various production processes.

Note: "t" is the absolute value of the measured temperature.
T-type graduation products need to be ordered through negotiation with our factory.
● Thermal response time of armored thermocouple In case of step change of temperature, the time required for thermocouple output to change to 50% of the step change is called thermal response time, which is expressed by τ 0.5.
The thermal response time of armored thermocouple shall not be greater than that specified in the following table:
