              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.

              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:

              Thermal response time τ 0.5s
