Thermometers
Armored thermocouple

具有能弯曲、耐高压、热响应时间快和坚固耐用等优点, 铠装热电偶与装配式热电偶一样,作为测量温度的传感器,通常铠装热电偶和显示仪表、记录仪和电子调节器配套使用,同时,铠装热电偶亦可以作为装配式热电偶的感温元件。 Armored thermocouples have the advantages of bending, high voltage resistance, fast thermal response time, and ruggedness. Like armored thermocouples , armored thermocouples are used as temperature sensors. Electronic regulators are used together. At the same time, armored thermocouples can also be used as temperature sensing elements for assembled thermocouples. Armored thermocouples can directly measure the temperature of liquid, steam and gaseous media and solid surfaces in the range of 0 ℃ ~ 1100 ℃ in various production processes. zzyfwh.com

热响应时间 ● Thermal response time of armored thermocouple
When there is a step change in temperature, the time required for the thermocouple output to change to 50% of the step change is called the thermal response time, which is expressed by τ0.5.
The thermal response time of the armored thermocouple is not greater than the following table:
