Thermocouple Assembly
Thermocouple Assembly assembles with aluminum protection head, stainless steel thermowell, flange /thread/clamp process connecting , with high pressure resistant, fast thermal response time, high vibration resistance , and long operating life.
Thermocouple Assembly assembles with aluminum protection head, stainless steel thermowell, flange /thread/clamp process connecting , with high pressure resistant, fast thermal response time, high vibration resistance , and long operating life. Its thermo wire diameter is Ф2.5mm. Assembly thermocouple sensor can directly measure the temperature of liquid, vapor, gas medium and solid surface in the range of 0~1000 ℃ in various production processes. Thermocouple sensor is usually used with display instruments, recording instruments and signal conditioners.
