Assembly Thermocouple directly measures the temperature of liquid, steam and gas medium and solid surface in the range of 0°C-1800°C in various production processes. It is easy to assemble and replace, and the pressure spring type temperature sensing element has good anti-vibration performance and temperature measurement. Large range, high mechanical strength, good pressure resistance, widely used in electric power, thermal power, metallurgy, medicine, chemical, machinery manufacturing and other industries.
