Professional design for the petrochemical sector, can be directly measured in the range of -200 ℃ -1600 ℃ liquid, vapor and gases and solid surface temperature.

working principle

Thermocouple electrode composed of two different conductor materials. When measuring side and reference junction temperature difference, it will generate thermoelectric power, work thermoelectric power meter will show the corresponding temperature value.

Thermal resistance is the use of resistance and temperature relationship principle was a certain function. When the measured medium temperature change, its resistance value also changes, the working instrument will show the resistance values ​​of the corresponding temperature value.
