1、Application
Specialized for the petrochemical sector design, can directly measure -200 ℃ -1600 ℃ range of liquid, steam and gas media and solid surface temperature measurement.
2、Working Principle
The electrode of thermocouple consists of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermal potential will be generated, and the working instrument will display the temperature value corresponding to the thermal potential.
RTD is the use of resistance and temperature as a function of the relationship between the principle. When the measured medium has a temperature change, its resistance value also changes, the working instrument will display the temperature value corresponding to the resistance value.
3、Main Technical Parameters
Product Implementation Standard: IEC1515
IEC1515
IEC584
IEC751
JB/T5518-91
JB/T5582-91
4、Nominal pressure
Generally refers to at room temperature, the protection of the tube can withstand the static external pressure without rupture. Allowable working pressure is not only related to the protective tube material, diameter, wall thickness, and its structure, installation methods and the measured medium flow rate, type of related.
