Detail:
Product Name: Petroleum Chemical thermocouple / thermal resistance
Product features:
1, application
Professional for the petroleum chemical industry design, direct measurement of 200million DEG C 1600 temperature range of liquid, steam and gas medium and solid surface temperature measurement.
2, working principle
The electrodes of the thermocouple are made of two different materials. When there is temperature difference between the measuring end and the reference end, it will generate the thermal potential, and the working meter will show the corresponding temperature value of the thermal potential.
The thermal resistance is the relationship between the resistance and temperature. When the temperature changes in the medium, the resistance value is changed with the change of the working meter will show the corresponding temperature value of the resistance value.
3, the main technical parameters
Product implementation standard:
IEC1515
IEC584
IEC751
JB/T551891
JB/T558291
4, nominal pressure
Generally refers to the temperature, the protection of the tube can withstand the static external pressure without rupture. Allowable working pressure is not only related to the protection of pipe material, diameter, wall thickness, but also its structure, installation method and the flow rate and type of the measured medium.
5, temperature range and tolerance
