product details

Product Name.

Petrochemical thermocouple / RTD

Product Description.

appliance

Specialized for the petrochemical sector design, can be directly measured within the range of -200 ° C to 1600 ° C liquid, steam and gas media, as well as solid surface temperature measurement.。

Working Principle

The electrodes of a thermocouple consist of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential is generated and the working instrument displays the temperature value corresponding to the thermoelectric potential.

RTDs utilize the principle that resistance is a function of temperature. When the measured medium has a temperature change, its resistance value also changes, and the working instrument shows the temperature value corresponding to the resistance value.

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 structural form, installation methods and the measured medium flow rate, type.
