WRGK Sheathed thermоcоuplе

Sheathed thermocouples аre сharacterized у their Slender Shape. fast thermal response, Vibration resistance, ong service life. and еаsе Of bending. These features make them widely used across Various industrial and technological sectors. Such аs aviation. atomic energy, petrochemical, metallurgy, machinery, and power,. etc. They аre particularly suitable fог temperature measurement in environments Where install ation in narrow, Curved pipelines is required. Or where rapid esponse аnd miniaturization are crucial.

WRGK series Sheathed thermocouples аre оцг products made with the ullу imported еqиipment and technology. Which feature the иniqие Structure in а fuli-range of specification. This is the first such product introduced domestically. The product consists Of sheathed thermocouple elements. mounting and fixing devices. Wiring components. and other key parts.

Working Principle

The homogeneous conductor electrode A and BI forms a closed circuit. It is possible to See the current flow in the сircuit When the two Contacts аre at different temperatures. thus сontributing to the thermoelectric EMF - Seebeck potential between the two Contacts. As Illustrated In the working рrinсiplе Schematio. the electromotive fоrce ЕMf has Connection to the materia Of homogeneous сonductor аs Well аs the temрerаtиre difference at both ends. The thermocouple uses this working principle to саrry оut temperature measurement.
