About This Product

Zener barrier for thermocouples with intrinsically safe explosion-proof structure. In combination with this barrier, it can be used as a sensor to measure the temperature of various objects, such as the atmosphere in hazardous areas, the temperature inside piping, and the temperature inside furnaces. Compared to resistance temperature detectors, it can be used for high temperature objects.

■Common precautions regarding Zena Barrier

- Only sensors that have passed the combination test can be used. ・Please store in a non-hazardous location and in a container with IP20 or higher rating.

■Notes

・Wiring/operation/maintenance/inspection work should be carried out by someone with specialized knowledge and skills in the construction of explosion-proof electrical equipment and related laws and regulations. - When installing in a hazardous location, the hazardous area where it can be installed varies depending on the model, so be sure to check the corresponding hazardous area. ・Specifications/design etc. are subject to change without notice.
