FE Series Temperature Switch

Brand: Orion Instruments

These switches have been designed for use in hazardous area and for severe applications in the oil and gas sectors like oil and gas pipelines, petrochemical plants, refineries and generally in atmospheres which are potentially explosive. 

All switches are designed for gas group IIC, the most severe of the explosive gases, and hence can be used in lower severity atmospheres, typically in IIA and IIB. 

With grey cat iron enclosures, these can also be used in mines. 

SS Enclosures can also be offered for highly corrosive atmospheres. 

Switches can be configured with a lot of options like electrical elements and sensing element configurations to suit the intended working media.
