Mini-Hermet Pressure Switch
Brand: CameronMini-Hermet Pressure Switch are robust field-mounted instruments.
The pressure sensing assembly is similar to a conventional type. The main difference is that the switching element assembly is hermetically sealed in an explosion proof steel capsule.
Switching elements are SPDT or DPDT.
