SOR Differential Pressure Switch, 102/103
102/103 differential pressure switches are robust field-mounted instruments. 

The 102 pressure sensing assembly is a piston; the 103 pressure sensing assembly is a diaphragm-piston combination. 

The 102/103 can be configured for service in non-hazardous and hazardous locations. Switching elements are SPDT or DPDT.
