102/103 High Static Operation – Explosion Proof Differential Pressure Switch
Brand: SOR Inc
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.
