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.
