Diaphragm Type


Diaphragm-type Differential Pressure Gauges are available with one or two hermetically sealed reed switches. The switches are adjustable within a defined percentage of the full scale range of the gauge and are available in SPDT and SPST, normally open configurations for various load/power ratings. The switches can be set to activate or deactivate on rising or falling pressure. Switches are “CE” marked per the EU low voltage directive.

Standard configuration can be customized and modified to suit a customer’s need for easy installation or retrofit. Differential Pressure is sensed by the movement of an elastomer diaphragm against a precision calibrated range spring. The change in position of the diaphragm in response to the change in Differential Pressure moves an internal magnet. This magnet, in turn, causes a rotary magnet external to the gauge body to rotate. This rotary magnet has a pointer attached which indicates the differential pressure on the dial.

All Mid-West Diaphragm-type Differential Pressure Gauges can be configured for use in hazardous locations.
