Differential Pressure Gauges from Mid-West Instruments represented by Tech-Quip in Houston, TX. We offer Diaphram and Piston style Differential Pressure Gauges. High accuracy and filter minders low accuracy DP Gagues. Switches can also be added to most every model as well.

What is a Differential Pressure Gauge? A differential pressure gauge is a visual indicator of the net difference in pressure between to points. Each gauge will have both a high and low side to be connected to process taps typically using tubing. The differential pressure gauge will feel the force of the high pressure on one side of the piston or diaphragm and the low pressure on the opposite side, and indicate the net differnce on the face of the gauge.

Piston Type Differential Pressure Gauges & Switches Differential Pressure is sensed by the movement of a precisely ground floating piston/magnet in a precision bore against a calibrated spring. Any variation in pressure on either side of the piston/magnet will cause the magnet to move proportionally to the change in differential pressure. A rotary pointer magnet located close to the internal magnet, but outside the pressure housing, follows the movement of the piston magnet and indicates differential pressure on the dial.
Diaphragm Differential Pressure Gauges & Switches 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.
