Differential Pressure Gauges

Product Description:
A low cost differential pressure gauge for use in measuring the pressure drop across filters, strainers, separators, valves, pumps, chillers, etc. and for local flow indication and control.

Differential pressure is sensed by the movement of a floating piston magnet against a calibrated spring. The gauge pointer, outside the pressure housing, follows the movement of the piston magnet and indicates differential pressure. Available with magnetically actuated hermetically sealed CSA listed reed switches to provide high and low limit alarm or control.

An optional maximum indication follower pointer provides automatic indication of maximum differential occurring during a time period or system cycle. Reversed pressure ports are available as an option when installing for readability depending on which side of a filter, etc.,
