Differential Pressure Gauges

Differential pressure gauges are visual indicators designed for measuring and illustrating the difference between two pressure points. Raptor Supplies offers an array of differential pressure gauges from brands like Ashcroft, Dwyer Instruments, Midwest Instrument, Plast-O-Matic, UEI Test Instruments. These gauges have two inlet ports each connected to the pressure points being monitored. Dwyer Instruments differential pressure gauges combine different control functions into a single, easy-to-install package and are capable of measuring positive, negative and differential pressures within +/-2% of full-scale accuracy and provides a highly dependable analogue indication of air or gas pressure on a 4-inch, 80-degree scale. Plast-O-Matic differential pressure gauges are engineered for measuring the difference in pressure between two points in a system and then present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressure points, while completely isolating the gauge function from the pressure chamber. Choose from a wide range of these pressure gauges available in 1/4 inch FNPT, 1/4 inch NPT and 1/8 inch NPT connection sizes on Raptor Supplies.
