Analog Pressure Gauges

Dwyer® Series 2000 Magnehelic® Gage offers analog frictionless movement to indicate positive, negative, or differential pressure in air or noncorrosive gases within 1% accuracy .

Photohelic® Pressure Switch/Gage functions as versatile, highly repeatable pressure switch combined with a precise pressure gage. Applications include air conditioning systems, clean rooms, and fume exhaust systems.

The Series 4000 Capsuhelic® Differential Pressure Gage is designed to give fast, accurate indication of differential pressures. The gage may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure. The pressure being measured is held within a capsule which is an integral part of the gage. This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in w.c.

Photohelic® Switch/Gage combines functions of a precise, highly repeatable differential pressure switch with a large analog pressure gage. Applications include air conditioning systems and pneumatic conveying.

Magnehelic® Differential Pressure Gages has a bright red LED on right of scale that shows when setpoint is reached. Field adjustable from gage face.

Mini-Photohelic® Differential Pressure Switch/Gage combines the differential pressure gage with two SPDT switching set points. Designed to measure and control positive, negative, or differential pressures.
