Hazardous location, high pressure differential pressure gauges measure the pressure difference between two points. Acting in the place of two pressure gauges, these units allow for one simple reading on an easy-to-read scale. Popular in filtration, flow and level applications, they are a low cost alternative to bourdon tube and bellows designs.
These hazardous location differential pressure instruments are used in environments containing hazardous vapors, gases or particulates. The switches and electrical connections are housed in special UL, CSA, FM and ATEX approved enclosures. The cast aluminum housings have two mounting lugs, a 3/4" NPT electrical conduit port, and meet the following specifications: Class 1, Gr. B, C, & D; Class II, Gr., E, F, & G; and Class III. They also meet NEMA 3, 4X, 7, 9, & 12 specifications.
We offer our explosion proof, high pressure gauges with bodies (and wetted parts) of aluminum and stainless steel. A variety of dial sizes are also available, from 3.5 inch to 6 inch, with many porting and mounting configurations. Choose from a wide selection of standard options; enough to satisfy any requirement.
A variety of reed switches, relays and transmitters can accompany the differential pressure gauges or be supplied on their own, without a dial. SPST switches are offered normally open (N.O.) or normally closed (N.C.). SPDT reed switches also are available. DPDT relays are offered for high inductance applications, such as those incorporating motors or solenoids. Transmitters offer a current or voltage output. Contact us for more information on switches, relays and transmitters.
