*Fluorosilicone diaphragm is standard for 0-10 psid, Buna diaphragm is standard for above 0-10 psid
**Ranges available by diaphragm material:
-- Fluorosilicone: 0-10 to 0-300 psid
-- Buna: 0-15 to 0-300 psid
-- EPDM: 0-15 to 0-300 psid
-- Viton: 0-25 to 0-300 psid
***NEMA 4X switch models have a 1/2" NPT
conduit port as standard (all other have 1/4" NPT standard).

Gauge (w/switch option): 1533DGS - 1A - 2.5B - A 0-15 psid, 2 switch to close at 10 psid ascending
Switch only (no gauge): 1533DS - 1C - A 0-15 psid switch to close at 10 psid ascending
Diaphragm Sensor Differential Pressure Gauges
These diaphragm sensor 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.
We offer them with bodies (and wetted parts) of aluminum, stainless steel or brass. A variety of dial sizes are also available, from 2.5 inch to 6 inch, with many porting and mounting configurations. Choose from a wide selection of standard options; enough to satisfy any requirement.
Note: Select these diaphragm models for air or gas applications or where fluid migration from the high to low pressure ports cannot be tolerated. Avoid applying reverse pressure when attaching to systems. This can damage the diaphragm sensor.
Switches, Relays, Transmitters
A variety of reed switches, relays and transmitters can accompany the 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.
