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.

Our 1516 Series models are our most popular diaphragm sensor design. They combine a highly sensitive sensor with high line pressure capabilities.

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.

Our 1800 Series models are our most sensitive sensor designs. While being sensitive they also handle high line pressures up to 150 psi!

Note: Select these diaphragm models for air or gas applications or where fluid migration from the high to low pressure ports cannot be tolerated.

Switches, Relays, Transmitters

A variety of reed switches and relays 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 a voltage output.

Features

• Low DP ranges at high line pressures
• Rugged, weatherproof design
• Gauge, switch and transmitter versions
• Popular in filtration, flow and level measurements

Our new two-wire, loop-powered transmitter offers users more flexibility. Because there is no need to bring external power to the unit, installation time and cost are reduced.

Offered on:

>> Differential pressure (with indicator option)

>> Flow (with indicator option)

A 4-20 mA (two wire) output is available for loop-powered installations, which offers the user the most savings in installation. A 0-5 VDC (three or four wire) output also is available as standard. The input voltage is 9-35 VDC.

The transmitters are built on the same pressure body as our high line pressure (to 5,000 psi) gauges and switches. Select from many different pressure ranges (0-5" H2O to 0-1000 psid) and flow ranges (0-1 GPM to 0-10 GPM).

Built for difficult industrial applications, a weatherproof enclosure protects the electronics with Class 1, Div. 1&2, Nema 4X and IP65 ratings. A 7/8" (22 mm) knockout is standard for 1/2" conduit connections.
