Miniature Differential Pressure Gauges

These miniature 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. Both piston and diaphragm sensor models are available as in our standard size instruments. Their small size and low cost make them ideal for OEM use.

We offer them with bodies (and wetted parts) of aluminum. The indicator models come standard with a 1" molded plastic lens while a 2" dial is available as an option. A variety of porting options allow for any mounting configuration.

A red/green dial with a breakpoint located at 70% of full scale alerts the user of the condition of the process. This matches the setpoint of the reed switch if ordered together.

Note: Our piston sensor models are best for liquid applications as they have a slight amount of fluid migration from the high to low pressure ports. Select our diaphragm models for air or gas applications or where fluid migration cannot be tolerated.
