Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

Remotely monitor the difference in air pressure between two inputs with these transmitters.

View readings at the source with the dial indicator or remotely using a receiver—these transmitters measure the difference in pressure between two inputs in liquid applications.

Check the difference in air pressure between two inputs at the source using the dial indicator or remotely using a receiver.

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications.
