Refill U-tube gauges.

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity changes in air applications. They are also known as manometers.

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Use in medium-pressure applications up to 1,500 psi.

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

Also known as pitot tubes, these can be used with manometers to measure air flow rate.

With a digital display and selectable differential pressure ranges, these transmitters are a versatile alternative to transmitters with dial indicators.

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.

Measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. These transmitters automatically compensate for errors caused by vibration and temperature changes.
