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

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.

Use in high-pressure applications up to 3,000 psi.

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

Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment.

Safe for use in environments where flammable gases and vapors are present, these transmitters measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. They meet NEC safety standards for protection against an explosion.

Used with pumps, cooling systems, and other liquid applications, these transmitters remotely measure the difference in pressure between two inputs.

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.

At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%.
