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

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.

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.

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.

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

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

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