About Pressure Gauges

Low-Pressure Differential
Gauges with Color Indicator

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

Low-Pressure Differential Gauges with Dial Indicator

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

Low-Pressure Differential Gauges with U-Tube

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.

Low-Pressure Differential Gauges with Inclined Scale

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.

Low-Pressure Differential
Gauges with Digital Display

Gauges have a digital display for easy reading of measurements.

High-Pressure Differential Gauges

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

Medium-Pressure Differential Gauges

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

Differential Pressure and Vacuum Gauges

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

Differential Pressure and Vacuum
Gauges with Digital Display

Gauges have a digital display for easy reading of measurements.

Differential Pressure Transmitters

Differential Pressure Transmitters
with Dial Indicator for Liquids

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.

Differential Pressure Transmitters
with Digital Display for Air

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

Differential Pressure Transmitters for Liquids

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

Differential Pressure Transmitters
with Dial Indicator for Air

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

Differential Pressure Transmitters
with Electronic Switch Outputs

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.

High-Accuracy Differential Pressure Transmitters

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

Differential Pressure Transmitters for Air

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

Easy-Setup Differential Pressure Transmitters

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.

Hazardous Location Easy-Setup
Differential Pressure Transmitters

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.
