About Pressure Gauges

High-Accuracy Low-Pressure Gauges

Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes.

Digital High-Accuracy Pressure Gauges

A digital display allows for easy reading of measurements.

Colored-Case High-Accuracy Pressure Gauges

Gauges come in a variety of colors so you can identify an important spot in your process line.

Miniature Pressure Gauges

The small dial on these gauges allows for installation in tight spaces.

Square Panel-Mount Pressure Gauges

These gauges fit into square cutouts in your instrument panel.

Corrosion-Resistant Pressure Gauges

Gauges have an accuracy of ± 2%.

High-Accuracy Corrosion-Resistant Pressure Gauges

Gauges have an accuracy of ± 1% to ± 1.5%. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

Vibration-Resistant Pressure Gauges

A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications.

Extreme Vibration-Resistant Pressure Gauges

Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer.

Maximum-Indicating
Vibration-Resistant Pressure Gauges

These gauges have a red needle that indicates the highest pressure reached since the last setting. They have a liquid-filled dial that reduces needle flutter for precise readings in high-vibration applications.

Vibration- and Corrosion-Resistant Pressure Gauges

The case material and connection threads are stainless steel for protection in corrosive environments, plus the dial is glycerin-filled to reduce needle flutter in high-vibration applications.

High-Clarity Vibration- and
Corrosion-Resistant Pressure Gauges

These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings.

Extreme-Temperature Pressure Gauges

These gauges can withstand both extremely cold and extremely hot temperatures.

Gas Pressure Gauges

Use these gauges to monitor the pressure of compressed gas.

Vibration-Resistant Pressure Gauges for Chemicals

These gauges have a liquid-filled dial that reduces needle flutter in high-vibration applications reaching 2,000 psi.

Low-Pressure Gauges for Chemicals

Use in low-pressure applications up to 160 psi.

High-Pressure Gauges for Chemicals

Use in high-pressure applications up to 2,000 psi.

Pressure Transmitters

Pressure Transmitters with Digital Display

Read pressure directly at the source and send data remotely with one device.

Pressure Transmitters

Remotely monitor pressure in general purpose applications such as pumping and compressing systems.

Washdown Pressure Transmitters

For use in wet environments, these transmitters are rated NEMA 4X for protection from washdowns and corrosion.

Sanitary Pressure Transmitters

For use in sanitary applications such as food processing, these transmitters are 3-A certified.

Absolute Pressure Transmitters
for Development Boards

Measure your equipment’s pressure and send the data directly to a development board or single-board computer. Also known as transducers, these transmitters convert pressure into an electrical I²C signal and transmit it to your board.

Absolute Pressure Transmitters

Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature.

Wireless Pressure Transmitters

Remotely track your system's pressure readings from the convenience of a smartphone or tablet. Good for preventative maintenance and route-based monitoring, these battery-powered transmitters use Bluetooth to alert you when equipment requires your attention.

High-Accuracy Pressure Transmitters

At least five times as accurate as standard pressure transmitters, these transmitters sense pressure at an accuracy of ±0.1%, making them ideal for use in laboratories and in analytical testing applications.

Easy-Setup Pressure Transmitters

These transmitters automatically compensate for error introduced by vibration as well as temperature fluctuations, so you do not need to program your receiving device to correct for these factors. They convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment.

Sanitary Easy-Setup Pressure Transmitters

Used in food-processing and pharmaceutical plants to automatically compensate for temperature changes and errors caused by vibration, these transmitters have a sanitary design certified by 3-A.

Hazardous Location Easy-Setup Pressure Transmitters

Safely monitor liquid, gas, and steam pressure in hazardous locations with these transmitters. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

Differential Pressure Transmitters

Measure the difference in pressure between two points in flow applications, such as heating, cooling, and pumping systems.

Vacuum Transmitters

Washdown Vacuum Transmitters

These transmitters are rated NEMA 4X for protection from washdowns and corrosion.

Sanitary Easy-Setup Vacuum Transmitters

Monitor and control equipment in food-processing and pharmaceutical plants—these transmitters convert vacuum into electrical signals for receiving devices and have a 3-A certified sanitary design. They automatically compensate for vibration and temperature changes, saving you the effort of programming manual corrections.

Pressure and Vacuum Transmitters

Convert both pressure and vacuum into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment.

Hazardous Location Easy-Setup
Pressure and Vacuum Transmitters

Used in hazardous locations, these transmitters safely convert pressure and vacuum into an electrical signal to measure liquids, gases, and steam. NEC rated for safety, these transmitters are explosion proof, so they can be used in environments containing flammable gases and vapors.

Sanitary Easy-Setup Pressure
and Vacuum Transmitters

Designed for sanitary environments, these transmitters automatically compensate for error in vacuum and pressure measurements caused by vibration and temperature fluctuations, so you don’t need to program corrections into your receiving device.

High-Accuracy Pressure and Vacuum Transmitters

With an accuracy of ±0.25%, use these transmitters in applications that require highly accurate measurement of both pressure and vacuum, such as activating vacuum pumps.

Easy-Setup Pressure and Vacuum Transmitters

These transmitters automatically compensate for error introduced into both pressure and vacuum measurements by vibrations as well as temperature fluctuations, so you do not need to program corrections for these factors into your receiving device. They convert pressure and vacuum to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment.

Pressure and Vacuum Transmitters with Digital Display

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on a display. With two outputs, these transmitters—also known as transducers—can be used as a transmitter, a switch, or both.
