About Pressure Gauges

Pressure Gauges

These are the most commonly used pressure gauges. Use them with pumps, filters, regulators, and in process lines to measure and display pressure.

Miniature Pressure Gauges

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

Digital High-Accuracy Pressure Gauges

A digital display allows for easy reading of measurements.

High-Accuracy Low-Pressure Gauges

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

Low-Pressure Differential Gauges with Color Indicator

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

Gauge Guards

Also known as isolators or diaphragm seals, these protect gauges from corrosive process media.

Pressure Transmitters

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

Pressure Transmitters with Digital Display

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

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.

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.

Sanitary Pressure Transmitters

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

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.

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.

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.

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.

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.

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.

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.

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.

Differential Pressure Transmitters

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

Low-Pressure Differential Pressure Transmitters

Often used in HVAC systems and clean room airflow monitoring applications, these transmitters measure the difference in pressure between two low-pressure process lines.

Easy-Setup Differential Pressure Transmitters

Measure the difference in pressure between two process lines in flow applications such as heat exchangers, chillers, and pumps. 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.

Convert 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 vacuum or control equipment.

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.

High-Accuracy Test Gauges for Pressure

With an accuracy of ±0.25%, these gauges are designed for critical processes that require precision.

Pressure-Regulating Valves

Tank-Mount Pressure-Regulating
Valves for Air and Inert Gas

These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure.

High-Purity Tank-Mount
Pressure-Regulating Valves for Inert Gas

Reduce contaminants in gases used in research sample systems, emission monitoring systems, chromatography, and other high-purity applications. These valves have a 316 stainless steel and brass body with a smooth finish to reduce dust collection and internal components designed to protect the seal and diaphragm from contamination.

Easy-Read Tank-Mount Pressure-Regulating
Valves with Flowmeter for Inert Gas

Flowmeters let you see the gas flow rate from a distance.

Tank-Mount High-Pressure-Regulating
Valves for Air and Inert Gas

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves.

Tank-Mount Pressure-Regulating
Valves for Moisture Removal

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems.

Tank-Mount Pressure-Regulating
Valves for Cryogenic Cylinders

Choose from valves for liquid argon, liquid nitrogen, liquid carbon dioxide, or liquid oxygen tanks.

Charging and Gauging Kits for Hydraulic Accumulators

These kits include the hose, gauge, and fittings needed to charge an accumulator.
