Designed for use with boilers, these gauges measure pressure and temperature simultaneously.

Use these gauges to monitor the pressure of compressed gas.

Gauges have a digital display for easy reading of measurements.

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

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.

Gauges have a digital display for easy reading of measurements.

Use these gauges with vacuum pumps, packaging equipment, and in suction lines to measure and display vacuum.

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial to reduce needle flutter.

The case and connection threads are stainless steel for protection in corrosive environments.

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.

A digital display allows for easy reading of measurements.

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. Gauges have a digital display for easy reading of measurements.

Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement.

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial that reduces needle flutter.

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.

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

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

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.

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.

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display.

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.

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.

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

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.

Gauges have an accuracy of ±0.25%.

These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications.

All-stainless steel construction makes these gauges suitable for testing and calibrating in corrosive environments.

Switches have a digital display for easy monitoring at the source of your application.

Prevent changes to the set pressure that activates equipment—these switches come ready to use at your preferred setpoint.

Send two digital signals to your programmable logic controller (PLC) to trigger different processes—these switches activate at two set pressures.

These switches meet the pressure and electrical requirements of air compressors.

Sensitive to low pressures, these switches electrically activate automated controls or alarms when a set pressure is reached.

These medium-pressure switches electrically activate automated controls or alarms when a set pressure is reached.

At only 1 1/4" wide, these compact switches are a good fit for cramped spaces. They are often used in pump and hydraulic power applications.

Switches have a digital display for easy monitoring at the source of your application.

Built with an explosionproof enclosure to meet NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive liquids, dust, and gas are present.

Use in high-pressure applications up to 6,000 psi.

Change your setpoint with a twist of the outer ring.

Often used with ovens, dryers, and HVAC systems, these switches detect small differences in pressure.

These switches are rated NEMA 4 for protection from dirt and washdowns.

Change your setpoint with a twist of the outer ring.
