Pressure and Vacuum Monitoring and Control

Pressure Transmitters

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

Economy Pressure Transmitters

Choose these transmitters when you need reliable pressure monitoring but not high accuracy.

Pressure Transmitters with Digital Display

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

Flush-Mount Pressure Transmitters

The diaphragm on these transmitters mounts flush with your system’s connection, leaving no room for thick liquids to clog or harden. They’re often used to monitor pressure in wastewater, paint, and adhesive-dispensing applications.

Pressure Transmitters for Compressed Air

With a pressure range common to most compressed air systems, use these transmitters to monitor your system's air pressure.

Pressure and Vacuum Transmitters with Digital Display

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

Pressure and Vacuum Transmitters for Compressed Air

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum.

Remote Displays for Pressure Transmitters

Monitor pressure in your system from a distance by using this display in conjunction with pressure transmitters.

Digital High-Accuracy Pressure Gauges

A digital display allows for easy reading of measurements.

Hand-Held High-Vacuum Gauges

Check the vacuum levels in high-vacuum pumps, valves, and chambers with this compact gauge.

Digital Pressure and Vacuum Gauges

A digital display allows for easy reading of measurements.

High-Accuracy Digital Test Gauges for Pressure

Gauges have an accuracy of ±0.25%.

Ultra-High-Accuracy Digital Test Gauges for Pressure

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges.

Force Sensors

Tension and Compression Force Sensors

Also known as load cells, these sensors measure and track the forces of your equipment by converting them into electrical signals.

Robot-Ready Force Torque Sensors

Mount these sensors between a robot arm and a tool for precise control during delicate tasks, such as sanding or assembling small parts.

Electric Ultra-High-Vacuum Pumps

Achieve vacuum levels up to 1 x 10 ^-12 torr with these ultra-high-vacuum pumps.
