Detect the difference in pressure between two points. For instance, these switches can indicate a filter is clogged in a pump or cooling system.

Troubleshoot and monitor the difference in air pressure between two points—these switches have a dial indicator to show differential pressure in real time.

Tested and verified by UL and C-UL for use where explosive dust or gas are present, these switches have an explosionproof enclosure that meets NEMA 7 and 9 standards for hazardous locations. They are often used to indicate a filter is clogged in a pump or cooling system.

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

Maintain the air pressure needed for air-powered devices. These switches turn your electric air compressor off when it reaches the set pressure and on when it reaches the reset pressure.

When these switches reach a set pressure, they send electronic signals to your programmable logic controller (PLC) to activate automated controls or alarms.

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.

With multiple ports, these switches maintain the air pressure of your electric air compressor, while also including ports for up to three air-powered devices, reducing the complexity of your air system setup.

Trigger two different automated processes, each with their own set pressure.

Like other 3-A certified sanitary pressure switches, these switches trigger controls and alarms when food-processing, pharmaceutical, and biotech lines reach a set pressure, but they also have a sanitary adjustable setpoint ring that you twist to make quick changes.

When these switches reach either of their two set pressures—both of which can be controlled from a display—they send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms.

Kick off automated controls, signal alarms, or activate equipment based on pressure changes while checking the pressure, setpoint, and reset point on the display.

Often built into pumps and hydraulic systems with limited space, these compact switches power equipment, activate controls, and signal alarms when they reach a set vacuum.

Control the amount of vacuum change between when these switches activate and deactivate by adjusting when they reset.

Trigger two different processes in vacuum applications by sending signals to a programmable logic controller (PLC) when these switches reach one of their two set vacuums. They’re designed specifically for air systems.

Designed specifically for air systems, these switches send signals to your programmable logic controller (PLC) to activate controls or alarms when your system reaches a set pressure or vacuum.

With two setpoints and outputs, these switches trigger different actions in your system by sending signals to a programmable logic controller (PLC) when they reach one of their set pressures or vacuums.

For protection from dirt, washdowns, and corrosion, these switches have an enclosure that meets NEMA 4X.

An adjustment screw lets you alter the set point to suit your application.

These switches have a low-profile design to fit in water pipelines with limited clearance.

Alter the set point with the adjustment screw to suit your application.

For installation in environments with flammable gases and combustible dust, these flow switches are UL listed for use in hazardous locations.

Combine a foot-pedal actuator with a switching mechanism to build a complete switch.

Combine a push-button actuator with a switching mechanism to build a complete switch.
