Pressure Switches for Air Compressors

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. All are NEMA rated to protect their parts from dirt and stand up to some corrosion, but they shouldn’t be used outdoors. UL listed and CSA certified, all meet American and Canadian safety standards. Those that are CE marked meet European safety standards.

Pressure Switches with Air Exhaust Valve

Switches with an air exhaust valve release the air between the cylinder and check valve when the compressor shuts off, reducing stress on the compressor’s motor. This extends the life of the motor and makes for an easier startup each time.

Multiport Pressure Switches for Air Compressors


Pressure Switches with Air Exhaust Valve	Pressure Switches with Air Exhaust Valve and Manual On/Off

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. These switches turn off the compressor when it reaches the set pressure and on when the pressure drops to the reset point. They have an air exhaust valve, so when they shut off, they automatically release air between the compressor’s cylinder and check valve. This reduces stress on the motor to extend its life and makes for easier startups. All are NEMA rated to protect from dirt and stand up to some corrosion, but they shouldn’t be used outdoors. UL listed, CSA certified, and CE marked, they meet American, Canadian, and European safety standards.

Dual-Setpoint Electronic Pressure Switches for Compressed Air

Compatible with most air systems, these switches send digital signals to a programmable logic controller (PLC) to trigger separate processes when they reach either of their two set pressures. For example, they’ll activate a compressor if the pressure is too low or a relief valve if the pressure is too high. Or use them to signal an alarm before switching off a compressor. Some of these switches also work with liquids and gases, so they can be built into hydraulic systems and wet or humid environments, such as cleaning lines.

Monitor your pressure on the display and change your setpoints, reset points, scaling, and other settings using the buttons. An adjustable reset point means you can control the amount of pressure change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point. Add a panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Rated IP65, they seal out dust and water from washdowns. Switches are UL and C-UL recognized components and CE marked to meet American, Canadian, and European safety standards.

Pressure and Vacuum Transmitters with Digital Display

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display. These transmitters, also called transducers, have two outputs, so you can program them to work as a transmitter, a switch, or both. When they reach their setpoint, they send electrical signals to your programmable logic controller (PLC) to trigger actions in your system. Adjust their reset point anywhere within the setpoint range. To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You need an IO-Link controller (not included) to connect to your interface.

Buttons on the display let you change your setpoint, measuring range, and other settings. To quickly tell the status of your process, you can program the color of the display to red and green. LEDs on the corners also notify you of your output’s switching status. Rotate the head to view the display from the best angle.

You must calibrate your PLC in order for it to interpret signals from these transmitters. As pressure increases, the output signal from the transmitter will increase. These transmitters only give accurate readings within the rated pressure or vacuum range.

All have an M12 plug to connect to M12 Connectors. When using both switching outputs and an IO-Link controller, they require four wires to connect. For their 4-20mA analog output, they need two wires to connect. View switch wiring diagrams by selecting a part number and clicking Product Detail.

To withstand wet environments, these transmitters have a 316L stainless steel connection and are IP rated. Their IP ratings also mean they’re dust tight and stand up to spraying water and brief submersion. UL and C-UL listed as well as CE marked, they meet strict American, Canadian, and European safety standards.

Pressure and Vacuum Transmitters for Compressed Air

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum. Also known as transducers, they convert both pressure and vacuum into an electrical signal that can be interpreted by receiving devices, such as remote displays, and motor speed controls. They also have two digital PNP switch outputs that you can connect to your programmable logic controller (PLC) to activate automated controls or alarms when a set pressure or vacuum is reached. Change settings with the buttons on the digital display.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's pressure or vacuum range and output signal. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure or vacuum range.

UL and C-UL recognized components, CSA certified, and CE marked, they meet American, Canadian, and European safety standards.

Wire Leads

4 mA to 20 mA Output Signal—Transmitters with 4 to 20 mA output signal connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Signal is not lost over long distances and isn’t affected by electrical interference from other devices.

1V DC to 5V DC Output Signal—Transmitters with 1 to 5V DC output signal connect using three wires. Two wires connect to the power supply, and a separate wire sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.
