Electronic Vacuum Switches for Compressed Air
Specifically made for air systems, these switches send signals to your programmable logic controller (PLC) to trigger processes when they reach a set vacuum. Use them to turn equipment on or off, activate automated controls, or signal alarms. Check the vacuum on the display and change your setpoint, reset point, scaling, and other settings using the buttons. An adjustable reset point means you can control the amount of vacuum change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point. All switches meet at least one American, Canadian, or European safety standard.
Add a square panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Dual-Setpoint Electronic Vacuum Switches for Compressed Air
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. Designed specifically for air systems, they can turn on a vacuum pump if the vacuum is too low or a valve if the vacuum is too high. Or use them to signal an alarm before switching off a pump. Check the vacuum on the display and change your setpoint, reset point, scaling, and other settings using the buttons. An adjustable reset means you can control the amount of pressure change before the switch resets. This pressure difference is commonly referred to as deadband and differential. Choose anywhere within the setpoint range for your reset point.
Rated IP65, these switches seal out dust and water from light rinses. They meet American, Canadian, and European safety standards since they’re UL and C-UL recognized components as well as CE marked.
Add a square panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Monitor pressure, setpoint, and reset point on the digital display. Use the display’s buttons to change your settings. These switches have an adjustable reset point (also called adjustable deadband or differential), so you can control the amount of pressure or vacuum change before the switch resets.

Dual-Setpoint Electronic Pressure and Vacuum Switches for Compressed Air
With two setpoints, these switches trigger different actions in your air system by sending signals to a programmable logic controller (PLC) when they reach one of their set pressures or vacuums. For example, they can activate one light when a system is pressurized and another when it’s under vacuum. They have an adjustable reset, so you can control the amount of pressure change before the switch resets. This pressure difference is also called deadband or differential. Choose a reset point anywhere within the setpoint range.
Easily monitor your pressure or vacuum setpoint on the digital display. Use its buttons to adjust the settings and setpoint.
These switches are rated IP65 to seal out dust and water from light rinses. They’re CE marked, UL and C-UL recognized components, and CSA certified to meet American, Canadian, and European safety standards.

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.
Transmitters with current output connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.
Transmitters with voltage output 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.
Add a panel-mounting bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.
