Electronic Pressure Switches for Compressed Air
With a set pressure range that works for most air systems, these switches send signals when your air system reaches a set pressure to your programmable logic controller (PLC) to activate automated controls and alarms. All meet at least one American, Canadian, or European safety standard.
Monitor your pressure 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 pressure change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point.
Switches with a configurable output give you the flexibility to choose between PNP, NPN, or IO Link. IO Link lets you remotely control and monitor switches from your PLC or PC when you connect an IO Link controller (not included).
IP65 rated switches protect from dust and light rinsing.
Add a square panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

Dual-Setpoint Electronic Pressure Switches with Digital Display
When these switches reach either of their two set pressures—both of which can be controlled from the display—they send digital signals to your programmable logic controller (PLC) to activate automated controls. This means you could turn on a pump at one setpoint if pressure drops too low and open a valve at another if pressure rises too high. These switches could also be used to signal an alarm before switching off a pump. For remote control and monitoring from your PLC or PC, connect an IO Link controller (not included). You’ll also need to set one of the outputs to use IO Link instead of a PNP or NPN signal.
Change your setpoint, reset point, scaling, and other settings using the display’s 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. The head rotates, so you can view the display from the best angle. To reduce stress on pipes in your pressure system, secure these switches against a wall or other structure with a mounting bracket (sold separately). Use these switches with an M12 cable (sold separately) to quickly connect and disconnect them.
All are rated IP65 and IP67, so they seal out dust and water from washdowns and brief submersion. UL and C-UL listed, all meet U.S. and Canadian safety standards.

Kick off automated controls, signal alarms, or activate equipment based on pressure changes while checking the pressure, setpoint, and reset point on the display. The adjustable reset point lets you control the amount of pressure change, also known as deadband and differential, before the switch resets. Adjust it anywhere within the setpoint range. Turn the external adjustment knob by hand to set pressure quickly. These are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed).
To power the display, these switches need a separate electrical input from the one used for switching.
These switches are IP and NEMA rated, so they’re dust tight and protected against water from washdowns and weather, as well as sprays of oil and coolant.

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.

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.

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications. Also known as transducers, they measure the difference in pressure between two inputs and convert it to electrical signal. Connect them to your programmable logic controller or receiving device to monitor differential pressure remotely, activate automated controls, or trigger alarms when they reach the set pressure. A digital display lets you monitor the differential pressure and troubleshoot issues at the source. It rotates for readability.
You’ll often see these transmitters used to indicate a clogged filter or help maintain a certain pressure in HVAC systems, pumps, and cooling systems. NEMA and IP rated, they protect against dirt, dust, corrosion, weather, washdowns, and temporary submersion.
For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. As differential pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.

Electronic Insertion Flow Switches
Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter (sold separately) and insert them into a pipe tee or pipe outlet. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. These switches are accurate in any mounting orientation.
IP65 rated switches protect against dust and washdowns. IP67 rated switches withstand temporary submersion.

Sanitary Electronic Insertion Flow Switches
Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.
They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures.
