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.

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.

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. All meet at least one American, Canadian, or European safety standard.

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. Choose anywhere within the setpoint range for your reset point.

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.

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.

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 position.

IP65 rated switches protect against dust and washdowns. IP67 rated switches withstand temporary submersion.

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.
