Dual-Setpoint Electronic Pressure Switches with Digital Display


	4-Pole M12 Plug

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.

Dual-Setpoint Electronic Pressure Switches

Send two digital signals to your programmable logic controller (PLC) to trigger different processes—these switches activate at two set pressures. For example, you can turn on one pump to empty a tank when the pressure rises too high and another to fill the tank when the pressure drops too low. They could also be used to signal an alarm before switching off a pump. Twist the external rings to adjust each setpoint. Indicator markings and pointer make precise adjustments in the field easy. Avoid accidental changes to the setpoints by tightening the setpoint locking ring. Pair these switches with an M12 socket to quickly connect and disconnect them.

All switches are rated IP67, so they’re protected from dust and temporary submersion. UL and C-UL listed as well as CE marked, all meet U.S., Canadian, and European safety standards.

Electronic Flow Switches

When these switches reach a set flow rate, they send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms. Use the adjustment screw to select their set point. As flowing liquid pushes an internal piston, the switch reads the position of the piston to measure the flow. When the piston passes the set point, the switch actuates. They must be mounted horizontally to function correctly. IP rated, they withstand dust, washdowns, and temporary submersion.

These switches are calibrated with and measure water accurately. They can also be used with other liquids by applying your liquid’s specific-gravity conversion factor to calculate the new set point.

Electronic Insertion-Mount 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 position.

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

Sanitary Electronic Insertion-Mount 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. Use the buttons on the display to adjust the set point and other settings. They’re accurate in any mounting position.
