IIoT-enabled pressure sensor reduces costly pneumatic system losses

Pressure losses in pneumatic systems can be costly and affect machine efficiency. The new Aventics PE5 pressure sensor from Emerson measures systems losses and will alert when the leakage rate exceeds a pre-determined value. This enables excessive leaks to be diagnosed early and addressed, before they become a major issue.

Emerson AVENTICS PE5 Pressure Switch IIoT-enabled pressure sensorThe sensor has two digital or one digital and one analog outputs. An IO-Link connection makes it simple to connect to an Industrial Internet of Things (IIoT) network. The sensor can be used on new installations or easily added to an existing machine.

“Pneumatic system leaks can become a major issue for companies using lots of compressed air,” said Dieter Michalkowski, IIoT specialist with Emerson’s machine automation business. “Excessive leakage can lead to the need for larger compressors, or compromised machine performance. This new sensor addresses that issue in a simple and easy to implement way.”

When the machine is switched off, the Aventics PE5 sensor measures pressure loss over time. If the pressure drops faster than desired, a local alert is set, and a signal can be sent via the analog or digital outputs. The local alert consists of a change in display color from green to red. To trigger a maintenance task or to automatically generate a work order, the analog and digital signals can be sent to a PLC or other network. The analog output can be switched between a current or voltage signal and the user has full control over the set points. The IO-Link connection offers additional set up and diagnostic options. The local display also shows how much faster the pressure has dropped than expected.

The PE5 is rated for IP67 protection and combines electronic precision with user-friendly versatility. The sensor features simple switching between current and voltage, and between PNP, NPN and push-pull. This flexibility allows the PE5 to be used in a wide range of applications. No matter the environment, with the zero-point offset function the pressure sensor can be set to zero at any time and thus provides exact display and switching information. Pneumatic connections include G1/4 or 4 mm push-in.
