“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. 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.
