LEXINGTON, KY (June 27, 2019) - Pressure losses in pneumatic systems can be costly and threaten machine efficiency. The new AVENTICS PE5 pressure sensor from Emerson measures systems losses and will alert when the leakage rate surpasses a pre-determined value. This enables excessive leaks to be identified early and addressed, before they become a major issue.
The sensor has two digital or one digital and one analog outputs. An IO-Link connection produces it simple to hook up to an Industrial Internet of Things (IIoT) network. The sensor can be included on new installations or easily added to an existing machine.
'Pneumatic system leaks can become a big issue for companies using lots of pressurized 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 planned, a local alert is set, and a transmission can be sent via the analog or digital outputs. The local alert consists of a adjust in display color from green to red. To trigger a maintenance task or to completely produce a work order, the analog and digital signals can be sent to a PLC or other network. The analog output can be turned between a current or voltage signal and the user has full control over the set points. The IO-Link connection offers more set up and diagnostic options. The local exhibit also shows how much faster the pressure has decreased than expected.
The PE5 is regarded for IP67 protection and mixes electronic precision with user-friendly versatility. The sensor boasts 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 offers precise display and switching information.
