Mobile app and vibration sensor

There are three key elements to SKF Enlight, the first of which is Data Collect, an app that turns a standard mobile device such as a smartphone or tablet into a data collection device. Data can be sent directly to the SKF cloud, for expert analysis by the global SKF Remote Diagnostic Centre (RDC) network. The second key element is the SKF Wireless Machine Condition Detector (WMCD), a special sensor that measures vibration and temperature data – and relays it to Data Collect via Bluetooth. The third element is specially built Atex Zone 1-compliant tablets and smartphones, if users need to collect data in hazardous areas.

"The app is extremely simple to use, allowing non-vibration experts to collect expert data,” says Christoffer Malm, head of Connectivity Room at SKF. "The user is only one button push away from RDC experts, who use their extensive knowledge to provide detailed analysis of a machine’s condition – and provide recommendations to rectify faults.”

The WMCD sensor, mounted magnetically to a machine, measures vibration and temperature data. This is then sent to the app – via Bluetooth – for visualisation. Vibration levels are benchmarked against ISO standards. The user sees the assessment as a simple ‘traffic light’ (red, amber or green) indicator.

In addition, the WMCD takes a simultaneous measurement of the bearing’s condition – using patented SKF algorithms to assess the severity of damage and wear. Again, results are displayed in traffic light format. In the event of a warning or alert in any of the measured parameters, the user can request an ‘On Demand Diagnostic’ directly from the measurement screen. Collected data is sent wirelessly to an SKF RDC, where a vibration expert can analyse the data and send a report as to the cause of the high vibration directly to the users email account.

Dedicated vibration analysers require a high level of competence, and are expensive for one-off measurements. SKF Enlight provides low-cost, easy to use instrumentation, with instant connection to SKF expertise through its RDC network. Manufacturing facilities and repair shops are likely to be the first beneficiaries.
