One N2 Gateway and 43 PI units were installed. The equipment delivers remote monitoring of the belt cleaner blade status on mobile devices via the proprietary Martin Smart Device Manager App. Communicating through the gateway, the technology uses sensors to indicate remaining blade life, notifying technicians and operations personnel when re-tensioning or replacement is required. The PI maximizes the blade’s usable surface area and reports with certainty when a blade is nearing the end of its useful life. It will also collect data and provide information on any belt cleaner utilizing a Martin blade. ### Results ![SingletonPSP_Results](https://blog.martin-eng.com/hs-fs/hubfs/SingletonPSP_Results.jpg?width=420&height=315&name=SingletonPSP_Results.jpg)Maintenance planning was simplified with detailed on-demand information available, allowing technicians to focus immediately on problem areas and install replacement wear parts as needed. The result was a dramatic increase in efficiency and a 50% reduction in site visits, [saving money on labor and improving safety](https://blog.martin-eng.com/is-there-an-app-for-that) through reduced exposure to equipment, offering a quick and calculable ROI. "The N2 is a clever piece of kit that's safe, saves time, and is easy to use,” said Stuart Howden - Engineering Manager of Singleton Birch. With additional data, the facility also developed a plan to service secondary cleaners when an alert is received on primary cleaners to further enhance efficiency.
