A new window to route- based condition analysis


and MIL-STD-810G certification for operation virtually anywhere. The use of wireless sensors and measurement modules is said to make setup of the Maintenance Pad quick and safe without cables and minimises the time

route-based condition monitoring data collector and analyser from Metso uses IP65


spent close to the machine being measured. Sensors have built-in memory and can even be left in the field, logging data for later download. The Maintenance Pad is a


fully-functional industrial tablet computer with Metso Machine Analyser software that includes route planning, route and off- route measurements as well


as efficient tools for vibration analysis. Microsoft Windows provides a

familiar platform for the operator as well as enabling the use of commercially available software. The standard WLAN capability of the tablet used with the wireless sensors is supplemented by Bluetooth, while a barcode reader and camera further expanding the flexibility. The collected vibration data is stored directly on the Machine Analyzer database by means of a built-in 128 GB solid state memory. Historical data is available for immediate analysis during route measurements with vibrations easily analysed in the field on the sunlight-viewable 10.1-inch touch screen. Collected data can also be synchronised with Metso’s on-line condition monitoring systems and other computer data bases.


Automated capping valves for Stora Enso Nymölla mill


Stora Enso Fine Paper’s Nymölla mill in Sweden has ordered new capping valves from Metso for its batch digester line 1. Five Neles PZ-series capping valves will replace the mill’s old hydraulic cappers, enabling Stora Enso to improve productivity by automating its digesters, which previously required manual assistance in the chip filling phase. The Neles PZ series of capping


valves improve process safety, enhance process reliability and

eliminate unscheduled process downtime. Design features, like a preloading device mounted outside the valve body, prevent chips and liquor from causing hazards. Special interlocking systems, essential to plant safety, help lower maintenance costs. The batch cooking process at the Nymölla mill presented a demanding challenge because magnesium bisulfite is used as a cooking liquor. To meet this requirement a number of


technical changes were made to the standard Neles PZ-series capping valve design. With two paper machines, the Nymölla mill specialises in producing high quality office papers. It has an installed base of around 1,000 valves supplied by Metso along with an IQ


Using wireless sensors and measurement modules makes setup quick and safe without cables and minimizes the time spent close to the measured machine


Benefits include: reduced unnecessary downtime; early prediction of failure; planning of machinery repairs well in advance; evaluation of critical process machinery condition; forecasting of the remaining operational life of equipment; wireless sensors improve safety during route-based monitoring.
