Our customer was looking for ways to improve efficiency and reliability, and reduce operation costs and overheads for their manufacturing facility. The initial step in this transformation was to add additional monitoring and measurements to several areas of their facility to allow the collection of usage data from older machinery for analysis. The machinery to be analysed would be located in many areas of the complex, with some sitting in concrete outbuildings far from the source of the main network.
