‘Wear and tear’ sensor by 2010

Sensors that predict when mechanical parts will break down could be introduced by 2010. Such a sensor would slash maintenance costs across the manufacturing industry. Scientists at the University of Manchester and other European universities are developing a new type of wireless sensor that will remotely monitor mechanical parts and systems. The device would fit inside gearboxes, motors, diesel engines, wheel bearings and other mechanisms in which faults can occur. Once fitted, the sensors would allow remote monitoring of the ‘health’ of the parts. The data would predict when parts must be serviced or replaced. Andrew Starr, who will lead the Manchester side of the European-wide project, commented: “By monitoring the condition of major parts, we will be able to predict when they require maintenance and when they need replacing before they fail. This will reduce the delay and cost caused by break downs.” Manchester will develop a Mems sensor to measure a range of parameters including vibration, temperature and pressure. Another application will be inside lubricated machinery, measuring concentrations of metallic elements created through wear and tear – from which the life span of the part could be calculated. The sensor will be developed as part of a £4.1 million initiative funded by the European Union under Framework 6, known as Dynamite, to advance knowledge in e-maintenance and condition monitoring.
