Accelerometers

Vibration sensors use solid-state piezoelectric accelerometers to detect the level of vibration in rotating elements like bearings and gearboxes on machinery such as motors, generators, pumps, fans and compressors. Regular vibration measurements on all critical machines as part of the maintenance regime can detect early signs of failure and provide a way to eliminate these problems. Bearing wear, poor balance and loose mounting all lead to the failure of rotating machinery. Unexpected machinery failure leads to unplanned maintenance costs, loss of production plus potential Health and Safety hazards. They are rugged, adaptable to all types of machinery and conditions including operation in hazardous areas, easy to install and require no maintenance. Used in conjunction with off- and on-line vibration analysers they yield valuable diagnostic information on the machinery's condition and reveal where and when failure may occur allowing pre-emptive maintenance intervention. The dc (velocity) outputs integrate this complex signal into a simple dc signal of 4-20mA proportional to the overall vibration of the machine, ideal for monitoring with all types of industrial controllers.
