Accelerometer covers full frequency response requirements of wind turbine power transmissions
22 April 2010
The Sensonics PZS accelerometer range has been extended to provide a vibration monitoring device for wind turbine applications. The shear mode constructed PZS now provides a frequency response down to 0.1Hz and permits effective monitoring of both the wind turbine main shaft and input gearbox bearings below rotational speeds of 20rpm - an industry requirement for wind turbine condition monitoring systems.

The Sensonics PZS accelerometer range has been extended to provide a vibration monitoring device for wind turbine applications. The shear mode constructed PZS now provides a frequency response down to 0.1Hz and permits effective monitoring of both the wind turbine main shaft and input gearbox bearings below rotational speeds of 20rpm - an industry requirement for wind turbine condition monitoring systems. As well as the low frequency front end, the PZS response is also appropriate for the planetary gearbox stages and generator, providing an upper frequency response in excess of 10kHz.
The shear mode sensor is electrically and thermally isolated from the main accelerometer housing, minimising the effect of electrical interference on the measured signal and the impact of thermal changes, which can result in base strain effects. These are key factors to the successful implementation of low frequency accelerometers.
Available in straight and side exit mechanical configurations with mounting threads to suite most applications, the PZS is supplied with either a 2-pin connector or integral cable, offering protection up to IP68.
