Accelerometers For Wind Turbine Applications
NEW PRODUCT PRESS RELEASE
20th April 2010
For Immediate Release
ACCELEROMETERS FOR WIND TURBINE APPLICATIONS
The established range of SENSONICS PZS accelerometers have been extended to provide a vibration monitoring solution for wind turbine applications. The proven shear mode constructed PZS accelerometer series have been supplied for many applications, including wind turbine monitoring over the past 5 years. This enhancement of the product range 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. This is important as it’s an industry requirement for wind turbine condition monitoring systems.
As with any rotating machinery in a critical application the monitoring of vibration plays an effective role in the early detection of mechanical problems on the machine. The PZS accelerometer response is suitable for measuring vibration across the full wind turbine machine train. This is for not only the low frequency front end, but also 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. ENDS.
