Vibration of electric motors and powertrains is characterized by high frequency content and the presence of current ground loops that can affect the accuracy of its measurement. In this context, triaxial sensors such as the 8763B and 8764B offer an exceptionally broad frequency range and various ground isolation possibilities – all in a wide varity of g ranges, accomodating several NVH testing scenarios. Additionally, accelerometer 8763B ensures flexible mounting and accurate calibration over all three axis, thanks to the three threaded holes - one on each direction. If you need 360° freedom for cable orientation and maximal connection stiffness via screw mounting, accelerometer 8764B fits your requirements, as it features a through hole together with integral ground isolation to minimize current ground loops.
When a single axis measurement is preferred, sensors 8704B and 8774B offer the right performance with a variety of options to optimize your NVH testing on electric motors and electric powertrains.
