Vehicle NVH testing solutions

Vibration of motors and powertrains for electric vehicle testing is characterized by high frequency content and the possible presence of current ground loops that can affect the accuracy of its measurement. Triaxial sensors such as the 8763B and 8764B offer an exceptionally broad frequency range and various ground isolation possibilities – all in a wide variety of g ranges, accommodating 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 motors and powertrains of electric vehicles.

Accurate vibration measurement on internal combustion engines and powertrains cannot compromise on excellent thermal performance, ease of mounting and resistance to harsh environments. This is why powertrain NVH engineers worldwide choose the triaxial IEPE accelerometers 8768A, 8766A and 8765A, which measure vibrations with accuracy nearly unaffected by temperature changes thanks to our proprietary PiezoStar crystal technology. Additionally, accelerometers 8768A and 8766A ensures flexible mounting and accurate calibration over all three axes, 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 8765A fits your requirements, as it features a through hole together with an integral ground isolation to minimize current ground loops.
When it comes to single axis measurements of engine and powertrain vibration, 8714B and 8715A deliver high termal performance. At the same time, they keep small dimensions, low weight and minimize ground loops thanks to the integral isolating pads.

Vehicle dynamics and durability testing often require measuring low frequencies down to 0 Hz, which is why customers worldwide measure with our highly accurate MEMS capacitive accelerometers 8316A and 8396A. These accelerometers can be configured to adapt any data acquisition chain and test environment, as they offer a wide choice of electrical output possibilities, including temperature and differential output, as well as various types of integral cables besides the standard connector. 
For electric vehicle testing,  the required operative frequency range might be broader. Triaxial accelerometer 8763B provides high accuracy and mounting flexibility, thanks to the three threaded holes, one on each direction. 
All these products well complement the Kistler vehicle dynamics, durability and tire testing product line.

For structural vibration measurement and modal analysis applications, triaxial sensors 8763B, 8788A and 8762A also offer a broad choice of g ranges and accurate vibration measurement, thanks to the low and ultra low noise levels. All ensure flexible mounting and accurate calibration over all three axes, thanks to the three threaded holes – one on each direction. 
Our product line for structural vibration and modal analysis is also complemented by an IEPE impluse hammer, impedance heads for shaker testing, cables and force sensors.
