PicoDiagnostics NVH kits

Pico's products for Noise, Vibration and Harshness (NVH) testing give technicians the ability to identify and diagnose unwanted vibration and noise sources in a vehicle.

Balancing propshafts with PicoDiagnostics NVH kit

The PicoDiagnostics NVH kits can also support balancing of rotating components when you use the optional Optical Sensor kit with it. 

The NVH kits can reveal problems with vibrations that are related to engine speed (RPM), propshaft speed, road speed or other unrelated frequencies. With the example of a propshaft-related vibration, it can be a lot faster and cheaper to rebalance the propshaft than to replace it.

The balancing kit contains a high-quality optical sensor with an interface to connect it to your PicoScope, and a robust magnetic mount to ensure that the optical sensor can be held in the correct position. Again, the software wizards in PicoDiagnostics will guide you through every step of the process.

The Balancing software supports different methods such as the use of pinion flanges (adding weights to existing holes in the flange), and hose clamps (clamping weights to the shaft using jubilee clips). In each case, the system provides complete guidance and direct instructions on both the weight and location to balance the shaft.

Together with an NVH kit, this system brings the technician a level of capability previously only available in the vehicle manufacturer's factory or expensive and dedicated repair facilities. All of this is supported by our ongoing software updates, which will continue to improve the system long after an initial purchase.
