The new S220 two-component measuring hub from Kistler uses strain gauge technology to measure changes in tyre rolling resistance in very close proximity to the tyre footprint. The new measuring hub also allows static measurement of the contact force and control of the test stand. Unlike torque and power measurements of tyre rolling resistance, the force measurement method allows the S220 to minimise errors due to parasitic losses. Processing of the analogue data output optimises measurement precision on rolling resistance test stands by eliminating crosstalk. The new S220 is an addition to the RoaDyn range of measuring hubs used for high speed uniformity (HSU) tests, NVH studies, service life, quality and non-uniformity detection.
