Suspension Position
The position of suspension components can be measured Suspension
position: positive for bump (compression) and negative for rebound (droop).
Force
Force can be measured in suspension components or in aerodynamic
devices, such as spoilers and air dams. Force measurement is usually
achieved using load cells or strain gauges. The sensor should be calibrated
to read positive for compression and negative for tension.
Speed
The speed of the vehicle is very important as it is the prime input for
calculating distance travelled, creating track maps, allowing comparative
overlaying of different laps, analysing handling, etc. As such it is critical that
the sensor be solidly mounted, shielded from extreme heat and remote from
high currents and that the device it is sensing (normally a toothed wheel on
the back of the hub) be rigidly mounted, made from a magnetically soft
material (e.g. mild steel) and have extremely accurate spacing between
adjacent teeth.
