HF-250C
HF series use the principle of optical triangulation. A visible red laser is focused onto the road surface. Reflected light is collimated onto a linear CCD array. The distance to the object is calculated from the position of the light spot on the CCD array. The output of the sensor is directly proportional to the measured height.| Performance Specifications | Unit | HF-250C |

| • | Height-sensors for measuring e.g. pitch and roll angle according to ISO 4138 (steady-state circular-course drive). |
|---|---|
| • | Further fields of application are for instance uplift measurements, spring deflection, dynamic tire flat spotting, tire lift-off (Fishhook Test). |
| • | Two HF sensors mounted at the wheel enable dynamic camber angle measurement (refer to Kistler DCA System). |
