  Kistler Optical Sensors
The industry standard for vehicle dynamics testing

All Kistler optical speed/slip angle sensors have an unprecedented sampling rate of at least 250 Hz on every model!

Correvit non-contact optical sensors by Kistler represent the ultimate refinement in the evolution of measurement technology. Since the introduction of the world’s first optical speed and distance sensor in 1981, we have worked continually to bring increasingly high levels of accuracy and repeatability to the measurement of dynamic variables including speed, distance, angle and height.

  3-Axis Optical Measurement System
for measurement of speed, distance,slip angle and pitch/roll

The Kistler 3-Axis Measurement system uses three non contact laser ride height sensors of the HF-C series and one Correvit S-350 2-axis non contact optical speed/slip angle sensor to deliver precision measurement of vehicle pitch and roll, speed in two axis, slip angle, and yaw rate. This advanced measurement system is accurate on all test surfaces and maintains full measurement integrity, even on cambered and other non-flat surface planes.

Learn how the the Corrsys-Datron UC Processor delivers more accurate pitch and roll measurement than gyro platforms.

Non Contact Optical Height sensors
for measurement of vehicle ride height

  HF-250C - HF-500C - HF-750C
The non-contact Laser Height Sensors of the HF-C Series are optimized for the calculation of pitch and roll angles and allow for a nominal working range for passanger cars and trucks or SUVs.
These Sensors 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.





  The profile of the HF-xxxC sensor housing is shaped to match the the Correvit SF-II P Optical Sensor. This enables HF and SF-II P Sensors to be bolted together, as shown at right, for simultaneous use on a single mounting system. This enables the simultaneous measurement of tire slip angle and ride height relative to suspension travel.

UC Processor
The CAN-based UC Processor powers all of the Kistler height sensors that are used for Pitch & Roll measurement and also enables quick connection of a Correvit S-350 2-axis optical sensor with gyro in case you want to simultaneously measure slip angle from the vehicle center of gravity.

Information acquired by the sensors is calculated and transmitted via the UC Processor to a data acquisition system to provide an easy to handle Pitch & Roll System. An optional display enables you to view all measured data online.

  Camber Measurement System
For measurement of dynamic wheel camber

Using two HF Ride Height Sensors mounted on the vehicle wheel, accurate dynamic measurement of wheel camber relative to ground is at last a reality. This ingenious new system acquires dynamic wheel camber angle by comparing the relative change in height between the two sensors, as measured from the optical plane of each sensor to the surface of the road or track.
