Kistler Optical Sensors
The industry standard for dynamic vehicle testing

All Kistler optical speed/slip angle sensors have an unprecedented sampling rate of 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.

2-Axis Non Contact Optical Velocity & Slip Angle Sensors
for measurement of longitudinal and transversal dynamics

Correvit S-350 Aqua Sensors
Like the L-350 sensors, the S-350 Aqua sensors produce unparalleled accuracy, even under the most challenging conditions. Compact and lightweight, the S-350 Aqua Sensors can be mounted in seconds. Our patented Correvit two-axis sensors utilize advanced optical structures, high-speed DSP/FPGA processing and filter networks to provide uncompromised precision, regardless of the testing environment. S-350 Aqua sensors are also available in a lighter-weight version optimized for racing applications.

Using a S-350 Aqua sensor and gyro, you can simultaneously measure slip angle from the vehicle center of gravity To learn more about how you can use this powerful new sensor system to accurately measure slip angle, please view our informative application report:

S-HR Sensors
Correvit; S-HR sensors measures high-resolution slip angle and sideslip angle with high dynamics and an exceptionally high measurement accuracy. True 250 Hz signal update rate tracks every high dynamic maneuver.
Due to the new operating principle (absolute measuring) the angle signal is very low-noise which provides maximum dynamic performance of the angle signal without further signal filtering. This advantage makes the S-HR sensors especially suited for measuring transversal vehicle dynamics like sideslip angle but also tire slip angle when mounted at the wheel.

SFII Sensors
Correvit SFII sensors are designed for racing and vehicle dynamics measurement applications that demand high performance in an ultra-lightweight package. A favorite on the F1, NASCAR, IRL, AMLS, and DTM racing circuits, the SFII sensors deliver exceptional accuracy in slip angle measurement. Due to the compact size, this world-class sensor has been integrated into compact and low profile packages by many major automotive manufacturers and suppliers. The SFII sensors enables simultaneous measurement of longitudinal, transversal and magnitude speed, as well as angle, and is the only way to accurately measure tire slip angle.

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.

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.

HF-Sensor

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.
