CORRSYS-DATRON Optical Sensors
The industry standard for dynamic vehicle testing

All CORRSYS-DATRON Optical Speed/Slip Angle Sensors have an unprecedented sampling rate of 250Hz on every model!
CORREVIT® Non-Contact Optical Sensors by CORRSYS-DATRON 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, CORRSYS-DATRON has worked continually to bring increasingly high levels of accuracy and repeatability to the measurement of dynamic variables including speed, distance, angle and height.

In the arena of vehicle dynamics testing, CORREVIT® Non-Contact Optical Sensors have become the standard for measurement of vehicle handling and performance characteristics. Far surpassing the accuracy and reliability of the fifth wheel and other traditional measurement devices, CORREVIT® non-contact optical sensors are easier to set-up and easier to use. And because they do not make contact with road or track surfaces and have no moving parts, they resist damage and wear in even the most punishing testing applications.

In addition to their use in vehicle testing, CORREVIT® Non-Contact Optical sensors also prove to be highly effective for the measurement and control of rail vehicle speed, aerospace testing, industrial process measurement and consumer product testing. They are also ideally suited to a multitude of other applications demanding exceptional accuracy and rugged reliability.

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

S-350 Aqua
Like the L-350, the new CORREVIT® S-350 Aqua Sensor produces unparalleled accuracy, even under the most challenging conditions. Compact and lightweight, the S-350 Aqua Sensor 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. The S-350 Aqua Sensor is also available in a lighter-weight version optimized for racing applications.

Using the S-350 Aqua Sensor and Gyro, you can also 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:

Watch the video at the right which depicts the importance of accurate measurement of vehicle slip angle. Michael Henney of General Motors Corvette Racing Program tells us how important the optical slip angle sensors are to the development and refinement of the Corvette C6R. As with any vehicle testing it is imperative to have a highly dynamic sampling rate, which we bring you an unprecedented 250Hz on every model. With this in mind, you can be confident that you are capturing every dynamic maneuver

General Motors Corvette Racing Program

SF-II P
The SF-II P sensor is 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 SF-II P delivers exceptional accuracy in slip angle measurement. Due to its compact size, this world-class sensor has been integrated into compact and low profile packages by many major automotive manufacturers and suppliers. The SF-II P sensor 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 CORRSYS-DATRON 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.

hf750

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 CORRSYS-DATRON 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-Box 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 CORRSYS-DATRON HF-xxxC 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.
