DE 10 2007 008 004 B4

The Correvit S-HR sensors are an advancement of the proven
2-axis Correvit sensors and feature a high-resolution, lownoise angle signal.
•t Correvit S-HR with working range 250 ±50 mm, applicable
from 0,5 ... 250 km/h
•t Accuracy of the unfiltered angle within the range of ±15 °
is ±0,1 °
•t High-resolution slip angle measurement by enhanced
measuring principle
•t Adjustable filter time (unfiltered, moving average
8 ... 512 ms, FIR-Filter 2 ... 100 Hz)
•t Extremely high measurement accuracy, better than
±0,2 %, as a result of precise optics and digital signal
processing
•t Signal outputs: Analog, Digital, CAN-Bus, USB, RS-232C
Description
Correvit S-HR sensors measure slip angle and sideslip angle
with high dynamics and an exceptionally high measurement
accuracy.

CSHRA_000-806e-02.12

The patented enhancement of the well-known Correvit principle, the application of new optical components, and the latest
technology in digital signal processing enable the most precise
high-resolution slip angle measurement. 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 make the sensors especially suited for
measuring transversal vehicle dynamics like sideslip angle but
also tire slip angle when mounted on wheel.
The new Correvit S-HR sensors represent an essential contribution to the development of automotive measuring engineering.
Application
High-precision, slip-free measurement of distance, longitudinal/transversal speed and angle (high-resolution) for dynamic
vehicle testing, e.g. ISO 4138 steady-state circular-course
driving, ISO 7401 sudden steering angle change, tire research.
