Correvit® SFII Sensors

Type CSF2A...

Non-Contact Optical Sensors

Patent No. DE 43 13 497 C2

The Correvit SFII sensors are designed for racing applications
to measure longitudinal and transversal speed.
•t Developed for measurement of tire slip angle from
0,3 ... 250 km/h; Racing version with speed range
0,3 ... 400 km/h available
•t Small and lightweight – just 250 g
•t Adjustable filter time (unfiltered, moving average
8 ... 512 ms)
•t Measurement accuracy <±0,5 %
•t Improved features by application of advanced DSP technology
•t Signal outputs: Analog, Digital, CAN-Bus or RS-232C
Description
Correvit SFII sensors represent an advanced development
of the Formula-1 proven Correvit SF sensor, with its longlife, vibration-resistant infrared LED illumination. Consistent
miniaturization and a low weight enable universal mounting
positions, e.g. below the vehicle near the center of gravity. The
applied state-of-the-art technology provide improved performance, even under harsh environmental conditions.
Equipped with 4 analog and 4 digital outputs, SFII sensors
permit simultaneous measurement of longitudinal, transversal,
and magnitude speed, as well as angle measurement. Complemented with high-speed data transfer via CAN Bus, RS-232C,
or USB, the SFII sensors can be used with any current data
acquisition system.

CSF2A_000-812e-01.12

A protective optical-glass lens prevents damage to the optics
and the illumination source and can be easily replaced without
use of special tools.
Application
High-precision, slip-free measurement of distance, longitudinal and transversal speed as well as angle for vehicle dynamics
testing.
