The intelligent KITAS sensors form a new generation 
of speed sensors. With the innovative crypto-graphi-
cal IC the gear-box signals can be transmitted  
tamper-proof without an armoured cable for the first 
time.
A dynamic element converts the revolution of an  
impulse- or gear wheel into electrical signals.
In parallel to the encrypted revolution data the  
conventional real-time signal is also available. 
Through a comparison of these two sources the  
tachograph can detect data manipulations safely. 
Therefore the KITAS sensor and the tachograph form 
an authorised system.
A link between the serial numbers of the KITAS  
sensor and the tachograph enchances the security 
even further.
