The intelligent KITAS sensors form a new generation of speed sensors. With the innovative crypto-graphical 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.
