Page 8: Functional Principle, Technical Data
Functional Principle, Technical Data Functional Principle, Technical Data Measuring Principle The capacitive distance measuring principle of the capaNCDT system is based on the functioning of an ideal plate capacitor. In the case of conductive targets, the sensor and the target located opposite form the two plate electrodes. If a constant alternating current flows through the sensor capacitor, the amplitude of the alternating voltage at the sensor is directly proportional to the distance between the capacitor electrodes. -

Page 12: Controller
Functional Principle, Technical Data 2.2.3 Controller The DT61x4 controller contains a voltage processor, oscillator, demodulator and an output stage. The voltage processor generates all required internal voltages from the supply voltage. The oscillator supplies the sensor with an alternating voltage that has a constant frequency and amplitude. The frequency is 31 kHz. The demodulator and output stage trans- form the measurement signal into a standardized voltage signal. -

Page 23: Scaling Of Measurements
RS485 Interface Measuring data consist of a counter, the packet length m and the measurements. The packet length m determines how many mea- surements are transmitted. The packet length m is the number of measurements that have been queried by the electronic system since the last time measuring data were queried, but is limited to the most recent 20 measurements. -
