Controller
The capaNCDT 6110/6120/IP contains a voltage processing, oscillator, integrated preamplifier, demodulator
2
as well as an output level.
The voltage processing produces all necessary internal voltages from the power supply. The oscillator sup-
plies the sensor with frequency and amplitude-stabilized alternating voltage. The frequency is 16 kHz. The
internal preamplifier generates the distance-dependent measuring signal and amplifies it. Demodulator and
output level convert the measuring signal into a standard voltage signal
3
.
The output voltage can reach up to a maximum of 13 VDC when sensor is disconnected or measurement is
exceeded.
