Abstract: The invention relates to a device (100) having multiple capacitively working channels, wherein the device (100) comprises a advancable sensor (3.1, 3.2) and a fluid container per channel. The device (100) also comprises a generator (G) for providing a periodic input signal (s,in(t)). In addition, the device (100) comprises one compensation circuit (CT.1, CT.2) per channel, which can be supplied with the periodic input signal (Sin(t)) and which is designed to provide an input signal (Sin1(t), Sin2(t)) at a first output (A.1, A.2) for applying to the sensor (3.1, 3.2) of the channel, wherein the compensation circuit (CT.1, CT.2) comprises a further output (6.1, 6.2) which is designed to provide a signal (s1(t), s2(t)) that can be evaluated to detect a phase boundary.

Abstract: A capacitively operating apparatus (100) has a container, a probe (3) movable into and/or out of the container, an input signal generator connectable to the probe (3) to provide an input signal (sin(t)) which produces at least one output signal (sout(t) in the probe (3), and a measuring apparatus (M) connectable to the probe (3) to tap the output signal (sout(t)) from the probe (3), and wherein the probe (3) is periodically chargeable and dischargeable, the output signal (sout(t)) corresponds to the time progression of a charging/discharging curve which is produced by the periodic charging and discharging of the probe (3). The apparatus (100) also includes a circuit module (10, 11) with two comparators for providing a first comparator output signal (PWM1) and a second comparator output signal (PWM2) from the output signal (sout(t)) and to correlate them with one another.
