    Abstract: The resistance detection sensor is configured to detect the electrical resistance value of a liquid. This resistance detection sensor includes a pair of electrodes, a DC voltage application unit, an AC voltage application unit, and a control unit. The pair of electrodes are immersed in a liquid. The DC voltage application unit applies a DC voltage having a first polarity between the pair of electrodes. The AC voltage application unit applies an AC voltage between the pair of electrodes. The control unit calculates the electrical resistance value of the liquid, in a state where the DC voltage is applied between the pair of electrodes by the DC voltage application unit. The control unit controls the AC voltage application unit so as to apply an AC voltage starting from a second polarity opposite to the first polarity at a predetermined time interval between the pair of electrodes. The time period for which the AC voltage is applied between the pair of electrodes by the AC voltage application unit is not an integer multiple of the cycle of the AC voltage applied between the pair of electrodes.

    Abstract: A method for operating an inductive conductivity measuring device that has a transmitting coil with an input and a receiving coil, the transmitting coil and the receiving coil being inductively coupled to one another by an electrically conductive medium. An electrical preset alternating signal is generated and fed to the input of the transmitting coil. The method for operating an inductive conductivity measuring device is improved in that a frequency of a preset alternating signal is varied in a frequency interval, in the frequency interval, a frequency-dependent minimum input impedance at the input of the transmitting coil is determined using a response alternating signal, a minimum frequency of the response alternating signal is determined at the minimum input impedance at the input of the transmitting coil, and a conductivity of the medium is determined using the minimum frequency of the response alternating signal.
