Electrodes work according to the conductive principle in connection with filling level controllers ( see chapter 1011 ). When the electrodes are immersed into an electrically conducting liquid, a control current will flow through the liquid. Via a measuring amplifier a switching contact will be activated by the controlling current. The current circuit is galvanically isolated from the mains and is operated by protective extra-lowvoltage. In order to avoid an electrolytic effect on the electrodes, they are operated with alternating voltage.
