摘要： A method for operating an inductive conductivity-measuring cell having a primary circuit with a sending coil, a secondary circuit with a receiver coil, and a short-circuit path, which passes through the sending coil and the receiver coil. The sending coil couples via the short-circuit path inductively with the receiver coil, wherein, in the case of closed short-circuit path, a first electrical signal present in the primary circuit is measured, and wherein the first signal is compared with, and/or weighed against, values, which are furnished or stored.

摘要： An inductively working sensor for determining the conductivity of a liquid medium. The sensor includes: at least one transmitting circuit, which is designed to deliver an input signal for a transmitting coil, in order to produce in the transmitting coil an alternating electromagnetic field, which causes a ring-shaped electrical current in the liquid medium; at least one receiving circuit, which is designed to evaluate a received signal produced by the ring-shaped electrical current in a receiving coil; a first coil; a second coil, which is arranged at a distance from the first coil; a switching means for switching between a first switch state and a second switch state, wherein, in the first switch state, the first coil, serving as transmitting coil, is coupled with one of the transmitting circuits; and the second coil, serving as receiving coil, is coupled with one of the receiving circuits, and wherein, in the second switch state, the second coil, serving as transmitting coil, is coupled with one of the transmitting circuits, and the first coil, serving as receiving coil, is coupled with one of the receiving circuits.
