ABSTRACT:
An inductive conductivity sensor is immersed in a liquid to measure its conductivity. The sensor comprises a transducer for generating a changing magnetic field and for inductively measuring an electric current induced in the liquid by the changing magnetic field. The transducer has an external surface facing the liquid. A elastic membrane separates the external surface from the liquid. The elastic membrane is periodically inflated and deflated to deform its outer shape and thereby remove deposits formed on the membrane.
