Conductivity probe overview

In the LF measuring probe, four metal (rhodium) electrodes are aligned longitudinally and fused into the enamel coating of the probe carrier. Thermometer tubes, baffles or spacer rings may be used as probe carriers. The cell constant is dependent on the geometry and location of the probe and cannot be predetermined. For this reason, a four-wire circuit is used. A constant alternating current flows across the two outer electrodes and through the product. The resulting voltage drop is detected by the two inner electrodes and transmitted to a high-impedance measuring transmitter.
