NIVOCONT K conductive level switches are ideal for use in liquids with conductivity above 10 μS/cm. These switches detect liquid levels using a probe immersed in the medium. Available in single and multiple rod types, the probes and the conductive tank wall (if applicable) act as electrodes, with the liquid serving as the conductive material between them. Multiple-probe sockets can accommodate up to four rods, plus an additional reference probe if the tank wall is non-conductive. The probe length must match the measured level. When the liquid reaches the probe, it alters the loop's conductivity, activating the output relay. The device detects changes in conductivity between the probes and the reference probe. KLP separators should be used every 0.5 meters to maintain proper distance between the probes.
