The conductive KOBOLD level probes LNK together with the transducer for head mounting are used for level measurement. This method is based on the evaluation of the electrical conductivity of the medium. In combination with the KOBOLD LZE (p.119-124) or LZE-R (p. 125-128) weld-in sleeves, the probe provides a measuring point that has no dead space and meets hygiene standards and (EHEDG approval certificate). This level switch is therefore ideally suited for CIP/SIP cleaning. The level switch is available with 1 or 2 - 4 electrodes, also available with E-CTFE coating. This allows foaming media to be detected reliably. The output signal from the probes with head mounted transmitter can be connected directly to a PLC for evaluation. This means lower installation costs, minimum wiring requirements and a high degree of noise immunity. The divice is available with an optional M12 x1 plug connector
