LNK-K Conductive Level Switch

Brand: KOBOLD Instruments, Inc.

The conductive KOBOLD level probes LNK-K are use for level measurement. The electrical resistance between metallic vessel and level electrode is measured and evaluated. In combination with the KOBOLD LZE or LZE-R weld-in sleeves, the probe provides a measuring point that has no dead space and meets hygiene standards.

This level switch is therefore very well suited for CIP/SIP cleaning and because of its compact design the device is suitable for almost every measurement. The KOBOLD probes LNK-K are also available with integrated evaluating electronics. The output signal (24 V DC) can thus be connected to a PLC for evaluation.

This means lower installation costs, minimum wiring requirements and a high degree of noise immunity. The level probes are connected electronically through an M12x1 plug connection. Different stem lengths are available. The stem may also be E-CTFE coated, so that foaming media can be detected.
