LNZ Capacitive Level Switch

Brand: KOBOLD Instruments, Inc.

The KOBOLD LNZ capacitive level switch is used for detecting levels of fill. The electric field penetrates several millimetres into the medium.

The change in capacity caused by contact with the medium is measured and evaluated. By using this principle of measurement it is also possible to detect non-conductive media. Installation in tanks is very straightforward regardless of position.

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. Installation is virtually front-flush. This level switch is therefore very well suited for CIP/SIP cleaning.

Adapter sleeves are also available for different process connections so that the device can also be used in existing systems. Because the electronics are already integrated no other evaluating instrument is necessary.

The output signal (24 V DC ) can therefore be transmitted direct to an SPS for further processing.
