The separable plastic submersible probe LMK
858 is designed for level measurement in most
aggressive media. Usage in more viscous media
as for example sludge is possible because of the
semi-flush diaphragm.
In order to facilitate stock-keeping andmaintenance the transmitter head is plugged to the
cable assembly with a connector and can be
changed easily.
