The LEVEL

SWITCH LS8111C******N*, LEVEL SWITCH LS8112C******N* are used for

monitoring or control of levels in hazardous areas, even for combustible liquids, gases, mist or

vapour.

The vibrating level switches LEVEL SWITCH LS8111C******N*, LEVEL SWITCH

LS8112C******N* are suitable for applications in hazardous atmospheres of all combustible

materials of explosion group IIA, IIB and IIC, for applications requiring instruments of category

1/2G or 2G.

2.1 Category 1/2G instruments

The electronics housing is installed in hazardous areas requiring instruments of category 2G.

The process connection elements are installed in the separating wall, which separates areas

requiring instruments of category 2G or 1G. The sensor with the mechanical ﬁxing element is

installed in hazardous areas requiring instruments of category 1G.

2.2 Category 2G instruments

The vibrating level switches LEVEL SWITCH LS8111C******N*, LEVEL SWITCH

LS8112C******N* are installed in hazardous areas requiring instruments of category 2G.

If the vibrating level switches LEVEL SWITCH LS8111C******N*, LEVEL SWITCH

LS8112C******N* are installed and operated in hazardous areas, the general Ex mounting

instructions as well as these safety instructions must be observed.

The installation of Ex systems must always be carried out by qualiﬁed personnel.
