3.2 Intended use
Magnetostrictive level transmitters are used exclusively for the continuous measurement of
the level of liquid media in vessels.
The level transmitters are designed as intrinsically safe equipment and are suitable for use
in hazardous areas. All level transmitters can be used for all gases of group IIA, IIB and IIC.
In addition, all level transmitters may be used for the dust groups IIIA, IIIB and IIIC.
If a non-conductive plastic float is to be used in hazardous areas with gases of group IIC,
the danger due to static charging must be prevented. Observe the following conditions:
■
The float must not be used in strongly flowing, non-conductive liquids.
■
There must be no stirrer in the tank.
■
Frictions on non-conductive components must be avoided.
■
The float must not be cleaned dry.
