Agitators

Enamel coating

Gas-tight leadthrough

*7ML19985KY01*

Due to the effects of agitators, equipment vibration or similar, the

level switch can be subjected to strong lateral forces. For this reason,

do not use an overly long extension tube for SITRANS LVL200E, but

check if you can mount a short level switch on the side of the vessel in

horizontal position.

Extreme vibration caused by the process or the equipment, e.g.

agitators or turbulence in the vessel, can cause the extension tube of

SITRANS LVL200E to vibrate in resonance. This leads to increased

stress on the upper weld joint. Should a longer tube version be neces-

sary, you can provide a suitable support directly above the tuning fork

to secure the extension tube.

This measure applies mainly to applications in Ex areas category 1G

or WHG. Make sure that the tube is not subject to bending stress due

to this measure.

Instruments with enamel coating should be treated very carefully and

shocks should be avoided. Unpack SITRANS LVL200E directly before

installation. Insert SITRANS LVL200E carefully into the vessel open-

ing and avoid touching any sharp vessel parts.

The second seal of the gas-tight leadthrough (option) prevents an

uncontrolled leakage of the medium. The service life of the gas-tight

leadthrough depends on the chemical resistance of the materials.

See "Technical data".

Caution:

If it is determined (e.g. via an error message from SITRANS LVL200E)

that medium has already penetrated into the vibrating element, the

instrument must be exchanged immediately.
