the measured product and the process temperature.

For this reason, use a screening tube or a longer insulation. The

4.2 Mounting instructions

Duetotheeects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 electrode for VEGACAP 62, but check if you

canmountashortlevelswitchonthesideofthevesselinhorizontal

position.

Extreme vibration caused by the system, e.g. due to agitators or

turbulenceinthevesselfromuidisation,cancausetheprobeof

VEGACAP 62 to vibrate in resonance. If a longer rod version is neces-

sary, you can secure the probe by fastening a suitable isolated brace

or guy directly above the end of the rod.

Iftheinstrumentismountedinthellingstream,unwantedfalse

measurement signals can be generated. For this reason, mount the

instrument at a position in the vessel where no disturbances, e.g. from

llingopenings,agitators,etc.,canoccur.

This applies particularly to instrument versions with a longer probe.
