VEGA EL 8 Conductive probe - Manual (Page 9)

4 Mounting
4 .1 General instructions
In general the level switch can be mounted in any position. The
instrument must be mounted in such a way that the probe is at the
height of the requested switching point.
The probe is provided with a special hexagon for tightening. Due to the
hexagon shape, the housing itself can be used to screw the instrument
in.
The wrench size is stated in chapter "Supplement" under "Dimen-
sions".
Use the recommended cables (see chapter "Connecting to power
supply") and keep the opening for the cable as small as possible.
You can give your EL 8 additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.
Do not hold EL 8 on its electrode rods. Particularly with long rod
versions, the sensor can be damaged by the weight of the instrument.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
4 .2 Mounting instructions
Due to agitators, equipment vibration or similar, the level switch can be
subjected to strong lateral forces.
