unaffected by the chemical and physical proper-
ties of the bulk solid.
It also works when subjected to strong external
vibrations or changing products.
Function monitoring
The electronics module of VEGAWAVE S 61
continuously monitors the following criteria:
•
Correct vibrating frequency
•
Line break to the piezo drive
If one of the stated malfunctions is detected or
in case of voltage supply, the electronics takes
on a defined switching status, i.e. the relay
deenergises (safe state).
Functional principle
The tuning fork is piezoelectrically energised
and vibrates at its mechanical resonance
frequency of approx. 150 Hz. When the tuning
fork is submerged in the product, the vibration
amplitude changes. This change is detected by
the integrated electronics module and conver-
ted into a switching command.

Storage and transport

Packaging
Your instrument was protected by packaging
during transport. Its capacity to handle normal
loads during transport is assured by a test
based on ISO 4180.
The packaging consists of cardboard. This
material is environment-friendly and recyclable.
Dispose of the packaging material via specia-
lised recycling companies.

General instructions

Switching point
In general, VEGAWAVE S 61 can be installed
in any position. The instrument only has to
be mounted in such a way that the vibrating
element is at the height of the desired switching
point.

Transport
Do not hold VEGAWAVE S 61 on the vibrating
element. Especially with flange and tube versi-
ons, the sensor can be damaged by the weight
of the instrument.
Remove the protective cover just before moun-
ting.
Handling
The vibrating level switch is a measuring instru-
ment and must be treated accordingly. Bending
the vibrating element will destroy the instrument.
Warning:
The housing must not be used to screw
the instrument in! Applying tightening
force can damage internal parts of the
housing.
Use the hexagon above the thread for
screwing in.

Mounting instructions

Mounting socket
The vibrating element should protrude into the
vessel to avoid buildup.
Filling opening
Mount the instrument in such a way that the
tuning fork does not protrude directly into the
filling stream.
