VEGA VEGASWING S 51 - Manual (Page 15)

If a malfunction is detected or in case of power
failure, the electronics takes on a defined switching
condition, i.e. the output is open (safe condition).
Functional principle
The tuning fork is piezoelectrically energised and
vibrates at its mechanical resonance frequency of
approx. 1200 Hz. The piezos are fixed mechan-
ically and are hence not subject to temperature
shock limitations. The frequency changes when the
tuning fork is covered by the medium. This change
is detected by the integrated electronics module
and converted 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
according to DIN EN 24180.
The packaging consists of cardboard. This material
is environment-friendly and recyclable. Dispose of
the packaging material via specialised recycling
companies.
