3.2Principle of operation
VEGASWING 61 is a point level sensor with tuning fork for level
detection.
It is designed for industrial use in all areas of process technology and
can be used in liquids.
Typical applications are overfill and dry run protection.With a tuning
fork of only 40 mm length,VEGASWING 61 can be also mounted e.g.
in pipelines from DN 32.The small tuning fork allows use in vessels,
tanks and pipes.Thanks to its simple and robust measuring system,
VEGASWING 61 is virtually unaffected by the chemical and physical
properties of the liquid.
It functions even under difficult conditions such as turbulence,air
bubbles,foam generation,buildup,strong external vibration or
changing products.
Fault monitoring
The electronics module of VEGASWING 61 continuously monitors via
frequency evaluation the following criteria:
lStrong corrosion or damage on the tuning fork
lLoss of vibration
lLine break to the piezo drive
If one of these faults is detected,the electronics signals it via a defined
current to the signal conditioning instrument.The connection cable to
the sensor is also monitored for line break and short-circuit.
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx.1200 Hz.The piezos are
fixed mechanically 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,transferred as a current value to the processing system and
converted there into a switching command.
Depending on your requirements,VEGASWING 61 with two-wire
electronics can be connected to different signal conditioning instru-
ments.Compatible signal conditioning instruments are listed in chapter
"Technical data".
The data for power supply are specified in chapter "Technical data".
