3 Product description
VEGASON 63 • 4 … 20 mA/HART - four-wire
28780-EN-130417
With the serial number, you can access the delivery data of the instru-
ment via www.vega.com, "VEGA Tools" and "serial number search".
In addition to the type label outside, you can also find the serial num-
ber on the inside of the instrument.
3.2 Principle of operation
VEGASON 63 is an ultrasonic sensor for continuous level measure-
ment. It is suitable for liquids and solids in practically all industries.
The transducer of the ultrasonic sensor transmits short ultrasonic
pulses to the measured product. These pulses are reflected by
product surface and received back by the transducer as echoes.
The running time of the ultrasonic pulses from emission to reception
is proportional to the distance and hence the level. The determined
level is converted into an appropriate output signal and outputted as
measured value.
Four-wire electronics with separate power supply.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
Measured value transmission is carried out via the 4 … 20 mA/HART
output separate from power supply.
The backlight of the display and adjustment module is powered by
the sensor. The prerequisite for this is a supply voltage at a certain
level. The exact voltage specifications are stated in chapter "Technical
data".
3.3 Operation
The instrument can be adjusted with the following adjustment media:
•
With the display and adjustment module
•
with the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard, e.g. PACTware and
PC
•
with manufacturer-specific adjustment programs AMS™ or PDM
•
With a HART handheld
3.4 Packaging, transport and storage
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 of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
