KROHNE OPTISOUND 3050C 4wire EN - Manual (Page 8)

3.2 Principle of operation
OPTISOUND 3050 C is an ultrasonic sensor for continuous
level measurement. It is particularly suitable for solids, but is
also good for liquids.
The transducer of the ultrasonic sensor emits short ultrasonic
pulses in the direction of the measured product. These pulses
are reflected by the product surface and received by the
transducer as echoes. The running time of the ultrasonic
pulses from emission to reception is proportional to the
distance and hence to 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 power supply range can differ depending on the instru-
ment version. The exact range is stated in the "Technical data"
in the "Supplement".
Measured value transmission is carried out via the 4 ... 20 mA/
HART output, which is separated from the power supply.
3.3 Adjustment
OPTISOUND 3050 C can be adjusted with two different
adjustment media:
l
the indicating/adjustment module
l
a HART handheld
The entered parameters are generally saved in OPTISOUND
3050 C, optionally also in the indicating/adjustment module.
3.4 Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc. to DIN EN 24180.
The packaging of standard instruments consists of environ-
ment-friendly, recyclable cardboard. For special versions, PE
foam or PE foil is also used. Dispose of the packaging material
via specialised recycling companies.
