VEGA VEGASCAN 850 - Manual (Page 8)

8 VEGASCAN 850
2 Types and versions
2.1 Type overview, VEGASCAN 850
Either 15 or 30 series 50 ultrasonic sensors
can be connected to VEGASCAN 850. The
measured data are outputted in the ordered
field bus protocol by the ordered interface.
The field bus protocol and interface type are
determined by the ordered version of VEGA-
SCAN. The type label of VEGASCAN contains
the bus protocol and the interface type (see
chapter "2.3 Type code of VEGASCAN 850“).
Optional field bus protocols:
- Siemens 3964
- Modbus
- VEGA-ASCII
- Profibus DP
- Profibus FMS
Optional interface types:
- RS 232
- RS 422
- RS 485
- TTY

2.2 Type overview, sensors
VEGASON series 51 … 56 sensors are a
newly developed generation of extremely
compact ultrasonic sensors for large measur-
ing ranges (VEGASON 54 ... 56) or for
shorter measuring ranges (VEGASON
51 … 53).
Due to the small housing dimensions and
process fittings, the compact sensors do
your level monitoring inconspicuously, and
above all, at reasonable cost.
Because of price, reliability and easy han-
dling, ultrasonic level measurement can be
now used in applications in which non-con-
tact level measurement could never be used
before.
VEGASON 50 ultrasonic sensors utilise two-
wire technology perfectly. The supply voltage
and the digital output signals of 15 sensors
are transmitted between VEGASCAN 850
and the sensors via one two-wire cable.
Swivelling holders allow quick alignment of
the transducer to the product and solid sur-
face. Mounting is simplified by the option of
separating the sensor electronics from the
transducer. The sensor electronics can be
mounted at a distance of 300 m from the
transducer. It is then possible to mount the
transducer in environments with an ambient
temperature up to 150°C (type 56).
