VEGASON 51K … 53K
CE-conformity
VEGASON series 50 ultrasonic sensors meet the protective regulations of EMVG
(89/336/EWG) and NSR (73/23/EWG). The conformity has been judged acc. to the following
standards:
EMVG Emission
EN 50 081 - 2: 1993
Susceptibility
EN 50 082 - 2: 1995
NSR
EN 61 010 - 1: 1993
Outputs and processings
Display indication
Indication
- optional integrated in the sensor, scalable
analogue and digital meas. value indication
- optional external meas. value indication,
powered by the sensor and up to 25 m away
from the sensor (also the adjustment module
MINICOM can be inserted)
Signal output
Signal output
- two-wire technology
4 … 20 mA (load dependent on supply
voltage, see load diagram page 17)
- four-wire technology
4 … 20 mA (load max. 500
W
)
Resolution of the 20 mA-signal
0,025 % of operating range
Failure of the 20 mA-signal
< 0,025 % of operating range
Two-wire technology:
The analogue 4 … 20 mA-output signal (measuring signal) is transmitted together with the
power supply via a two-wire line.
Four-wire technology:
Separate power supply.
The analogue 4 … 20 mA-output signal (measuring signal) is looped by a line separated
from the supply voltage.
