“ NPT with ExD housing
CE conformity
VEGAFLEX sensors meet the protective regulations of EMC (89/336/EWG) and NSR
(73/23/EWG). Conformity has been judged acc. to the following standards:
EMC
Emission EN 50 081 - 1: 1992
Susceptibility EN 50 082 - 2: 1995
NSR EN 61 010 - 1: 1993
Display
Indication scalable analogue and digital measured value
display (option).
An external measured value display powered by the sensor can be mounted up to 25 m
away from the sensor.
Signal output
Signal output digital output signal in two-wire technology
(Profibus)
Two-wire technology:
The digital Profibus output signal (measuring signal) is modulated onto the power supply
and is further processed in the signal conditioning instrument or in the processing system.
