" 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
Display scalable, analogue and digital display of
measured values (option).
An external measured value display, powered by the sensor, can be mounted at a distance
of up to 25 m from the sensor.
Signal output
Signal output
- two-wire technology
4 … 20 mA (see diagram)
Resolution of the 20 mA signal 0.025 % of range
Load 0 … 500
Ω
Two-wire technology:
The analogue 4 … 20 mA output signal (measuring signal) is transmitted together with the
power supply via one two-wire cable.
