2.4 Configuration of measuring sys-
tems
A measuring system consists of a sensor
with a 4 … 20 mA signal output and a module
that evaluates and further processes the
level-proportional current signal.
On the following pages you will find instru-
ment configurations designated as measur-
ing systems, several of which are shown with
signal conditioning units.
2.3 Approvals
When using ultrasonic sensors in Ex areas or
in marine applications, the instruments must
be suitable and approved for the explosion
zones and application areas.
The suitability is tested by approval authori-
ties and is certified in approval documents.
VEGASON 50 ultrasonic sensors are ap-
proved for Ex zone 1, 10, 11, 21 and 22.
Please note the attached approval docu-
ments when using a sensor in Ex area.
