order specification.
3.2 Principle of operation
VEGADIS 82 is suitable for measured value indication and adjustment
of sensors with HART protocol. The instrument is looped directly into
the 4 … 20 mA HART signal line at any location. Separate external
energy is not necessary. VEGADIS 82 also operates exclusively as an
indicating instrument in a 4 … 20 mA current loop.
The instrument is particularly designed for:
•
VEGAPULS WL 61
•
VEGAWELL 52
These sensors have no own display/adjustment.
The housing of VEGADIS 82 contains a filter element for ventilation.
The instrument is thus also used for atmospheric pressure compen-
sation for a submersible pressure transmitter.
The VEGADIS 82 can also be used as an external indicating device
for a four-wire sensor or a VEGAMET signal conditioning instrument
with active 4 … 20 mA output.
The sensor adjustment is carried out in the VEGADIS 82 integrated in
the display and adjustment module.
