3.2 Principle of operation
VEGADIS 12 is an adjustment and indicating unit for the following VEGA pressure transmitters:
•VEGAWELL 72 4 … 20 mA/HART
•VEGABAR 74 4 … 20 mA/HART
•VEGABAR 75 4 … 20 mA/HART
VEGADIS 12 has the following functions:
•atmospheric pressure compensation for the pressure transmitter
•Adjustment of the pressure transmitter
•Indication of the measured value (optional)
VEGADIS 12 is looped in the supply and signal circuit of the pressure transmitter and requires no separate external energy. Connection is carried out via screw terminals in the housing.
3.3 Operation
As a standard feature, VEGADIS 12 is equipped with an adjustment module for the pressure transmitter. The optional indication is located in the housing cover and is equipped with a bargraf and a digital indication. In this version, the additional 20591-EN
