5.4 Connection HART standard

The following illustration shows in a simplified way the use of

VEGADIS 82 in conjunction with a HART sensor.

Note:

If the instrument is powered via a VEGAMET signal conditioning

instrument, the communication resistance is already included in the

signal conditioning instrument. The communication resistance in

VEGADIS 82 may not be activated.
