2.2 Area of application
The transmitter can be used in a safety-related system according to
IEC 61508 in the modes low demand mode or high demand mode for
the measurement of the following process variables:
•
Point level detection
•
Level measurement in liquids and bulk solids
•
Interface measurement in liquids
Due to the systematic capability SC3 this is possible up to:
•
SIL2 in single-channel architecture
•
SIL3 in multiple channel architecture
The following interface can be used to output the measured value:
•
Current output: 4 … 20 mA
The following interfaces are only permitted for parameter adjustment
and for informative use:
•
HART
®
•
Display and adjustment module PLICSCOM
•
VEGACONNECT
•
Current output II
