6.1
Safety Instrumented Systems (SIS) Certification
The safety-critical output of the Rosemount 3051SMV is provided through a two-wire, 4–20 mA signal
representing pressure. The Rosemount 3051SMV safety certified pressure transmitter is certified to: Low
Demand; Type B.
SIL 2 for random integrity @ HFT=0
SIL 3 for random integrity @ HFT=1
SIL 3 for systematic integrity
The Rosemount 3051SMV must be installed per manufacturer’s instructions, specifications and the
materials must be compatible with process conditions.
The HART
®
Protocol is only used for setup, calibration, and diagnostic purposes and is not for safety
critical operation.
6.2
Rosemount 3051SMV safety certified identification
All Rosemount 3051SMV Transmitters must be identified as safety certified before installing into SIS
systems.
To identify a safety certified Rosemount 3051SMV:
1. Verify the model string contains Rosemount 3051SMV and QT.
–
If the transmitter was ordered as part of a flowmeter, verify the model string reads Rosemount
3051SFx(1–7) and QT.
2. Verify software revision is 3.
6.3
Installation in SIS applications
Installations are to be performed by qualified personnel. No special installation is required in addition to
the standard installation practices outlined in this document. Always ensure a proper seal by installing
the electronics housing cover(s) so that metal contacts metal.
