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
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.
About this task
To identify a safety certified Rosemount 3051SMV:
Procedure
1. Verify the model string contains Rosemount 3051SMV and QT.
2. Verify software revision is 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.
Environmental and operational limits are available in
The loop should be designed so the terminal voltage does not drop below 12.0 Vdc when
the transmitter output is set to 23 mA. For more information, see the
