7 Safety Instrumented Systems (SIS)
requirements
A two-wire, 4-20 mA signal representing pressure provides the safety-critical output of
the Rosemount 3051 Pressure Transmitter. The Rosemount 3051 safety-certified pressure
transmitter is certified to:
• Low and high demand: Type B element
• Route 2H, Low Demand application: SIL 2 for random integrity at HFT=0, SIL 3 for
random integrity at HFT=1
• Route 2H, High Demand application: SIL 2 and SIL3 for random integrity at HFT=1
• Route 1H where the SFF ≥ 90%: SIL 2 for random integrity at HFT=0, SIL 3 for random
integrity at HFT=1
• SIL 3 for systematic integrity

Identify Rosemount 3051 safety certification

You must identify all Rosemount 3051 transmitters as safety-certified before installing
them into Safety Instrumented Systems (SIS). To identify a safety-certified Rosemount
3051:
Procedure
1. Check NAMUR Software Revision located on the metal device tag:
2. Verify that option code QT is included and TR is not included in the transmitter
7.2 Installation in Safety Instrumented Systems
(SIS) applications
There are no additional instructions for installing the transmitter in SIS applications.
WARNING
Only allow qualified personnel to install the Rosemount 3051 in SIS applications.
Always ensure a proper seal by installing the electronics housing cover(s) so that metal
contacts metal.
See the Specifications section of the
and operational limits.
Design the loop so that terminal voltage does not drop below 10.5 Vdc when the
transmitter output is set to 23 mA.
(6) NAMUR Software Revision: Located on the metal device tag.

NAMUR Software Revision Number: SW
model code.
Devices used in safety applications with ambient temperatures below -40 °F (-40 °C)
require option codes QT and BR5 or BR6.
