Safety Instrumented Systems (SIS) Certification

The safety-critical output of the Rosemount 3051P is provided through a two-wire, 4 - 20 mA signal
representing pressure. The Rosemount 3051P 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

Rosemount 3051P safety certified identification

All Rosemount 3051P Transmitters must be identified as safety certified before installing into SIS
systems.
To identify a safety certified Rosemount 3051P:
1. Check Namur Software Revision located on the metal device tag. "SW _._._".
2. Verify that option code QT is included in the transmitter model code.

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 10.5 Vdc when the
transmitter output is set to 23 mA.
