Note
This section applies to 4–20 mA only.
6.1 Safety instrumented systems (SIS) certification
The 3144P Temperature Transmitter is a two wire, 4-20 mA smart device. For safety
instrumented systems usage it is assumed that the 4-20 mA output is used as the primary safety
variable. The transmitter can be equipped with or without the display. The 3144P is classified as
a Type B device according to IEC61508, having a hardware fault tolerance of 0.
The 3144P HART
®
Head Mount transmitter is certified to IEC 61508 for single transmitter use in
Safety Instrumented Systems up to SIL 2 and redundant transmitter use in Safety Instrumented
Systems up to SIL 3.
6.2 Rosemount
®
3144P safety certified identification
All 3144P HART transmitters must be identified as safety certified before installing into SIS
systems.
To identify a safety certified Rosemount 3144P, make sure the device satisfies number 1 below
as well as at least one of options 2, 3 or 4.
1. Verify the transmitter was ordered with Output Option code “A”. This signifies that it is
a 4-20mA/HART device.
a. For example: MODEL 3144PDxA……….
2. See a Yellow Tag affixed to the outside of the transmitter, or the option code QT in the
transmitter model string.
