Overview
The safety-critical output of the Rosemount 2090 Pressure Transmitter is provided through a two-wire,
4–20 mA signal representing pressure. The Rosemount 2090 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
1.1
Rosemount 2090 safety certified identification
All Rosemount 2090 transmitters must be identified as safety certified before installing into SIS systems.
To identify a safety certified Rosemount 2090:
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.
1.2
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 "Specifications and Reference Data," in the
Reference
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.
