Maximum Process Temperature Chart
.
Where the chart does not apply, please use your own judgement regarding the use of
SITRANS LR 200. Open the menu View – Peak Values, and click on the temperature tab to see
the maximum and minimum temperatures recorded. These can be used to determine whether
the installation needs to be redesigned.
For example, if the internal temperature exceeds the maximum allowable limit, a sun shield or a
longer nozzle may be required.The peak temperatures indicate the extent of change required to
the installation in order to provide a reliable thermal-operating zone for SITRANS LR 200.
WARNING: Internal temperature must not exceed 80
o
C (176

The chart below is for guidance only. Information to be updated to SITRANS LR
460 information.

• The chart does not represent every
possible process connection
arrangement. For example, it will NOT
apply if you are mounting the LR 200 on
a nozzle greater than 8” nominal, or
directly on a metallic vessel surface.
• The chart does not take into
consideration heating from direct
sunshine exposure.
