Notes
• When ambient temperature is below –40 °F(–40 °C), a core processor or transmitter must be
heated to bring its local ambient temperature to between –40 °F(–40 °C) and +140 °F(+60 °C).
Long-term storage of electronics at ambient temperatures below –40 °F(–40 °C) is not
recommended.
• Temperature limits may be further restricted by hazardous area approvals. Refer to the hazardous
area approvals documentation shipped with the sensor or available from the Micro Motion web site
(
www.micromotion.com ).
• The extended-electronics option allows the sensor case to be insulated without covering the
transmitter, core processor, or junction box, but does not affect temperature ratings.
• For the purposes of selecting electronics options, this graph should be used only as a general guide.
If your process conditions are close to the gray areas, it may be inappropriate to use electronics
options other than a junction box. Consult with your Micro Motion representative.
1.4 Recommendations for hygienic and self-
draining applications
For optimal cleanability and drainability:
• If possible, install the sensor in a vertical pipeline with the process fluid flowing
upward through the sensor.
