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 or core processor, but does not affect temperature ratings.
