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.

Long-term storage of electronics at ambient temperatures below –40 °F (–40 °C) is not

•
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

The extended-electronics option allows the sensor case to be insulated without covering the
transmitter or core processor, but does not affect temperature ratings.
