Notes:
1. When ambient temperature is below –40 °F (–40 °C), a core processor or Model 2400S 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.
2. Temperature limits may be further restricted by hazardous area approvals.
3. The extended mount option allows the sensor case to be insulated without covering the transmitter, core processor, or
junction box, but does not affect temperature ratings.
4. 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.
