Figure 6 High-temperature and extreme high-temperature ELITE sensor ambient and
process temperature limits
Hazardous area approvals may impose additional limits on ambient and process temperature. For the ATEX
“T” rating, refer to the ATEX documentation shipped with the sensor or available on the Micro Motion web
site at www.micromotion.com. IECEx and NEPSI approvals also use the ATEX “T” rating. UL and CSA
ambient temperature limits are listed in Table 1.

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.
