Figure 7 F-Series sensor ambient and process temperature limits (high-temperature and
extreme high-temperature models)
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.

Maximum process temperature in °F (°C)
Ambient temperature of core processor or
transmitter in °F (°C)
Notes:
1. When ambient temperature is below –40 °F (–40 °C), a core processor 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.
