Notes:
1. When ambient temperature is below –40 °F (–40 °C), a core processor must be heated to bring its local ambient
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.
temperatures below –40 °F (–40 °C) is not recommended.
2. Temperature limits may be further restricted by hazardous area approvals.
3. The temperature extender option allows the sensor case to be insulated without covering the transmitter, core processor,
3. The temperature extender option allows the sensor case to be insulated without covering the transmitter, core processor,
or junction box, but does not affect temperature ratings.
