Temperature limits

All models except high-

temperature models

(1) (2) (3) (4)

(1) Temperature limits may be further restricted by hazardous area approvals. See pages 21–27.

(2) The temperature graphs shown here are for use only as a general guide.

(3) 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.

(4) The temperature limits shown apply only when the electronics are not covered (for example, by insulation). If the sensor case must be

insulated, use extended mount electronics.
