Determining a Location
Environmental limits
The maximum ambient temperature for the sensor depends on the electronics option:
• For F-Series sensors with a junction box or an extended core processor, the maximum ambient
temperature is 140 °F (60 °C).
• For all Model F300A sensors, the maximum ambient temperature is 140 °F (60 °C).
• For F-Series sensors with an integral core processor or Model 1700/2700 transmitter, the maximum
ambient temperature is described by the graph in Figure 8. To determine your maximum ambient
temperature, locate the range within which your maximum process temperature falls on the horizontal
axis of the graph, then find the intersecting maximum ambient temperature on the vertical axis.

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/atex. CSA ambient temperature limits are listed in Table 1.
