1.3 Temperature limits
Sensors can be used in the process and ambient temperature ranges shown in the
temperature limit graphs. For the purposes of selecting electronics options, temperature
limit graphs should be used only as a general guide. If your process conditions are close to
the gray area, consult with your Micro Motion representative.
The environmental limits of the sensor are as follows:
• Process fluid: –40 to +257 °F (–40 to +125 °C)
• Ambient temperature: –40 to +140 °F (–40 to +60 °C)
Notes
• In all cases, the electronics cannot be operated where the ambient temperature is below –40
°F (–40 °C) or above +140 °F (+60 °C). If a sensor is to be used where the ambient temperature
is outside of the range permissible for the electronics, the electronics must be remotely
located where the ambient temperature is within the permissible range, as indicated by the
shaded area of the temperature limit graphs.
• Temperature limits may be further restricted by hazardous area approvals. Refer to the
hazardous area approvals documentation shipped with the sensor or available from the Micro
Motion web site (www.micromotion.com).
• The extended-mount electronics option allows the sensor case to be insulated without
covering the , but does not affect temperature ratings. When insulating the sensor case at
elevated process temperatures (above 140 °F), please ensure electronics are not enclosed in
insulation as this may lead to electronics failure.
