Temperature Effects
The transmitter will operate within specifications for ambient temperatures between -40 and
185 °F (-40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter
housing. If the expected process temperature is near or beyond specification limits, consider the use
of additional thermowell lagging, and extension nipple, or a remote mounting configuration to iso-
late the transmitter from the process.
