• IMPORTANT NOTE!
• Ambient temperature considerations
• The C520/C520X temperature transmitter has been developed for an ambient
temperature range from -40 to 85°C (-40 to +185°F). Please also note that the ambient
temperature is also dependent on the temperature category in Section 6.1.5 and 6.2.5, Ex
data of the ambient temperature.
The process temperature is also transferred to the transmitter housing via the protective tube.
If the process temperature is close to or exceeds the maximum specified process temperature,
then the temperature in the transmitter housing can rise above the maximum permissible
ambient temperature. Always check that the ambient temperature where the transmitter is
installed is always within the permissible range. One way to decrease heat transfer via the
protective tube is to make the protective tube longer or in general to install the transmitter
farther away from the heat source. The same safety measures can be taken if the temperature
is below the specified minimum temperature.
