The tables that follow are applicable in these conditions:
•
Device installation must agree with the instructions given in the handbook.
•
Make sure that the device temperature does not increase because of other heat sources
(sunlight, adjacent system components etc.). The device must not be operated above the
maximum permitted ambient temperature.
•
Do not put insulation around the signal converter. Make sure that the airflow around the
signal converter is sufficient. It is permitted to have insulation on the pipe or stilling well and
the process connection.
