2.2.3 Process temperature
The relation between temperature class, maximum process temperature and maximum
ambient temperature are given in the tables that follow. The minimum permitted ambient
temperature is also given for low process temperatures.
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.).
•
Do not put insulation on the limit switch. Make sure that the airflow around the device is
sufficient. It is permitted to have insulation around the measuring chamber.
•
Make sure that the ambient temperature is within the limits given in the temperature tables.
WARNING!
Make sure that the process temperature and ambient temperature are not more than the values
given in the tables.
WARNING!
If the bypass level indicator has insulation that was supplied by the manufacturer of the device,
refer to the "with insulation" column of the tables that follow.
If you installed insulation on the bypass level indicator, do not refer to the temperature tables in
these supplementary instructions. Make sure that the service temperature of the limit switch is
not more than the maximum values. For more data, refer to Ambient and service temperatures
on page 8
