2.1 General
Due to the influence of the process temperature, ultrasonic flow sensors in separate version
with type designation OPTISONIC 6000 xxxxxx-Ex are not allocated to any fixed temperature
class. For the temperature classification table refer to
OPTISONIC 6000 xxxxxx-Ex on page 12.
The temperature limits apply under the following conditions:
• The instrument is installed and operated in accordance with the installation directions given
in the quickstart and handbook.
• The instrument is not heated up by any additional heat radiation (direct solar radiation, heat
from adjacent plant parts) so causing it to operate above the permissible ambient
temperature range.
• Insulation is not hindering free ventilation of the ultrasonic signal converter housing.
