constitute a potential risk of ignition by impact or friction. Care
must be taken into account during installation and use to prevent
impact or friction. ( When installed in a Ga Approval)
2. The maximum permitted ambient temperature of the Level Plus
Digital/Analog Level Transmitter is 71 °C. To avoid the effects of
process temperature and other thermal effects care shall be taken
to ensure the surrounding ambient and the ambient inside the
transmitter housing does not exceed 71°C
