1.
When stored or operated at a temperature of less than -30 °C, the IP65.
The PTFE protective conduit may only be used outside the potentially explosive area or, to prevent static charging,
must be fitted with a steel protective conduit or steel tube.securely connected to the local potential equalisation
(contact resistance ≤ 1 MΩ). The steel protective conduit or steel tube must be galvanically connected to the sensor housing.
2.
When used in hazardous areas, the ambient temperatures of the series ds822 ATEX must be observed,
view “Ambient temperature range” on page 22.
