Overvoltage protection
If the measuring device is used for the level measurement in flammable liquids which requires the
use of an overvoltage protection according to DIN EN 60079-14, standard for testprocedures DIN
IEC 60060-1 (10 kA, Puls 8/20 µs) it has to be ensured that
• the measuring device with integrated overvoltage protection with gas discharge tubes within the
T12-enclosure is used, refer to product overview on → ä 8
or
• this protection is achieved by the use of other appropriate measures (external protection devices
e.g. HAW262Z).
