(in Germany VDE 0100). The measuring lines must be laid separately from the mains leads. Explosion Prevention! HE 5411 Lite, Basic and Premium with a supply voltage of 19…36 V DC are suitable for use in explosion zones 2 and 22, provided that the lid is closed. -
Page 8: Device Identification
Device Identification Note! The HE 5411 differential pressure transducer is available in three different designs. The corresponding device identification can be seen on the nameplate. Devices with a measuring range of ± 1.25 mbar (regardless of the device version) do not have any ATEX certification! - Page 9 Cleaning is necessary to prevent increased dust generation on the device. Operation under voltage, in zone 22 and 2, only in closed state. Before closing, ensure that the device housing is free of dust. HE 5411 Operating Instructions #340411 | version 1.7...
