5. Technical Data
5.1 Electrical Parameter
Before connecting the voltage supply, ensure that all gas lines to the measuring element and the measuring
element itself have been flushed.
Supply voltage: +24 VDC ± 10 %
Power consumption: < 2.0 W
5.2 Gas pressure parameter
Inlet pressure: min. 960 mbar absolute, max. 1.100 mbar absolute
Permissible overload: 1.150 mbar absolute
Outlet pressure: Equal to inlet pressure minus pressure drop of around 10 mbar
5.3 Operating temperature
Adhere to the permissible ambient and medium temperatures which are valid for this area on the basis of the
specified temperature classes. The maximum permissible temperature range is specified on the type plate of
the BlueEye™ Ex-D. Operation of the device is only permitted within these specified ranges.
Ambient air temperature range: -20°C to 70°C
Operating gas temperature range: 0 to 50°C
Maximum surface temperature: 80°C
Protect the instrument from influences by external heat sources (e.g. pipes or tanks).
5.4 Measured media
Dry, neutral gas (filtered 10 µm)
The BlueEye™ Ex-D can measure gas compositions in a wide range, in the form of H-gas or L-gas, as well as
biogas or other (natural and synthetic) gas compositions. However, to ensure accuracy and warranty
period, the gas composition range should be within the following range:
