Lumios MkIII

Luminance Photometer for Tunnels

The LUMIOS MkIII measures the level of luminance, or brightness, at the tunnel entrance / exit to ensure that the visual perception of drivers is maintained.

Lumios MkIII

The LUMIOS-MkIII measures the level of brightness or luminance created by natural light around tunnel portals. When integrated with a managed tunnel lighting system, the measurements provided by the LUMIOS-MkIII will ensure that the visual perception of drivers is maintained during the day and at night. This avoids sudden variations in lighting and potential “black hole effect” when entering and exiting a tunnel. .

The LUMIOS-MkIII has onboard SCADA / PLC interface options, including Current Outputs, Digital Relays and RS485 (Modbus RTU). The viewing angle can be specified between 8° and 40°. Optional wipers and pumped washer systems are also available for more demanding environmental conditions. The LUMIOS-MkIII is available with both AC and DC power supplies.
