Illuminance or incident lighting determines the amount of light that covers a specific surface or area within a tunnel. The ILLIOS measures the level of illuminance within the tunnel bore to help ensure interior illumination levels are continuously maintained in order to provide safe lighting condition for drivers.
The ILLIOS has a stainless steel, IP67 rated case that has been designed specifically for harsh tunnel environments. The ILLIOS measures the illuminance over a standard range of 0-20,000 Lux, which can be scaled to meet the user’s environment. The ILLIOS is a self-contained intelligent analyser, measurements are available via RS485 (Modbus RTU), Current Outputs and Digital Relays.
