PHOTASGARD® AHKF-I

The brightness sensor/twilight sensor PHOTASGARD® AHKF, with six switchable measuring ranges (six devices in one), measures illuminance and is used to control luminaires, lighting systems, blinds and awnings as well as to monitor lighting conditions at workstations, in greenhouses, warehouses, workplaces, corridors, outdoors, in industrial halls and offices, residential and commercial premises, in daylight-dependent constant light control systems, as a brightness or twilight sensor and for sunshade control to prevent unnecessary room heating.

The multifunctional measuring transducer minimizes your variety of types and stock keeping with an enlarged, universal range of applications. The sensor used has been specially adapted to eye sensitivity. Its greatest sensitivity is in the range from 350 nm to 820 nm. With its special filter, the sensor is therefore predestined for use in measuring the illuminance of daylight and/or artificial light with a high color temperature (similar to sunlight).
