PHOTASGARD® RHKF-U

The room brightness sensor PHOTASGARD® RHKF with four switchable measuring ranges (four devices in one), measures illuminance via a diffuser and is used to control luminaires, lighting systems, blinds and awnings. The measuring transducer is used to monitor lighting conditions at workplaces, in warehouses, workplaces, corridors, indoors, in industrial halls, in offices and in residential and commercial premises.

It is also used for daylight-dependent constant light control, as a brightness or twilight sensor and as a sunshade control to prevent unnecessary room heating. As a multifunctional device, it minimizes your variety of types and storage requirements with an extended, universal range of applications. The sensor used is specially adapted to eye sensitivity. The highest sensitivity is in the range from 350 nm to 820 nm. With its special filter, the sensor is predestined for measuring the illuminance of daylight and/or artificial light with a high color temperature (similar to sunlight).
