Room light intensity sensor PHOTASGARD® RHKF
The PHOTASGARD® RHKF room light intensity transmitter with four switchable measuring ranges (four devices in one), measures the light intensity by means of a diffusor and serves to control luminaires, lighting systems, Venetian and canvas blinds, and to monitor lighting conditions at workplaces, in storage halls, workshops, corridors, indoor areas, industrial halls, offices, residential and business facilities. It can also be used as a light intensity or twilight sensor device for daylight-dependent constant light control, or for control of sunshade equipment to avoid undesired heat-up of rooms.
As a multi-functional device, this light intensity measuring transducer minimises your variety of types and stock keeping while covering a greater range of universal applications. The sensor has been specifically adapted to the sensitivity of the human eye. Its greatest sensitivity is in the range of 350 nm to 820 nm. Therefore, with its special filter,it is ideally suitable for exposure measuring of daylight and/or for measuring artificial light of high colour temperature (similar to sunlight).
