The brightness sensor HFR/A registers the brightness from 0-20 kLux using a photo-diode and, optionally, also the temperature from 0...+50°C. For further processing the transducer converts the measuring result into a linear output signal 0-10 V respectively 4-20 mA. 3 different measuring ranges be selected (0-0.5 kLux, 0-1 kLux, 0-20 kLux) which can be switched, according to requirements, by the innovative DIP switching technology. The modern room housing in modern design is specially designed for indoor use. The brightness sensor is optimally suited for an energy efficient control of buildings, such as e.g. controlling the lighting in offices, industrial facilities etc..
