Brightness sensor with photo-diode HFA/A
The brightness sensor HFA/A registers the brightness from 0-100 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. 8 different measuring ranges be selected (0-0.5 kLux, 0-1 kLux, 0-2 kLux, 0-5 kLux, 0-10 kLux, 0-20 kLux, 0-50 kLux, 0-100 kLux) which can be switched, according to requirements, by the innovative DIP switching technology. The robust housing is defined especially for outdoor 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..
