The brightness transmitter serves for the acquisition of the daylight intensity, depending on the position of the sun. The physical measuring values are output as illumination-proportional voltage and, for example, used for the sun-position-dependent control of shading devices, heating- and irrigation plants.
- The measuring value “brightness” of model 7.1414.60.000 is acquired by eight independent sensors (photo diodes), which are arranged in 45°-segments. (North, NE, East, SE, South, SW, West, NW ).
- The measuring value “brightness” of model 7.1414.61.000 is acquired by three independent sensors (photo diodes), which are arranged in 90°-segments (East, South, West )
