Thies GmbH – Brightness Transmitter Sector-dependent – Byggautomasjon Lysstyrke sektorisert 0-10VDC

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 )

Mode of operation:
The infalling light is transformed by sensors (photo diodes) and the connected electronics into proportional output values, which act linearly to the brightness. Every electrical output corresponds to a sector of 454 ° (7.1414.60.000) resp. 90 ° (7.1414.61.000). The sectors are centrally related to the directions.
Due to the special construction the sensors are aligned to a average elevation angle (height).
The brightness transmitters are equipped with heating in order to avoid a possible dewing.
