Brightness Transmitter

The instrument serves for the acquisition of the daylight intensity, and is adapted to the sensitivity of the human eye. The linearized electrical output signal can be used for the control of shading devices, heating systems, and irrigation plants.

Brightness Transmitter
Direction-independent

Measuring sensor for the acquisition of the brightness. It can be used for the regulation of shading devices, heating and irrigation plants in automatically controlled green houses or as twilight sensor.
There are two analogue outputs available: output 1 offers different, selectable measuring ranges. Output 2 is used as fixed measuring range, particularly for the twilight range. The output signals can be delivered as voltage or current.

Brightness Transmitter
Direction-independent „with heating“

Measuring instrument for the acquisition of the daylight intensity.
The electrical output can be used for the regulation of shading devices, heating and irrigation plants.
The acquisition is carried out in the upper part (dome) of the instrument. The acquisition angle is ± 90 degrees.
The model with “heating” avoids a possible dewing on the dome.

Brightness Transmitter
Sector-dependent

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.
