Outdoor Light Detector LGT 010
For omnidirectional recording of the lighting intensity and its
transmission as a standard signal to, for instance, shading and heating
systems in automated greenhouses, or to building management systems for
shading and light control, and for further processing in the DDC.
The "twilight" output provides a more accurate detection of the
beginning and the end of the daylight period, allowing a more systematic
application of energy-saving measures, (e.g. increasing or decreasing
set values, thermal screen operation, etc.), as well as the
implementation of growth-control measures, such as the "cool-morning"
strategy in plant cultivation.
The omnidirectional light detector converts the light intensity of two
light measuring ranges into standard signals.
Two separate voltage outputs 0 ... 10Vdc are assigned to the ranges 0
... 100 kLux (daylight) and 0 ... 10 kLux (dusk).
The light detector is constructed in such a way that irrespective of the
sun's angle of incidence the actual light intensity is measured.
The light sensor is supplied with mast mounting accessories.
