HYGRASGARD
The light-intensity sensor PHOTASGARD
The connecting head is pluggable for quick and easy mounting. The measuring transducer is accommodated in a separate housing.
The sensor used was specifically adapted to the sensitivity of the human eye. Its greatest sensitivity is in the range of 350 nm to 820 nm.
With its special filter, the sensor is therefore ideally suited to exposure measurement of daylight and/or for measuring artificial light of
high colour temperature (similar to sunlight).
It is used for daylight-dependent constant light control, to control luminaires, lighting systems, Venetian blinds and canvas blinds,
and to control light intensity and sun protection hoods to avoid unnecessary heating-up of rooms. It is used in green houses, storage halls,
industrial halls, workshops, corridors, residential and commercial buildings.
