The light intensity sensor/twilight sensor PHOTASGARD AHKF, with six switchable measuring ranges (six devices in one) measures the luminous intensity and is used to control luminaries, lighting systems, Venetian blinds and canvas blinds, etc., to monitor lighting conditions at workplaces, in greenhouses, storage halls, workshops, corridors, in outdoor areas, in industrial halls, in offices as well as in residential and business facilities, for daylight-dependant constant light control, as light intensity or twilight sensor and to control sunshade equipment avoiding unnecessary heating-up of rooms. It therefore minimizes your variety of types and stock keeping while covering a greater range of universal applications.

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. Therefore, with its special filter, the sensor is ideally suited to exposure measurement of daylight and/or for measuring artificial light of high colour temperature (similar to sunlight).

The room light intensity sensor PHOTASGARD RHKF with four switchable measuring ranges (four devices in one), measures the light intensity by means of a diffusor and is used to control luminaires, lighting systems, Venetian blinds and canvas blinds, to monitor lighting conditions at workplaces, in storage halls, workshops, corridors, in indoor areas, in industrial halls, in offices, as well as in residential and business facilities, for daylight-dependent constant light control, as light intensity or twilight sensor and to control sunshade equipment avoiding unnecessary heating-up of rooms.

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.

The ceiling-installed sensor KINASGARD / PHOTASGARD DBWF/LF/FTF is used to detect persons at a distance of up to 10 meters, luminous intensity or brightness, relative humidity and temperature. It is used for installation in suspended ceilings.

The sensor detects motion over an aperture angle of 110° and a perimeter of 360°. The pantented lens system with 20 individual lenses results in only very small dark areas that are only a few centimeters wide even at a distance of 10m, thereby reliably detecting small movements. If motion is detected, the potential-free relay output is switched. The hold time of the output, measured from the moment of the last detected movement, can be preset internally in the device via potentiometer within a range of 4 seconds to approx. 17 minutes.

For the temperature and humidity, an analogue output of 0-10 V corresponding to 0...+50°C and 0...100 % r.H. is available. Deviations due to the mounting position and location can be compensated internally using one offset regulator respectively.

For the Luminous intensity and brightness of 0...1000 lux or 0...5000 lux (selectable via DIP switches), an analogue output 0-10 V is also available. It is also possible to activate the motion output depending on brightness with the help of DIP switches.

Fields of application for the DBWF/LF/FTF include residential room monitoring, automatic switching of lights, control technology, alarm technology, and motion-dependent control of room functions, e.g. for lowering the temperature in unused rooms.
