  • 461201 | Sensor for brightness


    The sensor signal does not depend on any direction of the incident light and is adjusted to the sensitivity of the human eye. It is designed to measure the brightness of the daylight in the upper half sphere.
    Both outputs of the sensor have a brightness proportional voltage or current signal. The signals can be used as input for controls of shading systems, heating plants or irrigation plants or in automated greenhouses or as twilight switch.
    measuring range 0 to 10 / 50 / 100 / 150 kLux
    accuracy ± 3 % F.S.
    signal 1
    0 to 20 mA or 4 to 20 mA
    (maximum load 350 Ohm with current signal)
    or 0 to 10 V (max 5 mA)
    signal 2 same as signal 1, but for 0 to 1 kLux
    spectral range 350 to 820 nm
    visible azimuth 180°
    powersupply 15 to 36 V DC or 15 to 24 V AC
    fit for use -30 to +70 °C
