    Visibility monitoring instrument [visibility monitoring weather station] [FT-NJD10] Instrumen Pemantauan Visibilitas visibility monitoring station is distributed along the highway by a number of visibility monitoring stations networked, the visibility, wind direction, wind speed, temperature, humidity, atmospheric pressure along the highway automatic monitoring, and the monitoring information is transmitted to the monitoring in time, for the reference of the traffic control system, in the bad weather conditions can be timely issued warning information, Inform managers and drivers in a variety of ways to improve the level
    of driving on the highway.

    Product features 1.
    Visibility meter: It is composed
    of main components such as light emitter, light receiver and microprocessing controller.

    The emitter emits infrared pulse light, the receiver simultaneously detects the pulse light intensity of the forward scattering of aerosol particles in the atmosphere, all the measurement information is collected by the microprocessor controller and converted into meteorological optical visual range (MOR) 2.
    Temperature, humidity, wind speed, wind direction, atmospheric pressure, Piezoelectric rain six-element integrated sensor 3.
    Wind speed and wind direction sensor: probe the head cover to hide, to avoid the interference of rain and snow, to avoid natural wind obstruction
    .

    The principle is to transmit continuous frequency conversion ultrasonic signals, and detect wind speed and wind direction 4.
    Piezoelectric rainfall by measuring the relative phase: The piezoelectric rainfall sensor uses PVDF piezoelectric film as a rain-sensing device, and distinguishes the raindrop signal through the embedded AI neural network to avoid false triggering
    due to sand, dust, vibration and other interference.
