Pwd920A2 Roadside Weather Station Surface Visibility Sensor Scattering Forward Scatter Visibility Meter

PWD920A2 Roadside Weather Station Surface Visibility Road Condition Sensor Scattering Forward Scatter Visibility MeterProduct DescriptionPWD920A2 forward scatter visibility meter provides measurements related to meteorological visibility. The sensor is based on the principle of forward scattering principle and is a new generation of meteorological visibility monitoring equipment developed by Transmissive Detectors.Characteristics:* Real-time, online, and continuous monitoring of atmospheric visibility;* The digital output interface of the instrument is equipped with RS-232 or RS-485 as standard. The interface can be set at the factory according to users' requirements.* It can monitor its own DC power supply, internal temperature, ambient light intensity and other signals, and give the working status and alarm. Sensor Parameters Measurement indicators Measuring range 5m-10km Measurement accuracy ≤ 2km, error ± 2%; 2Km-10km, error ±5%; Instrument consistency ≤ ± 4% Data update interval 15 seconds, 60 seconds optional Power indicator Power supply DC 12V Power less than 1W Mechanical indicators Dimensions (length x width x height) 610mm x 230mm x 300mm Weight less than 10kg Installation Mounted on a erected circular column Material Anodized hard aluminum, painted on the outer surface Environmental adaptability Working environment temperature -40 ~ +60 ° C Working relative humidity 0-100% Geographical adaptability continuous work in the wilderness Product DisplayWorking principle:   PWD920A2 forward scatter visibility meter is designed using the internationally recognized forward scatter principle. It has the integration of transmitter and receiver, no baseline requirements, simple installation, low requirement of geographical location, no impact from vibration, and simple maintenance.The emitter of the visibility meter emits a beam of infrared light having a center wavelength of 0.87 μm into the atmosphere through an infrared light emitting diode, and the receiver combines a certain volume of atmospheric forward scattered light onto the receiving surface of the silicon photoelectric sensor and converts it into the electrical signal which is sent to the acquisition of the controller after processing, and the visibility value is obtained after sampling and calculation by the CPU, and then communicated through the RS232 and the computer.  Application CasePWD920A2 forward scatter visibility meter can be widely used in the field of smog monitoring such as traffic safety, meteorological environmental protection, marine investigation and management.  Company IntroductionFAQQ: Are you a factory/manufacturer?A: Yes, we are professional factory/manufacturer of weather station and relative weather sensors.
