ZFD fog detector is used to control the foghorns and marine lights, when the visibility is changing because of changing weather circumstances. The world’s smallest volume, farthest detection distance, and lowest cost ocean application fog detector.
The ZFD fog detector is made of stainless steel 316 material and can withstand harsh ocean backscatter technology. It consists of an optical transmitter, receiver, and microprocessor controller. The transmitter emits infrared light pulses, while the receiver simultaneously detects the intensity pulses generated by atmospheric particle scattering. The maximum detection distance can reach 20Km, and all information is collected through measurement microcontrollers and converted into meteorological visibility distance through specialized mathematical model algorithms. At the same time, it can provide 2 independent relay signal outputs and outdoor illumination data, and the instrument also has a built-in heating function.

What is a Fog Detector/Sensor?
Fog detector is an optical instrument that uses backscatter to measure atmospheric extinction coefficient and obtain meteorological visibility data. It is mainly used in the field of ocean platforms to control foghorns and marine lights systems.
How does a Fog Detecotor/Sensor work?
Fog detectors are instruments primarily used to measure visibility in the marine field. Visibility should be an easy concept. … The Fog Detector system—which includes a transmitter, receiver, and processor—determines visibility. The transmitter sends out a cone of light twice per second.
What does Visibility mean weather?
What Is The Monitoring Distance of Visibility Sensor?
In fact, the monitoring distance is not the actual distance, but the ideal value calculated by the model.
It refers to the distance values that can be detected under the same meteorological conditions, especially in mountainous areas where the fog is obvious, and the measured values can not represent the actual visibility of the local area.
What does good Visibility mean?
The distance at which a given standard object can be seen and identified with the unaided eye. the ability to give a relatively large range of unobstructed vision: a windshield with good visibility.
What is the instrument used to measure visibility?
A typical visibility sensor used at synoptic observing stations is shown below. It applies the forward scattering characteristics of light to measure the extinction coefficient of a beam generated by a high intensity xenon strobe transmitter directed at a volume of air close to the sensor.
