Guide to Choosing the Right Visibility Detector by Fengtu Technology

In fields such as meteorological monitoring and traffic control, accurate measurement of visibility is required. Fengtu Technology, a manufacturer of meteorological stations, has launched a variety of Visibility detectors, including portable models, professional models, coastal models, and explosion-proof models, to meet different scenarios and needs. However, faced with such a rich variety of products, how should consumers make a choice? Next, the editor of Fengtu will take you on an in-depth understanding to help you select the most suitable one.

I. Portable Visibility detector

The main recommended models are FT-BN10 and FT-BN20.

These two models have the same configuration functions, with the difference lying in their measurement ranges. The measurement range of FT-BN10 is within 10 km, and that of FT-BN20 is within 20 km.

The product measures visibility using the forward scattering method. It adopts an integrated portable design, which is lightweight and easy to carry. It can be used immediately after powering on. It is equipped with a 10.1-inch high-brightness touch screen to display data and historical curves in real time. It has a built-in large-capacity SD card (8G) to save data in real time, and supports query and export.

FT-SN10 is a handheld Visibility detector specially designed for outdoor quick inspection. It uses a unique method to suck air into a closed sampling chamber, and the measurement is not affected by external interference. The measurement range is from 20 m to 10 km, and the aluminum alloy handle is convenient to hold. The battery life exceeds 72 hours. Through the touch display screen, Bluetooth, and APP, data acquisition and transmission are convenient, making it suitable for on-site inspections.

II. Visibility detector for drones

The model is FT-WJN4.

It is specially designed for unmanned aerial vehicles and small unmanned inspection aircraft. It is small in size, only 94mm×69mm×42mm, and weighs 110 grams. It can be easily mounted on the drone platform. The detection range is from 10 m to 4000 m, the measurement accuracy is ±15%, and the power consumption is low, only 0.9W, effectively extending the battery life.

III. Traffic (cast aluminum) Visibility detector

The measurement range can be extended to 20Km, 30Km, 50Km, 80Km, 100 Km.

The representative models are FT-N10, FT-N30, FT-N50, FT-N80, etc.

This series of products is specially designed for the traffic field, so it uses a cast aluminum body. This is because the instrument is installed along the highway and may face the erosion of rainwater, moisture, salt spray, etc. The cast aluminum material has good corrosion resistance and can resist the influence of these natural factors, and is not easy to rust and damage, which can maintain the stable performance of the instrument for a long time. Moreover, compared with some other metal materials, cast aluminum is relatively lightweight, which is convenient for the installation, disassembly, and maintenance of the instrument, and is conducive to the rapid deployment and adjustment of the instrument on traffic facilities, reducing the load-bearing burden of the installation position.

At the same time, because of its small and delicate appearance, it is easy to carry, so it can be stably installed on high-speed vehicles to meet the needs of mobile monitoring.

In view of the importance of weather condition monitoring in the traffic field, we fully consider the needs of customers and provide flexible customization services.

The product can be equipped with a weather phenomenon detection module as needed, which can accurately identify various types of precipitation and snowfall, and can also carefully distinguish different precipitation intensities such as drizzle, light rain, moderate rain, and heavy rain. In addition, it can also be configured with a rainfall detection module to accurately measure the intensity and cumulative amount of precipitation, providing comprehensive and accurate weather data for traffic management departments.

IV. (Coastal) Stainless steel Visibility detector

The representative products are FT-N10A2 and FT-N10A3, both of which use a stainless steel body. The measurement range is from 10m to 10Km (it can be extended to 20Km, 30Km, 50Km, 80Km, 100 Km).

In high-salinity and humid environments such as ships, drilling platforms, and coastal areas, there is a large amount of salt and water vapor, which is highly corrosive to metal materials. Stainless steel contains alloy elements such as chromium and nickel, which can form a dense oxide film on the surface. This oxide film can prevent the internal metal from coming into contact with external substances such as salt and water, effectively preventing corrosion. Therefore, the Visibility detector with a stainless steel body can work stably for a long time in such an environment.

Among them, FT-10A3 is an explosion-proof Visibility detector that can be used in high-risk flammable gas environments.

The above are the currently available Visibility detectors of Fengtu. Due to the limited length of the article, some products have not been mentioned, such as the tunnel Visibility detector.
