Snow Depth Detector Sensor Measuring Snow Thickness RS485/4-20mA/50KHz

Snow sensor is an intelligent snow depth sensor that uses ultrasonic remote test technology to monitor the amount of snow to achieve automatic continuous monitoring of snow depth; it calculates the snow depth of the time difference between the time difference of 50kHz ultrasonic measurement from transmitting to the return signal.

Snow deep sensor is an intelligent and sensitive snow -reducing monitoring instrument and equipment that can accurately identify and interference. It can be widely used in measuring meteorology, airports, ports, laboratories, industries, agriculture and transportation.

Connection method 

(1) If equipped with the collector produced by our company, directly connect the sensor to the corresponding interface on the collector using the sensor cable.

(2) If the sensor is purchased separately, the line sequence of the sensor supporting line is as follows:

Red wire: Power + (DC12V)

Black wire: Power -

Yellow line: 485+

Blue Line: 485-

Ultrasonic Snow Depth Detector Sensor Instructions for use  :                          

1. After the sensor indicates the wiring in accordance with the wiring method and installation instructions, place it at a detection position of 1.3m (± 0.1m) to open the snow -capacity sensor probe protection cap.

2. If you are equipped with the collector produced by the company, connect the system, open the protective cover of the snow sensor probe, in the "other settings" of the collector → "Snow Setting", set the starting work temperature of the snow volume sensor, and set the default settings. The snow volume working temperature is t0 (default is 5 ° C, which can be set by itself). After setting the snow temperature, select "Snow Quantity Detection", switch the "stop" mode to the "start" mode, click the "confirm" button, and click the "confirm" button. The system will automatically detect the benchmark height of the sensor; (note: If the height of the snow volume sensor is adjusted, the benchmark height is required according to the above operation).

When the real -time temperature T> T0, the collector automatically close the display value of the snow sensor. When the real -time temperature T <T0, the collector shows the test value of the snow volume sensor to obtain the snow volume information.

1.Snow is conducive to the growth and development of crops, or a substance with good thermal insulation effects, which can protect the plants from frostbite in the cold winter. In the spring of next year, the melting of snow can provide good water supply for vegetation.

2.Blizzard brings extremely constant changes to people's lives and travel; 

3.Blizzard's warning signals are divided into four types: blue, yellow, orange and red. When Blizzard weather is coming, local government departments shall formulate the emergency plan for the Blizzard early warning signal to remind people to take various aspects of countermeasures.

Therefore, it is important for Blizzard's monitoring. Niubol snow deep sensor is a kind of instrument used to monitor snow depth in various fields.

Snowfall is an important part of the water cycle, snowfall has a certain impact on the balanced development of the ecological environment, people's life and production.

But snow days also often hear snow freezing crops thing, generally speaking, if the snowfall lasts for a long time, the amount of snow may cause normal growth of crops stems broken, with the continuous development of science and technology, snow monitoring in the current level of technology, automatic observation equipment gradually replaced the manual observation.

Ultrasonic snow depth sensor using ultrasonic ranging, can be automatic and continuous observation of snow depth, snow volume, snow thickness, thus making the observation data more accurate and continuous.

　Snow depth monitoring equipment is also increasingly used in road traffic, and has an increasingly important role in encountering snowstorm disasters. Improve the meteorological department of the snowfall real-time monitoring and early warning capabilities, can be widely used to serve the traffic warning, agricultural snow warning and other aspects.
