As the name suggests, the wind direction and speed sensor is a tool to measuring wind direction and speed. It is a machine that converts the variable of air flow velocity into a corresponding output signal, and can be widely used in meteorological, military, aviation, harbor, environmental protection, industry, agriculture and forestry departments to measure horizontal wind parameters.
In these applications, wind direction and speed are of great importance parameters, so
the wind direction anemometer has become a universal measuring tool. Wind direction anemometer contains two sensors, wind direction sensor and the wind speed sensor. The two sensors work simultaneously to measure both wind direction and speed.
The sensor component of the wind speed sensor of the wind direction and wind speed monitor is a three-cup wind cup component, which generates rotation when the wind speed is greater than 0.4m/s, and the signal conversion circuit is all integrated circuit. The horizontal wind drives the downwind cup configure on rotate, and the magnetic rod is driven to rotate by the spindle. dozen of small magnets on it from a number of rotating magnetic fields, and the hall magnetic sensor induces pulse signals, whose frequency increases linearly with the increase of wind speed. Calculation formula:V= 0.1f; V: wind speed, unit:m/s; F: pulse frequency, unit:Hz.
The sensing component of the wind direction sensor of the wind direction and speed monitor is a single-plate van equipped with an auxiliary plate at the front end. Angle conversion using a seven – bit gray code photoelectric code. When the vane rotating with the wind, by rotating the spindle drive code, each roll 2.8125 °, is located in the encoder and seven groups on either side of the light emitting and receiving photoelectric device can produce a new set of seven parallel gray code, after plastic, the inverter output. Azimuth – angle – gray code – binary code comparison table is an important basis for wind direction measurement microcontroller programming.
In general, the two sensors of the wind direction and speed monitor have the characteristics of good dynamic performance, high linear precision, high sensitivity, wide measurement range, good interchangeability, high wind strength and so on.
Below we briefly introduce the downwind wind speed monitor some of the highest performance and technical parameters.
The vane anemometer is offered in three modes: manual, automatic and computer lock. Users can set the three modes according to their need. Convincing data saving function, can store up to 60,000 pieces of data. The anemometer holds the function of 32 channels simultaneous detection, which can realize multi-point synchronous detection.
