There needs to be a procedure alignment
The sensor is a kind of detection device, which can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control.
Characteristics of sensors include miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the first stage to realize automatic detection and control. With the existence and development of sensors, objects have senses of touch. Taste and smell, and gradually become alive. Generally, according to its basic perception function, it can be subdivided into ten categories: thermal sensor, light sensor, gas sensor, force sensor, magnetic sensor, moisture sensor, sound sensor, radiation sensor, color sensor and taste sensor.

The measured value of the wind speed sensor always shows 30M/s.
Countless friends often encounter a problem when using the wind speed sensor. The measured value of the sensor is only shown in a fixed number in the terminal system, such as 30M/s, then the measured value of the wind speed sensor always shows 30M/s. what does it mean?
The current wind speed is 30 meters per second. There may be measurement errors or the sensor is divided.
What is the meaning of writing 0.2m/s on the wind speed sensor?
The speed of the air (the speed of the wind) is how many meters per second.
Start at 0.2 m/s, possibly below this wind speed, the sensor will not work.
Is there a sensor that senses the direction and size of the wind?
Find out how much wind you are measuring. If the wind speed is relatively unimportant, you need to use a hot wind speed direction sensor or an ultrasonic wind speed head direction sensor. If the wind speed is relatively large, you can use a wine cup type sensor to measure with a wind vane.
The above three sensors can simultaneously output the wind speed and the wind direction. The wind direction measured by the ultrasonic and thermal sensors is three-dimensional, and the wind direction measured by the wind vane is two-dimensional.
In addition, if wind direction output is not required, a universal hot wind speed sensor can be used, which has no direction output, but it can be measured regardless of the direction of the wind.
Can the sensor wire of the wind speed alarm be extended?
Can.
The anemometer consists of a microprocessor and a highly dynamic wind sensor that can observe instantaneous wind speed in the atmosphere and the average wind speed in two minutes and ten minutes. It has wind speed alarm setting and alarm output control function; wind speed alarm The instrument adopts dual-screen display output, the wind speed display adopts high-brightness LED digital tube display, and the observation distance is long, and it is suitable for dark light and nighttime use. The parameter setting adopts graphic liquid crystal LCD display, and the human-machine interface is friendly; the wind speed alarm device comes with Sound and light alarm, when the wind speed exceeds the limit, the alarm will sound and light alarm to remind the operator to pay attention to safety and generate a relay switch output.
How to transfer the data of the wind direction wind speed sensor to the PLC (Siemens 7200) to control the rotation of the motor to realize the wind rotation of the flagpole
Mainly look at the output of the wind direction sensor. If you can integrate the output into 4-20mA current or 0-10V voltage, you can directly connect to the analog input port of the PLC. According to the response curve, the wind direction and wind speed can be obtained.

A high quality wind speed sensor should have the following characteristics:
Automatic adjustment of the zero function;
Automatic adjustment of sensitivity function;

What is the supply voltage of wind speed and direction sensor ec9-1?

The sensor is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to satisfy the information transmission, processing, storage and display. Requirements for recording, control and control.
The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. It is the first stage in achieving automatic detection and automatic control. The existence and development of the sensor allow the object to have senses such as touch, taste and the smell, and let the object slowly become alive. Generally, it is split into ten categories, such as thermal element, photosensitive element, gas sensor, force sensor, magnetosensitive sensor, humidity sensor, sound sensor, radiation sensor, color sensor and taste sensor, according to its basic sensing function. .
What is the difference between the wind speed sensor and the air volume sensor?
Not the same, but the two are related, the air volume is equivalent to the product of the wind speed and the cross section of the through-flow port, so the air volume sensor should be the converted wind speed sensor.

What is the working principle of the marine wind speed and direction sensor?
Wind direction wind speed sensor, as its name implies, is a tool to measure wind direction wind speed. It converts the flow velocity variable of air into a signal with a certain corresponding output signal, which can be applied to the measurement level of meteorological, military, aviation, seaport, environmental protection, industry, agriculture and forestry departments. The need for wind parameters.
In these fields of application, wind direction and wind speed are very important parameters, and the wind direction anemometer has become a universal measuring tool. The wind direction anemometer contains two sensors, a wind direction sensor and a wind speed sensor. These two sensors can work simultaneously, measuring two parameters of wind direction and wind speed.
The induction component of the wind speed sensor of the wind direction wind speed monitor is a three-cup type wind cup assembly. When the wind speed is higher than 0.4 m/s, the rotation is generated, and the signal conversion circuit is a hall integrated circuit. Under the horizontal wind driven, the wind cup group rotates, and the magnetic rod disk rotates through the main shaft. Dozens of small magnets on the magnetic pole from a plurality of rotating magnetic fields, and the pulse signal is induced by the Hall magnetosensitive element, and the frequency thereof increases with the wind speed. Large and linear increase. Calculation formula: V=0.1F; V: wind speed, unit: m/s; F: pulse frequency, unit: Hz.
The wind sensor of the wind direction wind speed monitor has a single-plate wind vane with an auxiliary target at the opposite end. The angle conversion requires a seven-digit Gray code photoelectric code disk. When the wind vane rotates with the wind, the code wheel rotates through the main shaft. Each rotation of 2.8125, seven sets of illumination and receiving optoelectronic devices located on the upper and lower sides of the code wheel will generate a new set of seven-bit parallel gray code, which will be shaped and inverted. Phase output. The azimuth-angle-Gray code-binary code comparison table is a key basis for wind direction measurement microcontroller programming.
In general, the two sensors of the wind direction wind speed monitor get the characteristics of good dynamic performance, high linear precision, high sensitivity, wide measuring range, good interchangeability and superior wind resistance.
