Beijing hot bulb anemometer manufacturer_ Price consultation, thermal anemometer is a portable instrument for measuring wind speed, small size, easy to carry. At present, it is widely used to measure the wind speed of pipeline, target environment, meteorology, HVAC, environmental protection, energy-saving monitoring, agriculture and other occasions. At present, the popular thermal anemometer in the market uses the way of thermal balance to measure the wind speed, that is to use the relationship between the heat loss and the wind speed when the heated wire or film is measured. Wind speed and direction is a familiar concept. We often say that the north wind is blowing or the wind is strong today. The concept of wind direction and wind speed has been involved here. In meteorology, what is the definition of wind speed and direction? Wind direction is the direction of the wind. If the wind blows from the south, it is called the south wind; if the wind blows from the north, it is called the north wind; when the wind direction is irregular, you can add a partial character. The wind speed is the speed of the wind in meters per second. Generally, we grade the wind speed, which is usually divided into 13 grades. They are 0, 1, 2 and There are many instruments for measuring wind direction and wind speed. Beijing inspection and testing company has produced wind speed and direction recorder, which is specially used to measure wind speed and direction, which is called wind direction and wind speed meter. the digital anemometer is a large-scale intelligent wind speed sensor and alarm device specially developed for various large-scale mechanical equipment. The advanced microprocessor is used as the control core in the internal and advanced in the peripheryDigital communication technology. The digital anemometer system has high stability, strong anti-interference Food Packaging Machine ability and high detection accuracy. The wind cup is made of special materials, with high mechanical strength and strong wind resistance. The display case is novel and unique in design, durable and easy to install and use. All electrical interfaces are in accordance with international standards, installation without debugging, suitable for different working environment. Main uses of anemometer: 1. Measure the velocity and direction of average flow. 2. The fluctuating velocity and spectrum of the incoming flow are measured. 3. The Reynolds stress and the velocity and time dependence of the two points were measured. 4. Measurement of wall shear stress (usually by using a hot film probe placed flush with the wall, the principle is similar to hot wire velocimetry). 5. Measure the fluid temperature (measure the curve of the probe linear weigher factory resistance with the fluid temperature in advance, and then determine the temperature according to the measured probe resistance. According to different applications, the hot wire probe is also made into double wire, three wire, oblique wire, V-shaped and X-shaped, etc. In order to increase the strength, metal film is sometimes used instead of wire, and a thin metal film is usually sprayed on a thermal insulation substrate, which is called hot film probe. The hot wire probe must be calibrated before use. Static calibration is carried out in a special standard wind tunnel to measure the relationship between flow velocity and output voltage and draw a standard curve; dynamic calibration is carried out in a known pulsating flow field, or a pulsating electric signal is added to the heating circuit of anemometer to verify the frequency Multihead Weigher Manufacturer response of hot wire anemometer. If the frequency response is poor, corresponding compensation circuit can be used to improve it. Anemometer installation, selection of installation siteOptions: 1. Do not install anemometer near high-energy radar or wireless transmitter. ***Do site survey to determine the local electronic interference, do not install it on a plane with any radar scanning device, and keep a distance of at least 2m; 2. It is recommended to keep a distance from some radio receiving antennas around. Beijing hot bulb anemometer manufacturer_ Price consultation.
