An overview of the
Easy to wind direction ultrasonic wind speed sensor is a wind speed and direction of research and development on the basis of the principle of ultrasonic measuring instruments, using sonic pulse of sending, measure the time or frequency at the receiving end (doppler shift) difference is to calculate wind speed and direction, the sensor can measure wind speed at the same time, the instantaneous value, support the current, voltage signal output and RS485, NB - IoT, LoRa, GPRS and Ethernet transmission way,
Machine shell adopt ABS material, with light weight, no moving parts, the characteristics of strong and durable, and does not need maintenance and calibration, can output wind speed and direction at the same time, with computer, data collector or other with RS485 or analog output conform collection devices,
1, the function feature
No start wind speed limits, zero wind speed work, 360 without Angle limitation, can get wind speed at the same time, the direction of the wind data;
Reasonable design, sealed performance is good;
No moving parts, wear small, long service life;
Using random error identification technology, under the high winds can also ensure low discretization error of measurement, make the output more smoothly;
Engineering plastics shell, portable to carry, install and remove easily;
Signal access convenient, support two kinds of digital and analog signals;
Don't need to maintenance and calibration,
2, the scope of the
Widely used in meteorology, Marine environment, airport, port, laboratory, industrial and agricultural and transportation in the areas of wind speed and direction measurement,
3, work, storage condition
Working temperature: - humidity 40 ~ 85 job: 0 ~ 100% RH
Storage temperature: - 40 ~ 125 storage humidity: <80% (no condensation)
The working principle of
Ultrasonic wind is an application of ultrasonic technology in gas medium, it is to use the speed of ultrasonic wave in air is the influence of the air flow (wind) to measure wind speed, wind cup or rotor with conventional anemometer compared the characteristics of this measurement method is no mechanical moving parts, the whole wind system belongs to no inertial measurement, so it can accurately measure the natural wind gusts in pulsating high frequency components,
Ultrasonic wind speed and direction sensor using four ultrasonic probe cycle to send and receive ultrasonic in two-dimensional plane, through the ultrasonic wave in air jet lag to measure wind speed and direction,
