2018-05-02Ultrasonicwind speed and direction indicator is a measurement sensor or measuring instrument that uses the sending of sound wave pulses to measure the time or frequency difference at the receiving end to calculate the wind speed and direction.
2018-03-28Ultrasonic frequency has high wavelength and short wavelength. It has good directivity and can penetrate opaque materials. Ultrasonic flaw detection, thickness measurement, distance measurement, remote control and ultrasonic imaging technology are made by using this characteristic.Ultrasound imaging is a technique that uses ultrasound to render the internal image of an opaque object
2018-02-19Coal-fired power plants install an on-line continuous monitoring system for flue gas, which can effectively monitor and control the emissions of SO2, NOx, smoke and other pollutants, not only reducing environmental damage, but also improving unit operation economy Therefore, it is particularly important to do a good job in controlling the emission of flue gas pollutants and ensure that the continuous monitoring system for flue gas emissions in a power plant operates continuously and reliably.
2018-01-16Although CMOS imagers and infrared sensors have been widely used in smartphones, the question now is whether it is necessary to use radar and ultrasonic sensors in mobile phones and IoT devices.If so, what role will these sensors play?
2017-12-21 Theautomatic monitoring data is collected and stored on each analysis and testing instrument by the control system and then transmitted to the hosting station of each water quality automatic station and the China Environmental Monitoring Station by VPN.Real-time publishing via the Internet.The hosting station can also realize real-time monitoring, remote control, and data collection of the hosted sub-stations through two communication methods: VPN and telephone dialing.The provincial environmental monitoring central stations and other authorized departments can also read the historical monitoring data of each water station from the database of the main station at any time.
2017-11-25On January 28, 2014, at the large wind power test center in Denmark, Vestas V164-8.0MW, the world's largest wind turbine, was put into trial operation, which can produce 8 million watts of electricity per hour, which can meet Electricity demand for 7,500 European homes.
2017-11-25North Star Wind Power Network News: Data collected by Bloomberg's New Energy Economics Research Group (BNEF) shows that the proportion of 20 major economies in the world using solar and wind power has increased by more than 70%.
