The RK100-01 Wind Speed Sensor (MTI.AWS.RK.100-01) is specifically designed to accurately and reliably measure wind velocity under the adverse environmental conditions. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are build-in, it outputs voltage and current signals by electromagnetic induction, the value and horizontal wind speed are linear relation.Shell is made of high-strength aluminum alloy, the wind cup is made of 304 stainless steel, the PCB board is painted with anti-corrosion coating, featured with water proof, corrosion resisting. Inside and turning position have sealing rings with nice sealing function, stop water, salt fog and dust getting in.The RK100-01 wind speed sensor has good performance in harsh environment. The metal wind speed sensor cup anemometer is a sophisticated and highly efficient device designed to accurately measure the velocity of wind. The wind cup anemometer features three or more vertical cups fixed on horizontal arms that rotate when exposed to the force of the wind. Constructed from durable and reliable materials such as metal, this sensor excels in providing precise measurements even in harsh weather conditions. The rotating cups generate mechanical energy which is converted into electrical signals by integrated sensors within the device. These signals are then processed and translated into accurate readings of wind speed. With its sturdy construction and advanced technology, the metal wind speed sensor proves to be an indispensable tool for meteorological professionals, researchers, environmentalists, engineers, and many other fields requiring precise knowledge of atmospheric dynamics.
