Three Cup Anemometer Sensor for Measuring Wind Speed

Three-cup anemometer can measure wind speeds from 0 to 45 m/s, with a maximum wind speed of 50 m/s. It offers multiple output signals, including pulse, 4-20mA, 0-5V, and RS-485, and is powered by DC 5-24V or 12-24V. SUCH wind sensor utilizes electromagnetic induction, and its output signal is linearly related to the horizontal wind speed. It features high measurement accuracy, sensitive response, robust construction, and a wide operating temperature range (-40 to +50℃), making it widely used in meteorology, oceanography, environmental monitoring, airports, ports, laboratories, and industrial and agricultural fields.

Feature

• High-sensitivity 3-cup design for accurate wind speed measurement.
• Carbon fiber wind cups with high strength and low starting threshold.
• Built-in signal processing unit, integrated and waterproof (IP65) structure.
• Flange installation with 5-pin waterproof connector and bottom wiring.
• Suitable for meteorology, marine, environmental monitoring, and industrial/agricultural applications.
