Function: The shell is made of high-quality material with high hardness and external electroplating and spray treatment, providing good anti-corrosion and anti-erosion properties. Measures wind speed range from 0 to 70 m/s with a resolution of 0.0875 m/s, offering high precision, accurate measurement, and anti-electromagnetic interference. Bottom cable design eliminates the aging issue of rubber pads in aviation plugs, ensuring waterproof performance after long-term use. Equipped with high-performance imported bearings for low rotational resistance, accurate measurement, compact size, and lightweight for easy carrying and installation. Widely used for wind speed measurement in greenhouses, environmental monitoring, weather stations, ships, docks, farms, and similar environments. Specification: Item Type: Wind Speed Sensor Material: Polycarbonate DC Power Supply (default): 5-30V DC Transmitter Circuit Operating Temperature: -20 to 60°C, 0% RH - 80% RH Communication Interface: Pulse output Resolution: 0.0875 m/s Accuracy: 0.3 m/s Measuring Range: 0-70 m/s Dynamic Response Time: 0.5s Pulse Output Calculation: 20 pulses per full rotation of the transmitter. For example, if the transmitter completes one rotation in 1 second, generating 20 pulses, the wind speed is calculated as 1.75 m/s. Product Size: Approx. 16 x 16 cm (6.3 x 6.3 inches) Weight: Approx. 328g (11.6 oz) Package List: 1 x Wind Speed Sensor 1 x Cable 1 x Set of Screws (4 x Screw, 4 x Nut) User Instructions: Do not disassemble the device or touch the sensor core to avoid damage. Avoid proximity to high-power interference sources such as inverters and motors to ensure measurement accuracy. Always disconnect power before assembling or disassembling the transmitter, as internal moisture may cause irreversible damage. Protect from direct exposure to chemicals, oil, dust, and prolonged use under condensation or extreme temperatures. Avoid thermal and cold shock.
