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 resistance to electromagnetic interference. Bottom cable design eliminates the aging issue of rubber pads in aviation plugs, ensuring long-term waterproof performance. 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 Power Supply: 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, 20 pulses in 1 second corresponds to a wind speed of 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 screws, 4 nuts) The user should not disassemble the device and must avoid contact with the sensor core to prevent damage. Keep away from high-power interference sources such as inverters and motors to ensure measurement accuracy. Always disconnect power before assembling or disassembling the transmitter, as moisture inside may cause irreversible damage. Avoid direct exposure to chemicals, oil, dust, and similar contaminants. Do not operate for extended periods under conditions of condensation or extreme temperatures. Avoid thermal and cold shock.
