Function: The shell is made of high-quality material with high hardness and external electroplating and spray treatment, which has good anti-corrosion and anti-erosion properties. Range 0-70 m / s and resolution 0.0875 m / s, high precision, accurate measurement and anti-electromagnetic interference. The bottom cable is adopted to completely eliminate the aging problem of the rubber pad of the aviation plug, and it is waterproof after long use. High-performance imported bearings, low rotational resistance, accurate measurement, small size and light weight, easy to carry and install. Widely used in wind direction measurement in greenhouses, environmental protection, weather stations, ships, wharfs, farms and other environments. Specification: Item Type: Wind Speed Sensor Material: polycarbonate DC power supply (default): 5-30V DC Transmitter circuit operating temperature: -20 ℃ to + 60 ℃, 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 Calculation of the type of pulse output: The transmitter rotates 1 wheel, it generates 20 pulses For example, when the 1S wind speed transmitter turns 1 wheel, the 1S transmitter sends 20 pulses, which means the wind speed is 1.75 m / s. Product Size: Approx. 16 x 16 cm / 6.3 x 6.3 inches Weight: approx. 328g / 11.6oz Package list: 1 x wind speed sensor 1 x cable 1 x set of screws (4 x screw, 4 x nut) The user should not disassemble it by himself and should not touch the sensor core to avoid damaging the product. If possible, stay away from high-power interfering devices to avoid inaccurate measurements such as inverters, motors, etc. When assembling or disassembling the transducer, disconnect the power first, and the water in the transmitter may cause irreversible changes. Prevent direct interference with chemicals, oil, dust etc. In the sensor, please do not use it for a long time under the conditions of condensation and extreme temperature, and prevent thermal and cold shock.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-DIMEANI official store
