Feature: 1. The shell is made of high-quality material with high hardness and external electroplating and spray plastic treatment, which has good anti-corrosion and anti-erosion performance. 2. 0-70m/s range and 0.0875m/s resolution, high precision, accurate measurement and anti-electromagnetic interference treatment. 3. The bottom cable is adopted to completely eliminate the aging problem of the aviation plug rubber pad, and it is waterproof after being used for a long time. 4. High-performance imported bearings, low rotational resistance, accurate measurement, small size and light weight, easy to carry and assemble. 5. Widely used in the measurement of wind direction in greenhouses, environmental protection, weather stations, ships, wharf, breeding and other environments. Specification: Condition: 100% Brand New 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: 0.0875m/s Accuracy: ±0.3m/s Measuring Range: 0-70m/s Dynamic Response Time: ≤0.5s Pulse Output Type Calculation: The transmitter turns 1 circle, outputs 20 pulses For example, when the wind speed transmitter 1S turns 1 circle, the transmitter 1S outputs 20 pulses, which means the wind speed is 1.75m/S. Product Size: Approx. 16 x 16 cm / 6.3 x 6.3 in Weight: Approx. 328g / 11.6oz Package List: 1 x Wind Speed Sensor1 x Cable1 x Screw Kit (4 x Screw, 4 x Nut) Note: 1. The user should not disassemble it by himself, and should not touch the sensor core to avoid damage to the product.2. Keep away from high-power interference equipment as much as possible to avoid inaccurate measurement, such as inverters, motors, etc. When installing or disassembling the transmitter, the power must be disconnected first, and water in the transmitter can cause irreversible changes.3. Prevent chemical reagents, oil, dust, etc. from directly invading the sensor, do not use it for a long time under condensation and extreme temperature environment, and prevent cold and thermal shock.
