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.
