Description

This three-cup anemometer operates on the principle of converting rotational speed, induced by wind, into a precise 4-20mA analog current signal. The current output is inherently resistant to voltage drop over long cable runs, making it ideal for remote monitoring stations and industrial SCADA systems. The sensor’s internal signal conditioning circuitry ensures a linear relationship between wind speed (0-30 m/s) and the output current, providing a reliable measurement for process control and data acquisition.

Constructed with a precision-cast aluminum alloy body and cups, the sensor is engineered for long-term exposure to harsh weather conditions, including rain, salt spray, and UV radiation. The integrated military-grade plug and sealed internal electronics provide a high degree of waterproofing and corrosion protection, ensuring parameter stability and reliable performance across its extended operating temperature range of -40°C to +80°C.

Frequently Asked Questions

What is the power supply requirement for this 4-20mA wind sensor?

The sensor requires a DC power supply between 12V and 24V, connected in series with the current loop. The positive supply terminal connects to the sensor's power input, and the 4-20mA signal is read as a voltage drop across a precision resistor (e.g., 250Ω for a 1-5V signal) placed between the sensor's output and ground. Ensure the power supply GND and your data acquisition system's GND are connected for a common reference.

How do I convert the 4-20mA output to a wind speed reading?

The 4mA signal corresponds to 0 m/s (or the startup threshold), and 20mA corresponds to the full-scale 30 m/s. To read it with a microcontroller like an Arduino, place a precision resistor (commonly 250Ω) in series with the current loop to convert the current to a voltage (1V to 5V). Then, use an analog input to read this voltage and map it linearly: Wind Speed (m/s) = ((Read_Voltage - Voltage_at_4mA) / (Voltage_at_20mA - Voltage_at_4mA)) * 30 m/s.

Is this sensor suitable for permanent outdoor installation?

Yes, its construction is specifically designed for permanent outdoor use. The aluminum alloy housing and cups provide excellent corrosion resistance, and the internal electronics are sealed and protected, offering a high degree of waterproofing (effectively IP65). The military-grade cable connector further ensures a reliable seal against moisture and environmental contaminants for long-term reliability.

What is the maximum cable length I can use with this sensor?

The 4-20mA current loop output is highly resistant to signal degradation over distance. The specification states a transmission distance of less than 1000 meters. For runs approaching this maximum, use a high-quality, shielded twisted-pair cable to minimize noise pickup and ensure stable power delivery from your 12-24V DC source at the sensor end.
