FirstRate FST200-1002 Wind Speed Sensor, 0.5-50m/s, 4-20mA Output, 1.5m Cable

The sensor provides a standard 2-wire 4-20mA current loop output. You connect the positive (typically red) wire to your 12-30VDC power supply positive, and the negative (typically black) wire to the positive input of your 4-20mA receiver (PLC analog input, data logger, etc.). The receiver's negative input is then connected back to the power supply negative, completing the loop. The sensor acts as a variable resistor in the loop, modulating current between 4mA (0.5 m/s) and 20mA (50 m/s).

Yes, the FST200-1002 is designed for outdoor use. Its IP65 rating protects it against dust ingress and low-pressure water jets from any direction, making it suitable for rain and wet conditions. The polycarbonate and nylon housing offers good corrosion resistance. However, for prolonged submersion or extreme hurricane-force winds, consult the manufacturer for specific installation guidelines.

The sensor has a low starting wind speed of 0.5 meters per second (m/s). Its specified accuracy is ±3% of the full-scale range (50 m/s), which translates to a maximum error of ±1.5 m/s across its entire measurement span. This performance is sufficient for most industrial monitoring, safety, and environmental data collection applications.

The sensor is pre-calibrated at the factory and is typically ready for use. The wide operating voltage range of 12 to 30 Volts DC allows for flexible integration into various industrial power systems, including 12V, 24V, or other standard DC supplies within that range. The built-in fault-tolerant and surge protection circuitry helps prevent damage from voltage spikes or wiring mistakes.
