RM Young 86004 – Ultrasonic Anemometer Heated Analog and Serial Outputs

The RM Young Model 86004 is the next generation 2D Ultrasonic Anemometer. The sensor offers high performance and low power consumption in a compact size. It is ideal for the most demanding wind sensing applications. For extended cold weather use, the 86004 features thermostatically controlled heaters in transducer and housing surfaces.

The sensor features durable, corrosion-resistant construction with sensitive ultrasonic transducers secured in a streamlined molded frame. The 86004 is fully wind tunnel tested and calibrated to provide accurate wind measurement over a wide operating range. The standard sensor includes many useful output options. Analog voltage outputs are provided for wind speed and wind direction. 4-20 mA current signals are available for each channel and are well suited for long cable runs or for industrial settings where noise immunity is important. A variety of serial output formats are also available. These include ASCII text, RMYT (compatible with YOUNG displays) and NMEA formats. The sensor installs on readily available 1 inch (IPS) pipe. Wiring connections are made in a convenient weatherproof junction box; special mounting adapters and connectors are not required. The 86004 does require sensor cable 86070 which is ordered to the length desired.
