The YOUNG Model 86004 Ultrasonic Anemometer measures horizontal wind speed and direction. This lightweight and compact sensor features durable, corrosion-resistant construction with sensitive ultrasonic transducers secured in a streamlined molded frame. Heating elements are thermostatically controlled to activate under low temperature conditions. Each sensor is fully wind tunnel tested and calibrated to provide accurate wind measurement over a wide operating range. The standard sensor features RS-232 and RS-485 serial outputs in a variety of formats. 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.* The sensor mounts on a standard 1-inch IPS pipe. A mounting orientation ring is included that engages with the base of the sensor to retain orientation when the sensor is removed for maintenance. Terminations are made in a junction box at the base of the sensor by small clamp-style connectors (no special connectors are required).
The YOUNG Model 86004-SDI Ultrasonic Anemometer is a specialized version of Model 86004. This model operates similarly to Model 86004 but utilizes SDI-12 (v1.3) serial communication protocol to minimize power consumption.
An optional Bird Wire Assembly, Model 86052, may be use to discourage birds from perching on the sensor. To achieve optimal performance this assembly must be installed prior to calibration (when used).
