Ultrasonic Anemometer (86000 / 86000-SDI)

The YOUNG Model 86000 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. 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 86000-SDI Ultrasonic Anemometer is a specialized version of Model 86000. This model operates similarly to Model 86000 but utilizes SDI-12 (v1.3) serial communication protocol to minimize power consumption.
