The YOUNG Model 81000V Ultrasonic Anemometer measures both horizontal and vertical wind speed and direction.  This sensor features durable, corrosion-resistant construction with three opposing pairs of ultrasonic transducers supported by stainless steel members.  Each sensor is fully wind tunnel tested and calibrated to provide accurate wind measurement.  The standard sensor features RS-232 and RS-485 serial outputs.  Four analog voltage inputs allow data from input devices to be included on the serial output string.  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).
