YOUNG Model 91000 Ultrasonic Anemometer

The YOUNG Model 91000 ResponseONE Ultrasonic Anemometer measures wind speed and direction without moving parts. Its IP66-rated construction ensures reliable operation in harsh environments. Each sensor is wind tunnel tested and calibrated to provide accurate wind measurements over a wide operating range. Standard serial output formats include SDI-12, NMEA, and ASCII text. Output can be continuous or polled to save power. Standard RS-232 or RS-485 serial formats allow direct integration with YOUNG displays, marine NMEA systems, data loggers, or other compatible serial devices. The sensor mounts on standard 1-inch IPS pipe. An orientation ring is included that engages with the sensor base to maintain direction when the sensor is removed for maintenance. Termination is via a small clip-style connector in the junction box at the base of the sensor (no special connector required).

The YOUNG Model 91000B ResponseONE Ultrasonic Anemometer features a black housing. All other features are identical to the Model 91000.

The YOUNG Model 91500 ResponseONE Ultrasonic Anemometer includes an internal compass to provide heading for wind direction, making it ideal for mobile or portable applications.
