||A 2-axis, no-moving-parts wind sensor. It is ideal for general meteorological applications requiring accurate and reliable measurement. Measurement results are available as calibrated voltage output signals or serial data using RS-232, RS-485, or SDI-12 connections. Serial formats may be selected for direct connection to YOUNG Wind Tracker displays, marine NMEA systems, SDI-12 data loggers, and ASCII serial communication programs. The sensor measures wind based on the transit time of ultrasonic pulses between four transducers. Air flow alters the transit time which is used to calculate flow velocity. Wind direction is determined from relative velocities along each acoustic path. The sensor is constructed using UV-stabilized thermoplastic, stainless steel, and anodized aluminium for superior environmental resistance. It is easily mounted on standard 1 inch (IPS) pipe. An orientation ring preserves mounting position when the sensor is removed. Continuous output or polled operation may be used.
