>>3-Axis Ultrasonic Anemometer Model 81000

>>MODEL: 81000
>>MODEL: 81000V

The YOUNG Model 81000 Ultrasonic Anemometer is a 3-axis,no-moving-paarts wind sensor. It is perfectly suited ofr applications requiring fast response, high resolution and three-dimensional wind measurement.

     The sensor features durable corrosion-resistant construction with 3 opposing pairs of ultrasonic transducers supported by stainless steel members. The transducers are arranged so that measurements are made through a com-mon volume, A fast, 160 Hz internal sampling rate ensures superior measrement resolution. Output rates from 4 to 32 Hz may be selected. Each 81000 is individually wind-tunnel tested and calibrated to compensate for wind shadow effects of the support structure.
    Model 81000 features four voltage Output channels. Senial RS-485 outputs are avaliable as well. For applications requiring synchronized analog measurements, Model 81000V includes four voltage input channels instead of voltage outputs. Wind sonic temperature and volt-age input data are transmitted seriallly. For each model, a variety of preset or custom output format options may be selected by the user.
    Both models install on standard 1 inch pipe. Wiring connections are housed in a convenient weatherproof junction Box.
