Wind Monitor Instrument

Model 6533A

  • Overview

    The Wind Monitor (Model 6533A) is a high performance wind speed and direction sensor manufactured by R.M. Young Company (05103) and designed specifically wide range of wind measuring applications. It combines simplicity and lightweight corrosion resistant construction with a low threshold, fast response, and excellent fidelity.

    The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces a sinewave voltage output where frequency is directly proportional to wind speed. Slip rings and brushes are not used.

    The wind direction sensor is a lightweight vane with sufficiently high damping ratio and low aspect ratio to ensure excellent fidelity in rapidly fluctuating winds. Vane position is sensed by a precision conductive plastic potentiometer. With a known excitation voltage applied to the potentiometer, the output signal is directly proportional to azimuth.
    The instrument is made of UV stabilised plastic with stainless steel and anodised aluminium fittings. All bearings are precision grade stainless steel.
    The instrument mounts on standard 1 inch pipe.
    A micro-power interface circuit (Model 6533B-PCB), housed in a junction box on the mounting post, converts the sinewave to a 5V signal and potentiometer output to a calibrated 2.50 V signal, suitable for connection to the datalogger.

    An 8 core cable (Model 6600F) can be used to connect the instrument to the datalogger.

    If needed, the two channel line driver (Model 6533LD) converts wind speed and wind direction to separate 4-20mA signals.
