OMC-150 Combined Wind
Speed and Direction Sensor
The OMC-150 comprises a combined in-line wind speed and direction
sensor. The system is robust, corrosion resistant and easy to install. The
wind speed sensor is a rotary-cup type unit, made in stainless steel; rotation of the cup-unit generates pulses with the aid of a proximity switch.
The wind direction sensor is a wind vane type unit made in stainless steel.
The wind vane drives a sin/cosine potentiometer.
