Model H-375-Sonic
Ultrasonic Wind Sensor
The Model H375-Sonic is a proven ultrasonic
technology providing wind speed and direction
data via one serial or two analogue outputs. To
confirm correct operation, outputs are
transmitted together with an instrument status
code.
With a robust, corrosion-free polycarbonate
housing, this small, lightweight wind sensor is
recommended for use in harsh environmental
conditions and is particularly suited to marine &
offshore (ships, data buoys) and land based
installations. The H375- Sonic has no moving
parts, offering maintenance-free operation in a
wide range of applications.
Key Features
The sensor features durable, corrosionresistant construction with opposing pairs
of ultrasonic transducers secured in a
streamlined molded frame. The H375-Sonic
is fully wind-tunnel tested and calibrated to
provide accurate wind measurement over a
wide operating range. Voltage outputs are
provided for wind speed and wind direction.
A variety of serial output formats are also
available on the standard sensor. The
sensor installs on readily available 1 inch
(IPS) pipe.
