OMC-160 Wind speed &
direction sensor
The popular and often used wind sensor OMC-160 is a
combined wind speed and direction sensor, based on the
cup and vane principle. Having chosen for the highest
quality stainless steel materials and internal non-contact
measuring devices, this sensor stands for a long life time,
having the highest accuracies within both the low range as
well as the high range wind speeds. This sensor is com-
monly used within the shipping and offshore industry but
can also be found on many airfields, container terminals
and harbours, along highways and on bridges.
Features:
• High accuracy sensor
• Approved by CAA
• Contact free sensing elements
• High reliability in every environment
• All expoced parts in Stainless steel
• Serial TTY output or NMEA0183 (selectable)
• Cable length up to 1000 m (4 core)
• Heated option available
• NATO stock no: 6660-17-112-7536

GENERAL DATA SUMMARY
POWER REQUIREMENTS
The OMC-160 comprises a combined in-line wind speed ● 8 TO 30 VDC 60 mA
and wind direction sensor. The system is robust, corrosion
resistive and easy to install. The wind speed sensor is a OUTPUTS
rotary-cup type, made UV resistant high quality polycar- ● Currentloop ASCII coded output 20 mA
bonate. Rotation of this cup-unit generates pulses in an ● NMEA-0183 version 2.30
optical encoder. The encoder is directly connected to the
internal microprocessor. The wind direction sensor is a DIMENSIONS, AS PER SKETCH
wind vane type, made from stainless steel. The wind vane ● Weight 6.5 kg

ACCURACY
The wind sensor comes with a vertical mounting bracket ● Wind speed: better than 2% FRO
which includes a junction box and two u-bolds for mast ● Wind direction: better than 3 degrees
mounting ● Speed range: 0,3…75 m/s
Observator has an in-house wind tunnel facility but is also
able to provide a third party, traceable wind tunnel test
certificate. This can be ordered as type number OMC-154
and will be drawn up by the University of Brussels.
The Observator range is in continuous development and so specifications may be subject to change without prior notice
