OMC-139 Marine Wind Display

The OMC-139 is a marine wind display for indication of relative wind speed and direction.


Product Description


This display can read in the information of several wind speed and direction sensors and is standard provided with a NMEA0183 output.

The OMC-139 is suitable for flush mount and is housed in a standard 144×144 housing. Besides the normal Obsermet front the unit can also be supplied with a black OEM front, called the Black line.

The “Obsermet” wind display from Observator Instruments BV is a combined display for wind speed and wind direction. The unit incorporates a digital LED indicator for speed and a double ring of 36 LED’s to indicate average direction information and wind variation.

The wind display signals directly from the wind sensor as T.T.Y. or RS422 without the need for additional interfaces.

Daisy chain connectors may be used to transfer wind sensor information to a second wind display. Depending on the capacity and type of cable used, a distance (of) up to 1000 m is possible. The wind display power supply can be set to meet the customer’s specific requirements.

The front panel of the ship-borne wind display shows 0o- 180o on both sides of the scale. Housing available with bracket for ceiling, wall, tabletop mounting.
