The OMC-138 is the standard wind display for land applications and fixed offshore objects. The display can be provided with industrial standard outputs either as standard or as an option (4..20 mA) The OMC-138 is suitable for flush mounting and is housed in a standard 144x144 housing.
Wind direction is indicated within a double LED circle, with the four wind directions. Each circle consists of 36 LED's for average direction and wind variation. Inside the circles a three digit numeric display indicates the wind speed. A second three-digit display located in the lower right corner provides maximum or minimum wind speed information. The wind information can be displayed in m/s, km/h, mph or Beaufort. Users have the option of what averaging interval they wish to view, which can be set at 2 or10 mins. | |
