Wind Display OMC-138


Observator’s OMC-138 Wind Display is a digital combined display for wind speed and wind direction. The display is housed in a 144 x 144 mm DIN size casing suitable for panel mounting. A tabletop version is available. Any inclination is allowed and no additional control units are required.

Wind direction is indicated within an LED circle. Inside the circle sits a three digit numerical display indicating the wind speed.

A second three-digit display located in the lower right corner provides maximum or minimum wind speed information which can be displayed in m/s, km/h, mph or Beaufort.

Another MENU option is the choice of the averaging interval, which can be set at 2 minutes, 10 minutes or every other user programmed “user” interval.

The unit was primary intended to use with the Obsermet wind sensors, but other most common sensors can be interfaced to the display.
