The OMC-116M Ultrasonic wind speed and direction sensor comes standard with an industrial mounting bracket provided with 2 U-bolts suitable for mast mounting (max 65 mm dia.). An integrated junction box allows easy connection of sensor signal and power supply using standard cabling. The internal heater should be powered separately if used. The sensor can be configured to enable or disable the heater.
In applications where heating is not required (and hence disabled), the OMC-116 can be powered directly from an Obsermet display or data logger. In cases where the heater is to be used (advised in cases where temperatures below zero may be expected) an external 24Vdc power supply should be used with a capacity of not less than 250 watts.
The unit comes complete with a calibration certificate at no extra cost. Although the unit is maintenance free and does not need re-calibration, it is possible to return the sensor to Observator for a re-calibration if required.
