OMC-116 Full metal Ultrasonic wind sensor


Marine meteorological observations require devices designed to withstand the hardest environmental conditions such like heavy vibrations, sea spray, extreme colds, chemical particles etc. With a major track record the Marine and offshore market is the home market for the Observator meteorological product line.

The OMC-116 is a ultrasonic wind sensor based on the time of flight theory. The unit is provided with industrial standard NMEA0183 output and can optionally be provided with 4.20 mA signals. The robust design in sea worthy alu and stainless steel as well the standard available heating makes this unit ideal for the hardest environments. The standard bracket with integrated junction box makes this unit easy to install.
