Page 5: Introduction
The sensor is often mounted in harsh conditions of the marine and offshore environment and it has proven to be robust and reliable over the years. The OMC-160-3 continues the robust build quality improved with the latest technology, which will make it even more reliable and easier to commission. -
Page 6: Safety
For correct functioning the Observator OMC-160 Anemometer must be installed and commissioned according installation & commissioning instructions by a qualified engineer. The Observator OMC-160 Anemometer has moving parts, which can rotate fast during strong winds. Keep clear of the cup and vane during strong winds! The Observator OMC-160 Anemometer is usually installed at height. -
Page 7: Description
3 Description 3.1 General description The Observator OMC-160-3 is a combined wind speed and direction meter using high accurate non- contact sensors. It uses a rotary cup with 3 cups for speed and a stainless steel balanced vane for direction measurement. It has a NMEA output signal and be combined with all Observator display and MeteoLlink systems. -

2 years. If required, you can adjust this interval. Calibration of wind speed sensor is only possible in a wind tunnel. Observator Instruments B.V. provides calibration services. For address details see chapter 9. Always include the cup unit and the vane unit when the OMC-160 anemometer is shipped for recalibration. -
Page 16: Opening And Closing The Anemometer
6.4 Opening and closing the anemometer The Observator OMC-160 anemometer is designed for low maintenance. The construction is entirely made of non-corrosive materials and all components are conservatively rated. The only components that are likely to require replacement due to normal wear are the precision ball bearings. - Page 17 8. Carefully tap out the bearing assembly from the outside in using a suitable driver (dia 18mm+/-0.5) and hammer or press. 9. Remove small circlip 10. Use a pulley or press to remove bearings from shaft. OMC-160-3 Manual Page 17...
- Page 18 When the bearings are renewed, care should be taken not to apply excessive force on the new bearings. When re-installing the complete bearing housing with the sensor PCB’s, care should be taken that the internal wiring is properly attached, and not touching any moving part.
