The WindObserverIS is an Intrinsically Safe anemometer, developed specifically for use in hazardous areas and in particular for offshore applications.
The system combines the latest development in technology with Gill's considerable expertise in the production of solid state anemometers. The Intrinsically Safe WindObserver is a lightweight, robust unit, completely sealed and constructed in stainless steel.
With a low start-up speed (0.01 m/s) and no moving parts, the WindObserverIS Intrinsically Safe anemometer exhibits significant benefits over standard three cup anemometers. This Intrinsically Safe anemometer has Atex and IECEx certification to ensure the wind system may be deployed on a worldwide basis without the need for expensive local certification.
The OMC-150 is an Intrinsically Safe combined wind speed and direction sensor, based on the cup and vane principle. A complete wind set consists besides this sensor of an Eex junction box which is placed nearby the sensor OMC-156, and a Zener barrier interface box OMC-158. Using a sin/cos potentiometer wind direction is measured without a dead-band, while speed is measured using a proximately switch and a code cap. The unit is made from stainless steel and comes with a mounting arm which can be clamped to a mast using two U-Bolts.
