OMC-150 Anemometer with OMC-158-2 Interface Applications Offshore and Industry OMC-150 /158-2 Intrinsically safe wind system The OMC-150 is an Intrinsically Safe combined wind speed and direction sensor, based on the cup and vane principle. • OMC-150 Wind sensor: • High accuracy sensor according W.M.O. To complete the Intrinsically safe wind system the OMC158-2 is available. A DIN rail mounted Zener barrier and • Meets ATEX Directive 2014/34/EU; IEC 60079-0 : 2012, IEC 60079-11 : 2012 and ISO 80079-36:2016 interface module. Further an Eex junction box is available • Equipment category II 2 G • Certificate number DEKRA 13ATEX0119, IECEx DEK Using a sin/cos potentiometer wind direction is measured without a dead-band, while speed is measured using a • OMC-158-2 Wind Sensor Interface Module: proximately switch and a code cap. The wind sensor is • Cable length between sensor 1 km made from stainless steel and comes with a mounting arm • Certificate numbers: KIWA 17ATEX0015 and IECEx which can be clamped to a mast using two U-Bolts. KIWA 17.0005 • Output NMEA0183, RS422 on 4800 or 9600 Baud The Zener barrier and interface module is provided with a • Wind measurement on 4 Hz (standard) or 1 Hz R422, NMEA output which can be set as 4800 or 9600 baud • Compensation (linear wind speed and bracket and can include a VER message as well. correction) may be set on or off • VER message can be included The Observator range is in continuous development and so specifications may be subject to chang
