The OMC-150 is an Intrinsically Safe combined wind speed and direction sensor, based on the cup and vane principle. To complete the Intrinsically safe wind system the OMC-158-II is available. A DIN rail mounted Isolator and interface module. Further an Ex junction box is available as OMC-156.
Using a dual wiper potentiometer wind direction is measured without dead-band, while speed is measured using a proximity switch and a code cap. The wind sensor is made from stainless steel and comes with a mounting arm which can be clamped to a mast using two U-Bolts.
The Isolator and interface module is provided with a R422, NMEA output which can be set as 4800 or 9600 baud and can include a VER sentence as well.
Features
