OMC-150 / 158-2 Intrinsically Safe Wind Sensor (Atex)

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-158-2. 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.
