OMC-150 /158-2 Intrinsically safe wind sensor (Atex)
Description
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.
