OMC-150/158 Intrinsically safe wind sensor

  • The OMC-150 comprises of a combined in-line wind speed and direction sensor. The system is robust, corrosion resistive and easy to install. 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.

    Inside the safe zone the sensor is connected to the OMC- 158 Zener Barrier Box. This consists of an aluminium case containing the interface printed circuit board and three safety barriers. This is the standard Obsermet current loop signal with ASCII information, provided at 300 baud.
