OMC-118 Ultrasonic wind sensor

Description

OMC-118 Ultrasonic wind sensor is used in cases an ultrasonic wind sensor is required. As Commercial Of The Shelf sensor, Observator has supplied this stainless steel instrument to several Navies. Other application were Observator applied this sensor are in general marine and offshore applications as well in several tunnels.

The OMC-118 can be connected to all Obsermet equipment like data loggers, signal conditioning units and displays using the NMEA or Polar format. The OMC-118 which has a standard 0..65 m/s is optionally also available in a 0..75 m/s range.
