The OMC-506 Barometric Pressure Sensor is a high precision sensor with which Observator Instruments can guarantee an accuracy of ± 0.2 hPa. This sensor is often used within meteo systems on board offshore platforms and various other applications. The OMC-506 is based on a stable, floating piezoresisitive transducer and a micro-processor with build in 16 bit D/A converter.
