The Met One Instruments Model 6400 Visibility Sensor is designed to monitor visibility conditions over a range of 20ft-50miles (6m-80km). The Model 6400 includes both digital and relay outputs. Digital RS232 output at 300-38,400 Baud can be used to indicate the present visibility, provide diagnostic information, and provide access to the configuration and calibration options. The SPDT relay with configurable pull in and drop out set points can provide signals to a VMS or other optional user system.
Met One takes advantage of Belfort’s proven experience with visibility technology in re-designing this new sensor for applications which require high accuracy over an extended range of visibility. These sensors are designed to provide both accuracy and reliability in a cost effective package. T Model 6400 now features ease of field serviceability. Applications include synoptic stations, lighthouses, highways, resort areas, as well as shipboard and other marine platforms.
