AWS430 is an automatic weather station specially designed for maritime environments such as ports, ships, and offshore platforms. The AWS430 contains either a water proof outdoor enclosure with various mounting options or 19″ equipment rack unit. Outdoor enclosure is designed to withstand the salty and wet conditions that prevail aboard ships and platforms as well as the freeze/thaw conditions experienced in extreme-weather environments. It is also able to endure vibration and shock. Wide Range of High Quality Measurements The basic weather parameters measured are wind speed and direction (relative wind, true wind, upwind), atmospheric pressure, air temperature, and humidity. Additional sensors can be installed for measuring other parameters, including water temperature, duration of rain and sunshine, global and long wave radiation, amount of precipitation, cloud heigh, visibility, wave height, water level, water current and ship motion. AWS430 has built in calculation for many meteorological and statistical parameters such as dew point temperature. Flexible Integration To obtain the most accurate true wind calculation, the vessel’s own gyrocompass and navigation system can be used to provide the required heading and ship speed, direction, and location information. However, an optional GPS compass can also be integrated into the system. The system fully supports all the requirements for data communication as specified in NMEA 0183 and IEC 1162-1. When system is equipped with several wind sensors the most accurate wind data is selected by built in selection algorithm. Several different satellite communication options, such as Iridium and Inmarsat-C, are also available. Self Diagnostics and Constant Data Availability Built-in algorithms test each measurement to ensure data quality. For every parameter, tests are carried out on the minimum and maximum readings as well as step limits. Various parameters are also cross-checked. The built-in testing system continuously monitors the sensors, providing an immediate alert in case of a fault. Designed for Demanding Maritime Applications All the materials of the AWS430 have been selected for their ability to withstand the harsh, corrosive conditions experienced in maritime environments. The AWS430 has successfully passed a wide variety, of environmental, electrical, vibration and shock tests. All test specifications comply with both the Lloyd’sLloyds’ Register approval system and the IEC 60945 international maritime standard.
