Measure pressure based Waves with the Aanderaa Wave Sensors- compact fully integrated sensors for measuring wave and tide conditions

The 5218 wave sensor is designed to be mounted on the Aanderaa SeaGuard top-end plate or connected to SmartGuard using AiCaP CANbus or in other measurement systems using the RS-232 interface.

The 5218R wave sensor sensor is designed for use with long cables by means of RS-422 full duplex interface.

Both wave sensors are based on a silicon piezoresistive pressure sensor. The pressure measurements are sampled and temperature compensated by an advanced Digital Signal Processor.

The wave sensor application areas are in fixed installations, either deployed in a seabed installation in shallow waters, or mounted onto a fixed structure in the upper water column.

The tide measurement is an average of the hydrostatic pressure measured over a time period of 10 seconds to 8 minutes (integration time configurable by the user). The update interval is between 1 second and 255 minutes.

The wave measurements are based on the pressure time series measured over a time period of 64 second to 17 minutes (configurable by the user). The update interval is between 1 second and 255 minutes.

The wave and tide sensor output parameters are:

Pressure
Tide Level
Tide Pressure
Temperature
Significant wave height
Maximum wave height
Mean period
Peak period
Energy wave period
Mean zero crossing period
Wave steepness and irregularity of sea-state

Since all calibration and temperature compensation data are stored inside the sensor, the parameters are by default presented directly in engineering units without any external calculation. The sensor also provides raw data of the pressure and the temperature measurements.

5218 is a compact yet intelligent sensor designed to be used with Aanderaa SmartGuard or SeaGuard as well as in other measuring systems.

Applications:

Navigation safety (Ports & Harbours, Bridges, under keel clearance in fairways)
Marine Operations
Weather forecast and modelling
Climate studies
