In most measuring systems used in the sea, pressure is a vital parameter. For moored instruments the pressure can be used for determining the actual depth of the instrument. For instrumentation on the seabed the pressure can be used for deriving water level. The pressure is also vital when deriving other parameters as density and speed of sound.
The Aanderaa Pressure Sensor is a compact fully integrated intelligent sensor for measuring the pressure level and the water temperature.
The pressure sensors are based on a silicon piezoresistive bridge sampled and temperature compensated by an advanced Digital Signal Processor. Since all calibration and temperature compensation data is stored internally,pressure can be presented directly in engineering units without any external calculation. The range on both SR10 outputs is user configurable, i.e. confine the range to get optimal resolution.
The Aanderaa Pressure Sensor is also available in a vented version. This means that the sensor is automatically compensated for air pressure. This is done by use of a compensating unit placed in air and an air-pipe in the cable between the sensor and compensating unit.
