Aanderaa pressure sensors are compact, intelligent pressure sensors designed for use on Aanderaa Data Instruments dataloggers as well as in other measuring systems.

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.

Selection Guide

Sensing Foil Considerations:
We offer 3 different types of foils on our optodes. The Pst3 & FDO701 sensing foils are protected by an optical isolation layer, making the foil extra rugged and insensitive to direct sunlight. The fast response sensing foil is not equipped with this layer; ambient light intensity higher than 15000 lux may cause erroneous readings. We recommend the more rugged and stable FDO701 foil in applications where fast response is not needed.

*Only use 4330F if fast response oxygen, and/or fast response temperature is needed. The standard sensing foil is protected by an optical isolation layer which makes the foil extra rugged and insensitive to direct sunlight. The fast response sensing foil is not equipped with this layer; ambient light intensity higher than 15000 lux may cause erroneous readings. To avoid potential bleaching the fast response foil should be protected from ambient light when storing the sensor. We recommend the standard foil in applications where fast response time is not needed.

**Please note: All sensors use RS-232 for configuration.
