Salt water Conductivity Sensor

Salt Water Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring water conductivity. Measuring conductivity of salt water is a key parameter for in-situ measurements of several fundamental physical properties of water.

For saltwater, the ability to conduct electrical current is mostly dependent on temperature and the amount of inorganic dissolved solids. This means that, together with
temperature and depth information, a good estimate of the water conductivity or salinity may be determined by measuring conductivity of water with an Aanderaaa conductivity sensor. Salinity is defined as the concentration of dissolved solids. This means that, together with temperature and depth information, a good estimate of the salinity may be determined. By using the inductive principle, stable measurement can be obtained without utilizing electrodes that are easily fouled and may wear out in the field.

Salinity is defined as the concentration of dissolved solids. Other important properties of saltwater are again dependent on the salinity. Among these are the density and the speed of sound.
The Aanderaa Conductivity Sensor is based on an inductive principle.

The Smart sensor, inculding the conductivity sensor can be mounted directly on the top-end plate of the Aanderaa SmartGuard datalogger, in a String System node or connected to the SmartGuard datalogger and hence automatically detected and recognized.

Ocean Currents

Ocean water currents are driven by winds, tides and density differences. The ocean circulation regulates the earth's climate by transporting heat. The flowing water affects offshore and coastal construction and also carries particles, animals, plants, nutrients, pollutants and dissolved gases. The acoustic doppler technique has become the preferred technology for most users measuring ocean current, because it is robust, needs no calibrations, can be used for both point (RCM) and profiling (Acoustic Doppler Current Profiling) measurements and is basically insensitive to fouling.

Pressure Sensor

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

Ocean Waves

Surface waves are formed by winds either locally as "wind waves" with shorter periods, or further away as “swell" with longer periods. A rare case of extremely long period of ocean waves are tsunamis from e.g. earthquakes and landslides. Because ocean waves can travel far and can contain high energy it is important to measure ocean waves to understand their impact on shipping fishing, tourism, constructions, shorelines, water mixing, sediment resuspension, gas exchange etc.

Temperature Sensor

Aanderaa water temperature sensors are compact, intelligent sensors designed for use on Aanderaa's Dataloggers and as stand-alone units.
