Conductivity Sensor Aanderaa 5860

Conductivity Sensor

Salt Water Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring the conductivity of water. The conductivity of saltwater 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 the 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, the 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 salinity. Among these are the density and the speed of sound.
The Aanderaa Conductivity Sensor is based on an inductive principle.

The Smart sensor, including 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.

Aanderaa Conductivity Sensor 5860

The Aanderaa Conductivity Sensor 5860 is a compact fully integrated sensor for measuring the electrical conductivity of seawater. 5860 is designed to be used as a stand-alone sensor using RS-232. For other applications with a 10-pin lemon insert and either AiCaP, RS-232, or RS-422 please refer to Conductivity Sensor 4319/4419.

The Aanderaa Conductivity sensor 5860 is based on an inductive principle. This provides for stable measurement without electrodes that are easily fouled and may wear out in the field.

The utilization of miniature components has made it possible to integrate all the required electronics.

The output format for 5860 is RS-232. Output parameters are conductivity, temperature, salinity, density, and sound speed. Data can be presented in engineering units or raw data.

Aanderaa offers an easy to use configuration software; AADI Real-Time Collector, both for configuration but also logging of data.

As an alternative to this software, you may also use a terminal software like Terra Term or Hyper Terminal.
