Conductivity Sensor 4319 is a compact fully integrated sensor for measuring the electrical conductivity of seawater. It is designed to be used with SMARTGUARD or SEAGUARD® datalogger using AiCaP CANbus or as stand-alone sensor using RS-232 Advantages: • Smart Sensor for easy integration with SEAGUARD® and SMARTGUARD • Direct readout of engineering data • Internal pressure never exceeds 1 bar therefore electronics and sensors are unaffected by sea depth • Rugged and Robust with low maintenance needs • Output format AiCaP CANbus, RS-232. • 3 depth ranges available maximum 6000 meter Conductivity is a key parameter for in-situ determination of several fundamental physical properties of seawater. Utilization of miniature components have made it possible to integrate all the required electronics. For seawater, 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 salinity may be determined. The Conductivity Sensor outputs data in AiCaP CANbus and RS-232. Output parameters are Conductivity and Temperature in AiCaP and Conductivity, Temperature, Salinity, Density and Sound speed. Data can be presented in Engineering unit or raw data. Salinity is defined as the concentration of dissolved solids. Other important properties of seawater are again dependent on the salinity. Among these are the density and the speed of sound. The SEAGUARD® datalogger and the smart sensors are interfaced by means of a reliable CANbus interface (AiCaP), using XML for plug and play capabilities. The Conductivity Sensor 4319 is based on an inductive principle. This provides for stable measurement with ut electrodes that o are easily fouled and may wear out in the field. AADI is a trademark of Xylem Inc. or one of its subsidiaries. The smart sensors can be mounted directly on the top end plate of the AADI SEAGUARD®, in a String System node or connected to the SMARTGUARD and are automatically detected and recogniced.
