Conductivity Sensor 4019 A compact fully integrated sensor for measuring the electrical conductivity of seawater. Designed to be mounted on the Recording Doppler Current Profiler RDCP 600. Two versions of this sensor are available, 4019B has enhanced accuracy compared to 4019A, see specifications overleaf. Advantages: • Smart Sensor for easy integration with RDCP • 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 Internal bus, RS-232. • 3 depth ranges available max. 6000 meter Conductivity is a key parameter for in-situ determination of several fundamental physical properties of seawater. For seawater, the ability to conduct electrical current is mostly dependent on temperature and the amount of inorganic dissolved solid. This means that, together with temperature and depth information, a good estimate of the salinity may be determined. 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. Measurements of Conductivity together with Temperature and Depth improves the RDCP 600 virtual sensors, like Salinity and Speed of Sound. These parameters improves the calculated current speed and cell position. Together with the high accuracy Pressure Sensor 3187 the Conductivity Sensor 4019 provides for good CTD meassurement on the RDCP 600. The Conductivity Sensors 4019A and 4019B are based on an inductive principle. This provides for stable measurement without electrodes that are easily fouled and may wear out in the field. Utilization of miniature components has made it possible to integrate all the required electronics. A digital signal processor calculates salinity, density and speed of sound. The salinity and density are calculated according to the UNESCO International Equation of State (IES 80). The sensor can be set to output parameter in RS-232 mode or to the RDCP via the RDCP Internalbus. In RS-232 mode the output parameters are Conductivity in mS/cm, as well as Temperature, Salinity, Density and Speed of sound. In RDCP mode the output parameter is Conductivity in mS/cm. The sensors are available in 3 different depth ranges; 0-300meter, 0-2000meter and 0-6000 meter. The sensor can be mounted directly on the top end plate of the Aanderaa RDCP 600 and connected to the Sensor Board with a short patch cable 4054/4996.
