Transducers and microprocessors in oceanographic applications

R.G.P. Desai, E. Desa


Transducers used for the sensing of the ten most measured marine parameters have been described in this paper. The ten parameters have been classed under 5 sensor types, namely temperature, pressure, salinity, currents and waves. For each sensor type, attention has been paid to the most promising candidate for the years to come, and an example of a complete instrument using such sensors has been highlighted, especially the contributions that modern day programmable logic can make to instrumentation systems. The conclusion highlights the areas of transducer technology that the country can enter to benefit the several communities of oceanographers, meteorologists and users in the oil industry and ports and harbours
