Smart sensors in industry
J.M. Favennec · Journal of Physics E Scientific Instruments · 1987
Technological progress in microelectronics has contributed to the emergence of the concept of the 'smart' or 'intelligent' sensor. A smart sensor will be essentially composed of: transducers; conditioners; an appropriate power supply; an inner computation capability; a communication interface, for digital information; and an identification. The technologies involved for these components are discussed. These include: synergy with local industrial networks; modularity and standardisation; enhanced credibility of data (maintenance assistance, validation of measurements); increased reliability and accuracy; and a reduction in associated costs (particularly wiring).
