Abstract :
A soft-sensor, or virtual sensor, is a system designed to substitute the momentary or permanent unavailability of a sensor in a plant. This substitution may be required because the actual sensor has failed or because it has been removed for maintenance. It may also happen that the real sensor is used in a time-sharing way. Topics involved in the use of soft-sensors including new developments are reviewed. Experimental results obtained from applications to industrial plants are given, and related pending R&D subjects are presented
