Trends in the development of sensors in chemical engineering . The present article surveys the state of the art and future developments of sensors, mainly in the chemical industry. Existing requirements are compared with solutions becoming possible by means of present or developing new technologies and measuring concepts. The discussion covers a wide range, from sensors for classical state variables to sensors for the determination of concentrations and biotechnological variables. It includes data communication and modern process control. Among new technologies microelectronics and integrated microcomputers are rated highest; in addition possible uses of electrooptics and glass fiber techniques are mentioned as well as solid state and biochemical components. Within the new concepts, measurements based on modelling and multisensor systems have gained a firm position in practical applications.
