Trang 5As the use of microelectronics became increasingly indispensable in ment and control technology, so there was an increasing need for suitable sen- sors From the mid-Seventies onwards sensors technology developed by leaps and bounds and within ten years had reached the point where it seemed desirable to publish a survey of what had been achieved so far At the request of publishers WILEY-VCH, the task of editing was taken on by Wolfgang Göpel of the Univer- sity of Tübingen (Germany), Joachim Hesse of Carl Zeiss (Germany) and Jay Ze- mel of the University of Philadelphia (USA), and between 1989 and 1995 a series
measure-called Sensors was published in 8 volumes covering the field to date The material
was grouped and presented according to the underlying physical principles and reflected the degree of maturity of the respective methods and products It was written primarily with researchers and design engineers in mind, and new devel- opments have been published each year in one or two supplementary volumes
called Sensors Update.
Both the publishers and the series editors, however, were agreed from the start that eventually sensor users would want to see publications only dealing with their own specific technical or scientific fields Sure enough, during the Nineties
we saw significant developments in applications for sensor technology, and it is now an indispensable part of many industrial processes and systems It is timely,
therefore, to launch a new series, Sensors Applications WILEY-VCH again
commis-sioned Wolfgang Göpel and Joachim Hesse to plan the series, but sadly Wolfgang Göpel suffered a fatal accident in June 1999 and did not live to see publication.
We are fortunate that Julian Gardner of the University of Warwick has been able
to take his place, but Wolfgang Göpel remains a co-editor posthumously and will not be forgotten.
The series of Sensors Applications will deal with the use of sensors in the key technical and economic sectors and systems: Sensors in Manufacturing, Intelligent Buildings, Medicine and Health Care, Automotive Technology, Aerospace Technology, Environmental Technology and Household Appliances Each volume will be edited by
specialists in the field Individual volumes may differ in certain respects as tated by the topic, but the emphasis in each case will be on the process or system
dic-in question: which sensor is used, where, how and why, and exactly what the efits are to the user The process or system itself will of course be outlined and

Trang 6the volume will close with a look ahead to likely developments and applications in the future Actual sensor functions will only be described where it seems neces- sary for an understanding of how they relate to the process or system The basic
principles can always be found in the earlier series of Sensors and Sensors Update.
The series editors would like to express their warm appreciation in the leagues who have contributed their expertise as volume editors or authors We are deeply indebted to the publisher and would like to thank in particular Dr Peter Gregory, Dr Jörn Ritterbusch and Dr Claudia Barzen for their constructive assis- tance both with the editorial detail and the publishing venture in general We trust that our endeavors will meet with the reader’s approval.

Trang 7Manufacturing technology has undergone significant developments over the last decades aiming at improving precision and productivity The development of nu- merical control (NC) technology in 1952 made a significant contribution to meet- ing these requirements The practical application of NC machine tools have stim- ulated technological developments that make the tools more intelligent, and al- lows the machining process to be carried out with higher reliability Today, thanks
to the significant developments in sensor and computer technologies, it can be said that the necessary tools are available for achieving the adaptive control of manufacturing processes, assisted by monitoring systems, which was a dream in the 1950’s.
For the following reasons, monitoring technology with reliable sensors is coming more and more important in modern manufacturing systems:
be-· Machine tools operate with speeds that do not allow manual intervention ever, collisions or process failures may cause significant damage.
How-· Manufacturing systems have become larger in scale, and monitoring of such large-scale systems is already beyond the capability of human beings.
· Increase of labor costs and the shortage of skilled operators calls for operation
of the manufacturing system with minimum human intervention; this requires the introduction of advanced monitoring systems.
· Ultra-precision manufacturing can only be achieved with the aid of advanced metrology and process monitoring technology.
· The use of sophisticated machine tools requires the integration of monitoring systems to prevent machine failure.
· Heavy-duty manufacturing processes with higher energy consumption should
be conducted with minimum human intervention, from the safety point of view.
Trang 8the necessary principles behind these developments We are convinced that the readers of this book, both in research institutes and in industry, can obtain infor- mation necessary for their research and developmental work.
The editors wish to thank the specialists who contributed their expertise and forbearance during the various stages of preparation In addition to the assistance
of the authors, we would like to thank the staff of Wiley-VCH for their support.
