Basic Transducers for Length

Abstract

In chapter 3 we discussed the classification of transducers and gave a comprehensive summary of the useful physical effects available. Although such overviews may be valuable and interesting, they are not very helpful in designing or selecting a device for a specific application. The remainder of the book will therefore be devoted to practical aspects. The three most important measurement areas are length, temperature and radiation; in each case we will discuss the basic theory where appropriate, but will concentrate on the design and operation of the most useful devices.
