Transducer Bridges and Amplifiers, selfgenerators or modulators, of course, but the most important here are those having an electrical output, such as amplifiers and bridge circuits, since these are usually required to follow the transducers already discussed. Both are strictly modulators, since they involve a separate power source

Transducers for Length,verviews 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
