Sensors and Transducers,ical in nature, and a transducer. The transducer has the function of converting the input to an electrical form for convenient transmission, data storage or analysis. In many pressure transducers for example, the pressure being measured is made to deflect a mechanical element such as a diaphragm, be

Signal Conversion,ts are usually measured by sensors which give an analogue voltage or current output. There are of course exceptions. For example, many optical displacement sensors operate by sensing the motion of patterns of dark and light stripes as discussed in chapter 2. The output from such devices may be treat

Correlation and Spectral Analysis,s often taken without much thought. Consideration should first be given to alternative methods. There are a number of excellent analysis techniques available for investigating the characteristics of time domain data. In this concluding chapter we shall introduce correlation, which is probably the be

The Performance of Instrumentation Systems,Instrumentation is a subject which is of fundamental importance to engineering, and to almost all of the practically-based sciences. From the student undertaking a laboratory investigation to the operators of a nuclear power plant, accurate measurements are an essential prerequisite to the understanding and control of all physical processes.
