When you complete this lesson, you will be able to discuss the function of a transducer and describe types of conversions transducers perform. You will also be able to explain the operating principles behind the most common types of transducers. • List various types of transducers and identify their function • Describe I/P transducer operating mechanics • Describe P/I transducer operating mechanics • Discuss the basic principle behind capacitive pressure transducer operation • Define stress and strain; explain how their relationship is used in a variable resistance sensor • Discuss the basic operating principle behind variable frequency sensor operation • Identify the purpose of A/D (analog to digital) and D/A (digital to analog) converters
