The creation of a database, with all the associated decisions that must be made, is a job that requires a very good technical understanding of vibration analysis, machinery operational characteristics and good doses of common sense. Always question what you are doing, especially whether or not the desired goals are being achieved and, if not, what other methods might be used to achieve those goals.
A vibration transducer is the instrument that measures or senses the vibration and is commonly referred to as a pickup or sensor. The basic understanding and proper selection of an appropriate transducer is important. This text will not deal in extensive detail with all the different types and technical characteristics of transducers but will attempt only to provide a basic understanding of the important aspects. There are basically three types of transducers commonly used. They are:
