Condition monitoring means »the use of specialist equipment to measure the condition of equipment. Vibration analysis, tribology and thermography are all examples of Condition Monitoring techniques«. In addition, condition monitoring can a lso mean the condition of a process, e.g. in chemical industries. In both cases condition does not mean the achievement and / or verification of some critical values, it means a more general view on the process or equipment like the age (degradation) of oil, the state of a cleaning process etc.. Most of these parameters are fuzzy measured, which may be evaluated by special multivariate algorithms directly from the set of measurement values. A well known example is the evaluation of roller bearing faults via acoustic spectroscopy. Electrochemical sensors show the way to gather broad information about the condition fluid in chemical processes and equipment like lubricants. In many cases also electrochemical spectroscopic methods may be used to get enough information about the fluids. In the following chapters the electrochemical sensors and the signal evaluation methods were described and on the basis of some applications illustrated.
