Sensor technology, like micro-electronics and gene technology, has developed into a key technology. They make control systems sensitive, supply status and position values in machine structures and allow equipment to react with a certain degree of intelligence.

In short, they relieve the human component in production of a small part of the monotonous thinking and monitoring role. In fact, some processes are not possible without sensors. The number of components, including pneumatic components, with various sensors already integrated will increase in the future.

This volume is aimed at practicians and is a concise, illustrated introduction to the main areas in contact and contactless acquisition of up-to-date process data. It is structured according to typical task areas, shows numerous applications and also provides very brief explanations of important physical contexts.
