Structures for self-monitoring of measurement systems

Self-monitoring of measurement systems is usually restricted to the electrical part. In practice, however, most disturbances occur at the interface between the primary front-end sensor and the measurement object; this interface usually is not monitored. A distinction has to be made between self-monitoring measurement systems for product automation and for process automation. In process automation, systems are very complex, only one configuration exists, and engineering effort is limited. As a simple solution without much engineering, measurement systems should be related to or coupled with neighboring actors. Static behavior is sufficient, without any need for complex dynamic analysis.
