Traceable And Efficient Calibrations In The Process Industry

Today's modern process plants, production processes, and quality systems, put new and tight requirements on the accuracy of process instruments and on process control. Quality systems, such as the ISO 9000 and ISO 14000 series of quality standards, call for systematic and well-documented calibrations, with regard to accuracy, repeatability, uncertainty, confidence levels, etc.

Does this mean that the electricians and instrumentation people should be calibration experts? Not really, but this topic should not be ignored. Fortunately, modern calibration techniques and calibration systems have made it easier to fulfill the requirements on instrumentation calibration and maintenance in a productive way.

However, some understanding of the techniques, terminology and methods involved in calibration must be known and understood in order to perform according to International Quality Systems.
