Maintaining an Effective Calibration Program for Industrial Process Instrumentation

摘要

Process industry membership in NCSL has grown rapidly in recent years due to the increasing need for large scale, high quality calibrations outside the standards laboratory. This paper profiles the calibration program at one large chemical manufacturing site and uses this as a framework to give general answers to the following questions: What are some typical obstacles to implementing and maintaining an effective calibration program for process instrumentation? How can these obstacles be overcome? How can you improve or better document the value of your calibration program?
