What is process calibration
Process industries are those in which the final product, once manufactured, can’t be separated into its individual components. Examples include the pharmaceutical, petrochemical, electrical power, and semi-conductor industries. Calibrations performed within these industries may happen on a bench in a calibration laboratory; they can also happen out in the plant or in the field. We refer to both bench and field calibration practices that happen within process industries as “process calibration.”
Application
Process calibration professionals can include metrologists, instrumentation and control (I&C) or electrical and instrumentation technicians, electrical technicians, or engineers. Some of these professionals work in a metrology lab. Others work in an instrument shop, and still others work out on the plant floor.
