Instrumentation engineering is the science of the measurement and control of process variables within a production or manufacturing area. [1] Meanwhile, control engineering, also called control systems engineering, is the engineering discipline that applies control theory to design systems with desired behaviors.
Control is checking current performance against pre-determined standards contained in the plans, with a view to ensuring adequate progress and satisfactory performance. According to Harold Koontz: Controlling is the measurement and correction of performance to make sure that enterprise objectives and the plans devised to attain them are ...
The measurement data is integrated to eliminate a small-scale formation variation from the measurement result. The measurement value is averaged so that each sensor gives one measurement value per one data box which is typically from 5 mm to one centimeter of web width. For a 1 meter wide web, for instance, 100 - 200 measurement values are taken.
ISO 10012:2003, Measurement management systems - Requirements for measurement processes and measuring equipment is the International Organization for Standardization (ISO) standard that specifies generic requirements and provides guidance for the management of measurement processes and metrological confirmation of measuring equipment used to support and demonstrate compliance with metrological ...
There are three common ways that nations convert from traditional measurement systems to the metric system. The first is the quick or "Big-Bang" route. The second way is to phase in units over time and progressively outlaw traditional units. This method, favoured by some industrial nations, is slower and generally less complete. The third way ...
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
A measurement system analysis (MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and data may also have variation ...
Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology". [15] It establishes a common understanding of units, crucial to human activity. [2]
