Abstract :
Industrial Process Instrumentation. Instrumentation has been defined in many ways and a particularly good definition appears in the September 1964 issue of IEEE Transactions on Industrial Electronics and Control Instrumentation. In that issue, A. J. Hornfeck says, “Instrumentation may be defined as the technology of communicating with the physical process to obtain quantitative measurements of the behavior of the process and of using these measurements to understand and control the process.”
