About Process measurement and instrumentation
The course aims to introduce the students the function and role of process measurement and instrumentation in a industrial processes and manufacturing environment. Introduction to Control Systems • Open-loop and closed-loop control systems • Typical processes that measure pressure temperature, flow, and level. System Components • Sensing devices to their uses in measuring pressure, level, flow and temperature. • Transmitters, receiving devices, controllers, valves and other process instruments • ISA symbols on a process and instrumentation diagram Principles of Pressure Measurement • The basics of pressure measurement devices. • Manometers, bourdon tubes, diaphragms, capsules, bellows, and strain gauges. Principles of Level Measurement • level measurement differentiate between low-pressure and high-pressure level measuring methods • Uses of capacitance, displacer, and reluctance probes in measurement and instrumentation; • Methods of level measurement such as infrared, radioactive, and ultrasonic systems will be discussed. Principles of Temperature Measurement • Thermocouples, RTDs, thermistors, • Filled thermal systems, bimetallic devices, and infrared sensors. Principles of Flow Measurement • basics of flow measurement • Differentiate between methods of flow measurements • Flow measuring devices & applications. Process Systems • The standards for pneumatic and electrical transmissions and relate these to applications. • The function of instrument loops in a typical industrial application.
