Learning Course on Instrumentation and Control Engineering

Classify instrumentation loops as open loop and closed loop, showing open loop from field to control room and no feedback, with examples like electric bulbs, TVs, remotes, and washing machines.

Explore closed-loop instrumentation from field signals to the control room, and explain how feedback drives control actions via analog i/o to the final element in systems like thermostats and turbines.

Explore static properties in flow engineering, including pressure and density, how heating and cooling affect density, the density of gases, steam, and air, and specific gravity and flow meter fundamentals.

Explore dynamic properties and dynamic pressure from fluid movement. Identify laminar, transitional, and turbulent flows in internal and external flows using Reynolds number, the ratio of inertial to viscous forces.

Explore Bernoulli's principle and its role in flow measurement for gases and liquids, linking energy per unit volume to velocity changes and pressure drops at restrictions.

Explore flow measuring devices across differential pressure, mass flow, velocity, and open channel types, including orifice plates, venturi tubes, pitot tubes, rotameters, and magnetic, ultrasonic, turbine, and vortex meters.

Explain open and closed tank measurement with differential pressure transmitters, where open tanks reference atmospheric pressure and closed tanks cancel gas pressure to reflect hydrostatic head and 4–20 ma output.

Explore level measurement concepts for dry and wet lake systems, detailing transmitter connections with a three volt manifold, isolation valves, knockout pots, and drain valves, plus condensate management.

Explore level compensation during transmitter calibration and zero separation below the tank base, using hydrostatic head to bias the transmitter for 4–20 mA output at empty and full conditions.

Master level compensation during transmitter calibration by applying zero elevation to offset negative differential pressure from the wet leg, ensuring accurate level readings.

Explore pressure measurement concepts, including definitions, types (absolute, gauge, vacuum, atmospheric), Bourdon tube gauges, and essential units and conversions.

Learn temperature fundamentals, scale conversions, and how thermocouples, RTDs, and thermowells enable accurate industrial temperature measurement with transmitter integration.

Classify hazardous areas into zone zero, zone one, and zone two based on continuous, intermittent, and abnormal flammable atmospheres, with room and petrochemical examples illustrating classifications.
