Instrumentation

Physics. Termodynamics. Fluid Mechanics.

Lectures for presentation of the formal bases of the course unit, accompanied by show sessions of real instruments and problems solving classes, and practical classes involving laboratory work. The student has to choose one of two assessment methodologies: the distributed evaluation or assessment by a single exam. 

Raise awareness on the importance of metrology. Know the industrial instrumentation associated with the measurement of temperature, flow, level, pressure, viscosity, density and humidity of a gas. Recognize how a biospecific interaction can be used in the development of biosensors. Describe and critically evaluate the application of a particular biosensor. Ability to use the knowledge in the field of instrumentation and control, in order to select and integrate this knowledge in a real problem measurement of control variables associated with the operation of biological processes. Ability to program in the LabVIEW graphical platform and build a virtual instrument for data acquisition. Ability to think about systems in open loop and closed loop feedback control and take appropriate actions to improve the control’s quality and stability. Ability to identify the instrumentation and control loops from an industrial plant in a P&ID diagram.
