Base Knowledge
Physics. Termodynamics. Fluid Mechanics.
Teaching Methodologies
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. Distributed evaluation involves two components: i) evaluation of theoretical concepts (evaluated by 2
mini exams about instrumentation, A (25%), and a 3rd exam about control, B (45%)), ii) lab exercises made in group in practical classes, C (20 %)
and by a research work on the selection of an instrument or on LabView to develop a VI, with oral presentation, D (10%). The final classification is
obtained by adding the contributions of the various components in a scale of 0 to 20 (0.25xA+0.45xB+0.20xC+0.10xD).
Learning Results
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.
