Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)
To give the trainee the knowledge necessary to understand the laws of physics on which the operation of the transducers is based
used to measure the process variables, with incidence on temperature and flow variables. Measurement of volumetric flow and mass flow rate. Study of the operation and characterization of control valves, actuators and positioners.
Syllabus
1 - Temperature Measurement
Definition and units. International Scale. Absolute temperature. Pressure and bimetallic liquid thermometers. Thermocouples; thermostats
and thermistors. Principles of operation, particularities, installations, applications and measurement circuits. Reference to
non-contact thermometers.
2 - Flow Measurement
Meaning of volumetric and mass flow. Units. Basics of hydrodynamics. Bernoulli's Theorem. Pressure flow measurement
differential: The calibrated orifice and Venturi. Applications in the measurement of liquids, gases and steam. Area Flow Meters
variable: the rotor. Electromagnetic flow meters; Vortex; ultrasounds etc. Volumetric flowmeters: turbines and oval wheels.
Coriolis mass flowmeter.
Measurement of flows in open channels. Installation and its peculiarities. Calibration.
3 - Final Control Elements
The control valve: constitution and operation, types and characteristics, actuators, positioners and electropneumatic converters.
Specification and choice of control valve. Definition of Cv, Kv and loss of load. Electric servomotors and other actuators.
Demonstration of the syllabus coherence with the UC intended learning outcomes
This UC guarantees the coherence of the contents addressed since they arise following the lecturing of the UC of Transducers and Instrumentation, consolidating the knowledge based on the accomplishment of the above mentioned laboratory demonstrations.
Teaching methodologies
Laboratory demonstrations:
Pt100
Thermocouples
Test bench of flowmeters
Valve
Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes
This UC guarantees the coherence of the contents addressed since they arise following the lecturing of the UC of Transducers and Instrumentation, consolidating the knowledge based on the accomplishment of the above mentioned laboratory demonstrations.
Assessment methodologies and evidences
The use of this curricular unit can be obtained through two evaluation methods: continuous assessment or examination evaluation.
Continuous evaluation
Continuous assessment includes 2 tests with a weighting of 50%, each, in the final grade. Access to continuous assessment requires the attendance of at least 85% of classes until the first test and another 85% between the 1st and 2nd tests.
After the end of the school year there is a period of continuous assessment recovery and a one-time examination period. The recovery of the continuous evaluation is not used to make grade improvement and the student only admits the recovery if he has obtained a grade of continuous evaluation of less than 10, in this case only improving the grade of one, and only one, of the tests where he has obtained a rating lower than 9.5 values.
Examination evaluation
Students who choose not to take the continuous assessment, or who have opted for it, have not obtained approval, may take the exam.
Calculation of final grade
In the case of the evaluation by tests, the final grade corresponds to the weighted sum of the scores obtained in each one of the continuous assessment moments: NF = 0,5 * T1 + 0,5 * T2 where T1 and T2 correspond to the classifications obtained in each one of the tests.
In the case of the examination evaluation, the final grade corresponds to the grade obtained in this exam.
Improvement of the final classification distributed
The student can improve his final grade obtained by continuous evaluation by taking the exam.
Attendance system
Continuous assessment includes 2 tests with a weighting of 50%, each, in the final grade. Access to continuous assessment requires the attendance of at least 85% of classes until the first test and another 85% between the 1st and 2nd tests.
