EEEN30043 - Sensors and Instrumentation
Availability - Course (Compulsory/Elective)
|Satisfactory completion of the second year of one of the degree programmes of which this unit forms part, or some other qualification deemed equivalent by the School|
The programme unit aims to:
Introduce the student to the research methodologies and techniques used in Electrical Energy Conversion Systems. The topic and the project Specification are arranged jointly between the student and his/her project supervisor.
BRIEF DESCRIPTION OF THE UNIT
(1) Introduction: Overview of sensors, overview of instrumentation.
(2) Fundamental Sensor Concepts: Sensor characteristics: transfer function, range and sensitivity, errors and calibration, accuracy and precision, linearity, hysteresis.
(3) Sensors for position, displacement, level and flow, occupancy.
(4) Sensors for velocity, acceleration, force and strain.
(5) Sensors for radiation: sources, detectors, optical circuit components.
(6) Sensors for temperature: reference points, thermoresistive and thermoelectric sensors.
(7) Sensor interfaces: bridge circuits, capacitance-to-voltage and light-to-voltage converters
(8) Sensing electronic circuits: input characteristics, excitation circuits, overview of amplifiers, amplifier noise (mechanisms, noise figure, noise model).
(9) Signal conditioning: instrumentation amplifier, phase-sensitive modulation/demodulation, signal averaging, ratiometric detection.
(10) System architecture and performance: voltage- and current-transmission systems, noise generation mechanisms and characteristics, external noise coupling and suppression.
(12) System design: quantization error, sampling frequency, aliasing frequency, design practice; commercial DAQ products.
