This module is designed to give a learner the necessary knowledge and skills to design, specify or implement instrumentation measurement systems. It provides knowledge of PC data acquisition and competence in selection and use of transducers.In Addition it provides an introductory fundamental knowledge of control systems and analysis.
Measurement Circuits
Operational amplifier, inverting, non-inverting, common mode rejection ratio, comparator / summing circuits etc., data sheet specifications, instrumentation amplifiers, comparators. Noise considerations in measurement. Application of their use.
Electronic Measurement & Transducers
Transducers, principle of operation of light, temperature, force and displacement transducers. Flow and level measurements. pressure measurements and pressure transducers. Optical sensors and systems. Signals and noise in measurement systems. Principles of MEMS (Micro Electrical Mechanical Systems) devices. Use of LabView software to control and collate laboratory measurements. I2C and SPI communication to sensors. LDR calibration techniques.
Industrial Control Sensors
Use of commonly used sensors in process control - e.g. Proximity, capacitance, through beam, ultra sonic, limit switches, photoelectric, fiber optic. Relay switch configurations.
ADC/DAC
ADC & DAC design - Flash, Ramp, Single slope, Dual slope, Sucessive approximation ADC. R2R, dinary weighted sum. Practical considerations in thier use. Noise consideration in thier application.
Lectures/tutorials, practical sessions each week in an electronic laboratory using electronics equipment/sensors and self directed learning.
