| Monday, October 16, 2006 1:30 p.m. to 5:30 p.m. Fundamentals of Transducers and Instrumentation
for the Precision Engineer Design of precision systems requires knowledge of transducer operation, limitations and signal handling/processing. For compatibility with information and control systems, precision measurements are required in electronic or opto-electronic format. The tutorial will overview transducers by their operating principles which permits a progressive developmental approach. Relationships between physical/mechanical parameters and electrical/electronic, optical (fiber) and opto-electronic phenomena will be developed and merits and shortcomings reviewed. For many applications in electro-mechanical environments, noise is a significant issue. For low noise susceptibility, different modulation techniques will be considered with appropriate signal handling and processing. Choices will be considered between original base-band measurements, modulated systems and coherent signal recovery techniques (e.g. ‘lock-in’ and ‘box-car’) for improving noise performance. Applications’ will be analyzed using examples taken from measuring instrument improvement and machine performance testing. The tutorial is suitable for the precision mechanical engineer needing measurement/control automation insights.
