ENVIRONMENTAL INSTRUMENTATION
Lectures, Laboratories
Instructor: Dr. J.D. Wilson
Class Homepage: http://courses.eas.ualberta.ca/eas327/index.html
Calendar Description: Laboratory work and lectures to develop skill in environmental measurement through comprehension of first principles. Instrumentation (basic electronics; matching signal sources and receivers; noise; frequency response). Sensor-environment coupling (heat and mass transfer). Sampling theory. Principles will be applied to selected environmental monitoring instruments. Pre-requisites: EAS 102 and Math 113 ("Elementary Calculus 1").

Textbook: "Web Notes" at http://courses.eas.ualberta.ca/eas327/index.html
Lectures (40%): Tuesdays and Thursdays, 1230 - 1350, in Tory 2-117.
Laboratories (60%): Generally Tuesday 1400 - 1550, though some flexibility will be needed as one or more labs may take place elsewhere on campus, possibly in Mechanical Engineering... and there is a timetabling clash with the lab for EAS 471. The class will be split into two groups, and each lab will be run at least twice, on consectutive Tuesdays.

Option: You may team up with up to two other students to submit a single report (same mark assigned for each member of the pair). You may opt out of this (and submit an individual lab report) at any time.
Criteria in marking lab reports: Tidy and legible? Well organized (Introduction, Conclusion, Headings, etc.)? Coherent, and written in clear, unambiguous English? Numbers given with an appropriate number of significant figures and with correct units? Informative use of figures? Diagrams/graphs tidy? Axes labeled and titles given? Clear demarcation of experimental and theoretical curves/points? Suitable choice of axes? Does report (concisely - without unnecessary detail, such as repetition of the instructor's handout) demonstrate that the student has understood the concepts and procedures involved in the lab, without factual or conceptual errors? With any special insight? Please see On Writing Lab Reports for some further hints.
Scope of Laboratories:
Basic electronics (floating versus grounded devices; voltage divider or "half bridge"; internal resistance of a source; Wheatstone ("Full") bridge; RC lowpass filter). Recording and datalogging. Heat Transfer (measure the Nusselt number of a cylinder in an airstream). Calibration of temperature and/or humidity and/or pressure sensors.
