EAS 327

January-April, 2005

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").

GFC-Mandated Statements:

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.

Evaluation:

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.
