Abstract
A piezoelectric crystal based detector/controller for monitoring the l evel of sulfur dioxide in the environment is described. In this instan ce, the device is configured as a detector/monitor giving an alarm rat her than a control function. Additionally, a transmitter was added to allow remote monitoring. Coatings studied included ethylenedinitrilote traethanol, triethanolamine and quadrol. Good results were obtained at ambient and higher than ambient temperatures.
