Abstract |
This report is a continuation of an investigation to quantify the operating characteristics of vapor sensor technologies used at underground storage tank (UST) sites. During this study, a third vapor sensor technology, the catalytic bead sensor, was selected and tested. The testing was performed using the Carnegie Mellon Research Institute (CMRI) automated gas testing facilities. This automated system monitored the sensors' responses while dynamically exposing them to various mixtures of methane, butane, and xylene. The sensors were also tested to determine the effects of humidity on their responses. Sensor responses were characterized by sensitivity, selectivity, speed of response, and speed of recovery to selected test concentrations of methane, butane, and xylene. The test results are presented as a list of sensor specifications to allow for direct comparative method of collecting and processing sensor data that compare distinct vapor sensor technologies. These projects were not designed to fully characterize the vapor sensors under study. |
