Abstract
Official abstract text for this publication.
A method of operating a sensor system including at least one sensor for detecting an analyte gas and a control system includes electronically interrogating the sensor to determine the operational status thereof and upon determining that the operational status is non-conforming based upon one or more predetermined thresholds, the control system initiating an automated calibration of the sensor with the analyte gas or a simulant gas.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a system including at least a first sensor to detect a first gas analyte, the first sensor being positioned within a housing, the housing having at least one inlet, and a control system, the method comprising: testing a state of at least one transport path of the system by creating a driving force in the vicinity of the at least one inlet of the housing other than by application of a calibration gas including the first gas analyte or a simulant gas for the first gas analyte, measuring a non-analytical response of a second, non-analytical sensor to the driving force and adjusting an output of the at least first sensor via the control system at least in part on the basis of the results of testing the state of the at least one transport path. 2. The method of claim 1 comprising measuring the rate of change of response of the second, non-analytical sensor to the driving force and correlating the rate of change of response of the second, non-analytical sensor to a correction factor for sensitivity of the first sensor to the gas analyte. 3. The method of claim 2 wherein a peak in the rate of change of response of the second, non-analytical sensor to the driving force is correlated to a correction factor for sensitivity of the first sensor to the gas analyte. 4. The method of claim 1 wherein the first sensor is an electrochemical sensor.
