Embodiment Construction

[0026] For any chemical detection system to perform satisfactorily, a number of design techniques must be utilized. For example, a system designed to provide a chemical sensor as well as a chemical sample of interest must be fully operational before starting the measurement environment. Furthermore, chemical sensors must be designed to withstand the contaminating elements in the operating environment. The present invention teaches those of ordinary skill in the art not only how to make the system work effectively, but also how to confirm the health and integrity of the chemical sensors themselves.

[0027] In order to fully appreciate the advantages of the present invention, it is necessary to understand the system components and how they work to detect chemicals. Although the preferred embodiment teaches diagnostic techniques with respect to control valves, one of ordinary skill in the art will recognize that the same applies to other process equipment, such as pumps. GO TO...

Abstract

A chemical detection system performs controlled exposures to diagnose the pneumatic components and chemical sensors prior to measuring a chemical emission. A control module provides the system control and data processing to perform the diagnosis. The control module manipulates an emission sample retrieval system to provide precise exposure during the diagnostic routines. A sensor interface circuit interrogates the chemical sensors and stores the data for analysis. The chemical sensor exhibits predictable changes in response during predetermined exposure scenarios. By utilizing numerous time domain signal processing techniques, both system and sensor level fault conditions are determined.

Description

[0001] This application is related to U.S. Patent No. 6,222,366, filed May 10, 1999, entitled "High Frequency Measuring Circuit with Inherent Noise Reduction for Resonating Chemical Sensors," and U.S. Patent No. 6,029,506, filed November 12, 1997, entitled "Sample Retrieval System," and U.S. Patent No. 5,451,923, filed September 2, 1994, entitled "Communication System and method," and assigned to the assignee of this patent application, and incorporated herein for reference. technical field [0002] The present invention relates to an apparatus and method for diagnosing a chemical detection system used to quantify volatile organic emissions from equipment used in process industries. Background technique [0003] Plants dealing with volatile organic compounds (VOCs) typically experience the emission of those harmful compounds into the atmosphere from point sources such as chimneys and non-point sources such as valves, pumps and VOC-containing containers. Emissions from non-p...
