SELF DIAGNOSTIC GAS SENSORS FOR SAFETY AND THE ENVIRONMENT

Objective



This proposal aims to demonstrate principles that can be used to improve the performance of inexpensive semiconductor gas sensors for all of the important flammable and toxic gases by using a common approach to sensor self diagnostics.

The self diagnostic technique has been worked out theoretically by one of the Partners, and demonstrated in preliminary experiments using a model material and electrode system. The work extends this innovation to a verifiable bread-board prototype sensor and signal processing system for testing in at least one practically relevant model environment. The verifiable industrial objective is to develop sensors and associated signal processing which will allow more than one year of maintenance free operation and which when in operation will provide information about the validity of the information being obtained, and any trends arising from unforeseen circumstances which might stimulate maintenance actions at a more frequent interval than that which is scheduled for the installation. The project is vertically integrated, but the industrial partners have multi-sectorial exploitation interests. Economically, the project has strong gearing through reduction of process operating and instrumentation maintenance costs, improvement in the functionality of products and by helping to minimise the cost of compliance with environmental and industrial safety legislation.
