Self-Validating Sensors: towards Standards and Products

For the last ten years, Oxford University and the Foxboro Company have been developing the concept of the Self-Validating (Seva) sensor. Accordingly over the last year there have been a number of developments leading to a British Standard for on-line measurement quality assessment based upon Seva. This paper will cover each of these topics in turn . Firstly, the fundamentals of Seva will be described. The recent standardisation activities will then be discussed, followed by the moves towards commercialization. Finally, some recent research results from Oxford will be presented.
