REMOVING OLD SENSOR MYSTERY WITH IEEE P1451.3 AND .4 STANDARDS

Abstract

When a sensor is replaced or added to a legacy data acquisition system, information for that sensor has to be incorporated by the software programmer into the main system software - a costly and timeconsuming process. The new ‘smart’ sensors that are being designed according to the new IEEE P1451.3 and .4 standards will have the necessary information contained in their Transducer Electronics Data Sheet (TEDS). A method has been developed to give the old sensors the intelligence to meet the requirements of these new IEEE standards without changes to the legacy hardware and a minor change to the system software.
