20 copyright (c) 2011 Stefan Rudbäck, Matematica, , matematica.se sid 20 With Matematica double precision non stop technology the following is possible; -The measurement uncertainty can be reduced to a limit defined by the user (to a certain limit). -The reliability can be improved to a limit defined by the user. (transmitter failure will be non-stop handled by the system) -Transmitters can be simplified. It’s often better with multiple simple (cheap) transmitters than 1 advanced (expensive). Failures will be non-stop handled. -Safety system operating parallell with the production system can be eliminated. Failures will be non-stop handled. -Real transmitter errors will be calculated.
