copyright (c) 2010 Stefan Rudbck, Matematica,+46 708387910, [email protected], matematica.se sid 1 Date: 101212 2.2 Matematica.Lib. -Double precision non stop system for non stop measurement and calculation Specify your demands for; Production reliability and Production precision and Matematica will meet those demands (Ex; see below) Slide 2 copyright (c) 2010 Stefan Rudbck, Matematica,+46 708387910, [email protected], matematica.se sid 2 Example; The function block advanced_avg_calc Calculation of one temp from 4 measurements around a pipe. The calculation is done with normal distribution math, it means better accuracy and stability at transmitter failure. T1T2T3T4 T_avg Slide 3 copyright (c) 2010 Stefan Rudbck, Matematica,+46 708387910, [email protected], matematica.se sid 3 T1T2T3 T4 T_avg Failure of transmitter 4 = no problem Slide 4 copyright (c) 2010 Stefan Rudbck, Matematica,+46 708387910, [email protected], matematica.se sid 4 Example; Improvement of a Power/energy calc system with Matematica.Lib function block advanced_avg_calc. Advanced_avg_calc Return temp Advanced_avg_calc Forward temp Advanced_avg_calc Return flow TF1 TF2 TF3 TF4 TR1 TR2 TR3 TR4 q1 q2 q3 q4 Matematica.Lib Power/energy calculation system (see page 6-8 below) Matematica.Lib Power/energy double precision non stop system and more/less transmitters Slide 5 copyright (c) 2010 Stefan Rudbck, Matematica,+46 708387910, [email protected], matematica.se sid 5 With Matematica double precision non stop system the following is possible; -The measurement uncertainty can be reduced to a limit defined by the user. -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. 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.
