Use the DAS of Example 7.13 for a pressure transducer with the following specifications: Range 0 to 2000 kPa Output 0 to S V Linearity and hysteresis (combined) 0.2S% FS Repeatability Thermal span uncertainty O.03% FS O.003%FS/OC The temperature is uncertain to 100C. Select the DAS input range that gives the best accuracy. Estimate the uncertainty of a pressure measurement made with this system.
ENGR 121 B Lab Notes for 9/28/2016 Spencer Kociba ● vec=a:b:c ○ a=min/starting number ○ b=increment ○ c=max number ● logspace(X1, X2, N) ○ X1=starting point is 10^X1 ○ X2= ending point is 10^X2 ○ N= number of elements created ● x=([a:b], c) ○ a=start ○ b=end ○ c=the last element of the vector ○ Ex. mat=([5:1:3]; 1:3; 44, 9, 2) ■ >>> ● numel(matrix name) ○ Counts number of elements in the specified matrix/vector ● x=mat(3:)
