An equipment catalog boasts that a pressure transducer system. There are two candidate models to choose from: Model A or Model B. The resolution of Model A is 0.01 kPa while that of Model B is 0.001 kPa. Model B costs substantially more. Both units are otherwise identical. The specifications list the uncertainties for three elemental errors: Linearity error 0.15% FSO
Hysteresis error 0.20% FSO
Sensitivity error 0.25% FSO
For a full-scale output (FSO) of 20 kPa, calculate the design-stage uncertainties for both models. Which model with you select? Explain.
