Spring 2010 CEE 291 – Problem Solving Using Computer Tools Homework 5: Measurement methods and analysis (may be done in either Excel or Matlab) Assigned: 3/1/2010 Due: 3/8/2010 by 5:00 pm in the ECOW2 drop box and in the hall box outside 1261 EH. Problem 1 Consider a manufacturer’s specifications in the Table on a pressure transducer. Pressure Transducer Specifications Operation Performance Input range 0 – 1000 cm water Linearity error ± 0.5% FSOR Excitation ± 15 volts DC Hysteresis error < ± 0.15% FSOR Output range 0 – 5 volts Sensitivity error ± 0.25% of reading Thermal sensitivity error ± 0.02%/ 0 C of reading Thermal zero drift 0.02%/ 0 C FSOR Temperature range 0 – 50 0 C with FSOR = full-scale operating range (for pressure, FSOR = 1000 – 0 =1000 cm) If this transducer is selected to measure a nominal pressure of 500 cm of water, and the ambient temperature is expected to vary between 18 0 C and 25 0 C, determine the: a) magnitude of each elemental error affecting the measured pressure; and
