1. A pressure sensor outputs a voltage varying as 100 mV/psi and has a 2.5 kΩ output impedance. Develop signal conditioning to provide 0 to 2.5 V as the pressure varies from 50 to 150 psi.
2. A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 s. The required output is a voltage varying from to +2.5 V for the cycling flow range. The sensor to be used has a transfer function of √Q volts, where Q is in gal/min, and an output impedance of 2.0 kΩ. Tests show that the output of the sensor has 60 Hz noise of 0.8 V rms. Design a signalconditioning system, including noise filtering, and evaluate your design as follows.
a. Plot output voltage versus flow, and comment on the linearity.
b. Determine the noise on the output as percent FS.
