Question: The capacitance C₁, of a diaphragm pressure sensor increases as the measured pressure increases. The shown deflection-type AC Bridge is used to indicate the change in C₁, as a change in V. The component values are Vin 24 Vrms; R₂ 145 ; R₁-15 2; C₁-3 mF. The resistance of the measuring voltmeter is neglected. Answer the following: = A. What is the output voltage when the diaphragm capacitance is C₁ = 0.1mF B. What is the output voltage when the diaphragm capacitance is C₁ = 1.2mF C. Assuming that the diaphragm capacitance varies linearly with the measured pressure from 0 to 9 bar, where Cu changes from 0.1 mF to 1.2 mF. what is the measurement sensitivity in Vms/bar Vin 3 C1 Vout R3 www m R2
