A capacitance transducer uses two quartz diaphragms of area 750 mm² separated by a distance 3.5 mm. The capacitance is 370 pF. When a pressure of 900 kN/m² is applied, the deflection is 0.6 mm. The capacitance at this pressure would be:

A. 1 B. 0.84 C. 0.73 D. 0.65

A. Should be nonmagnetic B. Most be of low temperature coefficient C. Should have low specific resistance D. All of the above

A. The meter is calibrated for AC and it’s error for DC would be high B. The meter does not respond to DC signals C. The error is high due to hysteresis effect D. The error is high due to eddy current effect

A. A shunt resistance B. A series inductance C. Shunt capacitance D. Series resistance
