engineering recuitment GATE IN Test Series 2023-24 Mock Test Sensors and Industrial Instrumentation Capacitive Transducers
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
1
619 pF
2
447 pF
3
325 pF
4
275 pF
