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 differential capacitive sensor with a distance between the extreme plates 100 mm is shown in figure below. The difference voltage ∆V = V1 − V2, where V1 and V2 are the rms values, for a downward displacement of 10 mm of the intermediate plate from the central position, in volts, is
Assertion (A): Capacitive transducers are, in fact, primary transducers for measurement of displacements.Reason (R): A Capacitive transducer is a non-loading, non-contact and non-invasive type transducer for displacement measurements.
A capacitive transducer consists of two parallel plates of diameter 2 cm each and separated by an air gap of 0.25 mm. What is the displacement sensitivity?
Direction: It consists of two statements, one labeled as ‘Statement (I)’ and the others as ‘Statement (II)’. You are to examine these two statements carefully and select the answer using the codes given below:Statement (I): Force and pressure can be measured by using a capacitive transducer.Statement (II): Capacitive transducer can be used to measure both static and dynamic phenomena.
