Question

_____________ measure dynamic pressure.

(a) Bourdon tube pressure gauges

(b) Barometric sensor

(c) Piezoelectric pressure sensor

(d) Piezoresistive pressure sensor

This question was posed to me in a job interview.

The doubt is from Pressure Measurement in a Fluid in chapter Fluid Flow Theory & Applications of Food Processing Unit Operations

Answer 1

Right option is (c) Piezoelectric pressure sensor

For explanation I would say: Piezoelectric pressure sensors measure dynamic pressure. The dynamic pressure measurements include the blast, ballistics, turbulence and engine combustion. These sensors have the ability to measure quasi static pressures. They are fast response, extended ranges, ruggedness and high stiffness
