Pressure Sensor Quiz

What is a major limitation of Bourdon tube sensors?

• Inability to measure high pressure

• Sensitivity to shock and vibration

• High cost of maintenance

• Requirement for secondary elements

Bellows-type sensors are primarily used for which pressure range?

• High pressure

• Medium pressure

• Extra low pressure

• Low differential pressure

In a strain gauge sensor, what happens to resistance when the gauge is compressed?

• It increases

• It decreases

• It remains constant

• It fluctuates

Which sensor type is best suited for dynamic pressure measurements?

• Bourdon tube sensor

• Bellows-type sensor

• Strain gauge sensor

• Piezoelectric pressure sensor

Piezoelectric pressure sensors are unsuitable for measuring:

• Static pressure

• Dynamic pressure

• Low-frequency pressure changes

• High-frequency pressure changes

The primary function of a Bourdon tube sensor is to:

• Convert pressure changes into electrical signals

• Directly indicate the pressure of fluids

• Measure differential pressure in low ranges

• Convert fluid flow into pressure

Which of the following materials is commonly used to construct Bourdon tubes?

• Quartz crystal

• Copper alloy

• Phosphor bronze

• Stainless steel

In a Wheatstone bridge circuit, the strain gauge sensor operates by:

• Generating an electric charge due to crystal strain

• Changing resistance in response to mechanical force

• Creating a signal through liquid displacement

• Directly measuring differential pressure

A piezoelectric pressure sensor is most effective in applications where:

• Static pressure measurements are needed

• The sensor must measure rapid, dynamic pressure changes

• Differential pressure in the low range is measured

• The pressure measurement must be remote

The purpose of using a displacement sensor in conjunction with a Bourdon tube sensor is to:

• Improve sensitivity to dynamic pressure changes

• Measure low-pressure differential readings

• Convert mechanical displacement to an electrical signal

• Stabilize the pressure reading in high-vibration environments
