6.8. Pressure Sensors

Try these first

1. 1.

   What do piezoresistive pressure sensors measure?

   Hint

   Think about the relationship between pressure and electrical resistance.

2. 2.

   Explain a common application of capacitive pressure sensors.

   Hint

   Consider what these sensors do with capacitance changes.

3. 3.

   What principle do piezoresistive pressure sensors operate on?

   • Temperature variation
   • Resistance variation
   • Capacitance variation

   Hint

   Consider what happens to resistance in electric circuits under pressure.

4. 4.

   Capacitive pressure sensors are primarily used for?

   • True
   • False

   Hint

   Think about how these sensors function.

5. 5.

   Consider a dam equipped with piezoresistive sensors. What would happen if these sensors fail to measure accurately during extreme weather conditions?

   Hint

   Think about the relationship between pressure measurement and structural integrity.

6. 6.

   In a soil analysis project, you use capacitive pressure sensors for pore pressure monitoring. Describe the steps you would take if your readings suddenly showed anomalously high pressure.

   Hint

   Ensure that environmental factors are considered in your analysis.
