2.3. Select Sensor Types

Try these first

1. 1.

   What does a strain gauge measure?

   Hint

   Think about how materials react to force.

2. 2.

   Name one application of an accelerometer.

   Hint

   Consider situations involving vibrations.

3. 3.

   What is the primary function of a strain gauge?

   • To measure pressure
   • To monitor strain
   • To detect temperature

   Hint

   Think about what it measures relative to force.

4. 4.

   True or False: Accelerometers can only measure static acceleration.

   • True
   • False

   Hint

   Consider whether they are limited to one type of signal.

5. 5.

   A bridge is experiencing unusual vibrations during traffic. Which sensors would you deploy and why?

   Hint

   Think about the specific measurements needed in this situation.

6. 6.

   An environmental construction project requires monitoring soil moisture and pore pressures. Which sensors would you choose and elaborate on their importance?

   Hint

   Reflect on the role each sensor plays in maintaining safety.
