Sensors Quiz

Which of the following is NOT a fundamental quantity in measurement?

• Length

• Mass

• Time

• Force

The process of determining the value of a measured quantity is known as:

• Measurement

• Calibration

• Transduction

• Error analysis

Which of the following types of errors is caused due to faulty equipment?

• Random error

• Systematic error

• Gross error

• Measurement error

In error analysis, the term “precision” refers to:

• The closeness of measured values to the true value

• The consistency of repeated measurements

• The difference between the true value and measured value

• The average of repeated measurements

Which of the following refers to the ability of a transducer to respond to a change in the measured quantity?

• Sensitivity

• Linearity

• Hysteresis

• Time constant

Which of the following is a dynamic characteristic of a transducer?

• Repeatability

• Accuracy

• Sensitivity

• Response Time

The term "sensitivity" of a sensor is defined as:

• The capacity of the sensor to withstand external forces

• The time required for the sensor to respond

• The ratio of the noise to the signal

• The ratio of the output signal to the input signal

The accuracy of a sensor is determined by:

• The time delay in the response of the sensor

• The range of the sensor

• The deviation of the output from the true value

• The precision of the sensor

Which type of sensor is used for measuring temperature?

• Capacitive sensor

• Piezoelectric sensor

• Thermistor

• Strain gauge

Which of the following is an example of a digital output from a sensor?

• Binary code output

• Frequency signal
