Test: Transducers- 2 - Question 3
Save

Which of the following can be measured using change in resistivity?

Detailed Solution for Test: Transducers- 2 - Question 3
Change in resistivity can be brought in the measurement of all the mentioned quantities, as resistivity is sensitive to temperature.
Test: Transducers- 2 - Question 4
Save

What will happen for resistivity metal and semiconductor if the temperature is increased?
Detailed Solution for Test: Transducers- 2 - Question 4
Metal has a positive temperature coefficient of resistance and semiconductor has a negative temperature coefficient of resistance.
Test: Transducers- 2 - Question 5
Save

What is the relation of the temperature coefficient of resistivity on the coefficient of thermal expansion in RTD?
Detailed Solution for Test: Transducers- 2 - Question 5
It is used to provide a considerable change in resistance when exposed to temperature.
Test: Transducers- 2 - Question 6
Save

A metal with a temperature coefficient of resistance has a value of 200; its initial resistance is given by 40Ω. What will be the final resistance value for an increase in 300C to 350C?
Detailed Solution for Test: Transducers- 2 - Question 6
Answer obtained using expression RT=R0(1+αΔT), where α represents temperature coefficient of resistance, R0 and RT represent initial and final resistance values.
Test: Transducers- 2 - Question 7
Save

Which of the following can be used to measure using thermistors?
Detailed Solution for Test: Transducers- 2 - Question 7
Thermistor at 200C can be used to measure resistance values between 100Ω and 1MΩ.
Test: Transducers- 2 - Question 8
Save

Thermistors may be in wire form.
Detailed Solution for Test: Transducers- 2 - Question 8
Due to high brittleness, thermistors cannot be formed into wire types. Hence they are shaped into bead form.
Test: Transducers- 2 - Question 9
Save

Which of the following is correct for thermistors?
Detailed Solution for Test: Transducers- 2 - Question 9
For thermistors, as temperature increases, resistance decreases.
Test: Transducers- 2 - Question 10
Save

Thermistors have high stability.
Detailed Solution for Test: Transducers- 2 - Question 10
The stability of thermistors is not satisfactory. They can be improved by using high temperatures.
Test: Transducers- 2 - Question 11
Save

Capacitive transducers can be used by _______________
Detailed Solution for Test: Transducers- 2 - Question 11
Capacitance of a material is affected by the area and distance of separation of plates and dielectric material.
Test: Transducers- 2 - Question 12
Save

Capacitive transducers cannot be used as strain gauges.
Detailed Solution for Test: Transducers- 2 - Question 12
Strain to be measured is applied to parallel plates of a capacitor, and total displacement change will be proportional to strain.
Test: Transducers- 2 - Question 13
Save

Which of the following is correct for the capacitive transducer?
Detailed Solution for Test: Transducers- 2 - Question 13
Capacitive transducers find application in measuring both strain, pressure, and angular displacement. Hence all of the mentioned can be treated as applications of capacitive transducers.
Test: Transducers- 2 - Question 14
Save

For a material capacitance increases with _____________
Detailed Solution for Test: Transducers- 2 - Question 14
Capacitance can be represented as C=ε0εrA / d

Where,

εr represents dielectric constant

A is the area of the plate

d is the distance between plates.

Test: Transducers- 2 - Question 15
Save

Which of the following is correct for moisture transducers?
Detailed Solution for Test: Transducers- 2 - Question 15
Dielectric constant of pure water is 80, which is much greater than other materials; this characteristic helps in measuring moisture content.
Test: Transducers- 2 - Question 16
Save

Which of the following devices is used for measuring relative humidity?
Detailed Solution for Test: Transducers- 2 - Question 16
Hygrometers are special devices applicable for measuring the relative humidity of a medium.
Test: Transducers- 2 - Question 17
Save

Which of the following quantities cannot be measured by capacitive transducers?
Detailed Solution for Test: Transducers- 2 - Question 17
Capacitive transducer finds application in measuring almost all quantities like displacement, thickness, moisture speed, etc.
Test: Transducers- 2 - Question 18
Save

Which of the following have high relative permittivity?
Detailed Solution for Test: Transducers- 2 - Question 18
Dielectric constant or relative permittivity of Bakelite is about 4.4; for marble, it varies from 8 to 10, and for paraffin, it is only 2.2.
Test: Transducers- 2 - Question 19
Save
