Instrumentation Transducers Notes



Instrumentation Transducers Questions and Answers now we will see  Temperature Measurement notes, force measurement notes, pressure measurement.

1. Output of a bimetallic element will be

Displacement

So remember Bimetallic element is used for measuring temperature, it produces proportional output displacement for input temperature.

2. Fluid expansion system can be used for measuring temperature.

3. IPTS stands for International Practical Temperature Scale.

4. In liquid in steel bulb thermometer, Mercury liquid can be used for measuring temperature up to 60000C.

Mercury as a liquid provides temperature range of -4000C to 65000C.

5. Bourdon tube is used as indication instrument in liquid expansion system.

Bourdon tube converts pressure into displacement and in liquid expansion systems output expansion pressure is applied to bourdon tube for indication purpose.

6. Which of the following is true for bimetallic type thermometer?

Two metals have different temperature coefficient
In a bimetallic type thermometer, two metals are used which are different in temperature coefficients.
7. Analogous quantities of heat flow and temperature in electrical are Current and potential.

8. Ratio of net amount of heat received and stored in the body for certain time interval is known as Thermal storage capacity.

Here today willl discusd on Instrumentation Transducers notes on Force Measurement.
This notes of Instrumentation Transducers on
” Force Measurement”.

9. Beams is the  device can be used for force measurement.

And remember Bellows, Capsule, Bourdon tube are used for measuring pressure.

10. Load cells are used for measuring Slowly moving weights

so that their weight will be uniformly distributed over load cell surface.

11. Small weight can be measured using Ring-type load cell.

12. Both tensile and compressive strain gauges arrangements are used in load cells.

13.  following conversion is correct for load cell....

Both force to strain and force to displacement

14. Diaphragm element can also be used for force measurement.

15.Force is a vector quantity

16 diaphragms Used for measuring small forces

17 Load cells are primary
transducers.

This set of notes on Instrumentation Transducers discuss about  on “Pressure Measurement”.

18. Pressure difference between manometric and measuring liquid detected using
manometer device.
19. Primary transducer be thin plate diaphragm included.

20. Which of the following quantities can be measured using bellows?

a) Absolute pressure
b) Gauge pressure
c) Differential pressure
Answer is  all of the mentioned.

21. Pressure to displacement conversion take place in bourdon tubes.
