The difference between mechanical Comparator and electrical Comparator is as follows:
MECHANICAL COMPARATOR:
- The Mechanical Comparator has more number of moving parts.
- Due to more moving parts present in this system there is a high rate of wear and friction.
- Mechanical comparator is not high accuracy.
- Readings of this Comparator do not affect by variations in power supply.
- This can be maintained easily.
- This type of comparator is less cost.
- This type of Comparator does not depend on the external supply of current.
- Due to the more number of moving parts present in the comparator it is sensitive.
- Magnification range is comparatively low than electrical type .
ELECTRICAL COMPARATOR:
- The Electrical Comparator has less number of movable parts.
- Due to less moving parts there is a less in wear and friction.
- Electrical comparator is high in Accuracy.
- External supply of current is needed.
- In this, the instrument is affected by the fluctuation in the frequency of an external power supply.
- This type of Comparator is more costly.
- Due to less number of movable parts, this is not sensitive to vibrations.
- Magnification range is higher than mechanical type.
