Advantages of Electrical Comparator:
- Vibrations are reduced due to least weight of mechanical.
- It consists of less moving parts.
- By AC supply the friction errors are reduced.
- For measuring units the indicating instrument can be held at remote locations.
Disadvantages of Electrical Comparator:
:
- The accuracy of this Comparator is affected by supplying of variations in AC current.
- Heating of coils may lead to the occurrence of zero drift.
- It is more expensive.
- Pointer moving over a fixed scale reduces the range of Comparator.
USE OF ELECTRICAL COMPARATOR:
- It is used for measuring head.
- It is used indication panel, to prove visual indicators.
- It is used for external gauging, internal gauging, and thickness gauging.
- It is used for measuring flatness measurement.
