Answer :
To solve this question about the type of dial indicator face, let's break it down:
1. Understanding the dial numbers:
- The dial has numbers that increase in the clockwise direction as +1, +2, +3, +4.
- In the counterclockwise direction, the numbers decrease as -1, -2, -3, -4.
2. Analyzing the dial arrangement:
- The numbers being both positive in one direction and negative in the opposite direction, centered around zero, suggest that it is balanced around the midpoint (zero).
3. Recognizing the type of dial:
- In dial indicators, a "balanced dial" is typically designed to have its zero point at the center, with numbers increasing in both positive and negative directions symmetrically. This design is helpful in measuring deviations from a central value, making it useful for various precise measurement tasks where the midpoint is crucial.
4. Conclusion:
- Based on the description given, the dial indicator face is a "balanced dial."
Therefore, the type of dial indicator face described is a balanced dial, which corresponds to option d.
