Question

Dial gauge typically measure in the range of _____.
1. 600 mm to 700 mm
2. 400 to 500 mm
3. 800 to 900 mm
4. 0.25 to 300 mm

Answer 1

Correct Answer - Option 4 : 0.25 to 300 mm

Explanation:

• Dial indicators are simple mechanical devices that convert linear displacements of a pointer to rotation of an indicator on a circular dial.
• The indicator is set to zero at a certain reference surface, and the instrument or the surface to be measured is brought into contact with the pointer.
• The movement of the indicator is read directly on the circular dial.
• The typical least count that can be obtained with dial indicators is 0.01 mm.
• It measures the measurement in the range of 0.25 to 300 mm.
• It is possible to use the dial indicator as a comparator by mounting it on a stand at any suitable height.
