MECHANICAL COMPARATOR
• DIAL INDICATOR• REED TYPE MECHANICAL COMPARATOR
DIAL INDICATORS
The linear movement of the spindle is magnified by gear and pinion into sizable rotation on the dial scale
Converts a linear displacement into a radial movement to measure over a small range of movement for the plunger. Applications include,
- centering workpieces to machine tool spindles- offsetting lathe tail stocks- aligning a vise on a milling machine- checking dimensions

Profile projectorThe object to be tested is
placed on the work table.The light beam after
passing through after passing the object to be projected passes into the projection system comprising lenses and mirrors.
The lenses are used to get the desired magnification and mirrors to direct the beam of light on screen
