Ultra High Amplification Dial Indicators
> From left to right: dial face with bezel, friction free fully jeweled cartridge style movement and case with lapped chrome plated steel spindle and hardened steel stem.
Dorsey's high amplification dial indicators feature a shock proof "following" type jeweled movement, lightweight interior segmented precision gears and a two piece ring case for unparalleled accuracy and repeatability. Chrome plated hardened steel stem is virtually crush proof. All Dorsey ultra high amplification dial indicators utilize lever principle of motion. They do not rely on rack and pinion motion. This eliminates the inherent error between meshing of racks and gears. The illustration shows Dorsey's unique shock proof, high amplification dial indicator movement. Our dial indicators feature this lever principal and an adjustable eccentric cam to achieve unparalleled accuracy and repeatability.
