Lever-Type Dial Test Indicators Probe Many Applications

Mitutoyo America Corp.’s lever-type dial test indicators have increased durability, sensitivity and readability. An array of styli and ruby tips allows for probing of many applications and stylus length is marked on the dial face to assist customers when ordering replacement styli, the company says.

A glare-free, flat crystal face has also been incorporated to allow for viewing of graduations. In addition, the font and dial face color were changed. Multiple layers of hard, smudge-resistant coatings on the crystal prevent scratches and contamination, the company says.

According to the company, an O-ring seal on the bezel provides smooth rotation and prevents oil and dust from contaminating the dial face. A flange was added to prevent the bezel from becoming detached during use. Optional limit hands can be attached to the bezel.

Impact-resistance and a one-piece internal assembly provide protection. The one-piece assembly also facilitates replacement of internal components. A sub-plate structure has been incorporated into all models to prevent the stylus from becoming loose. Redesigned mounting of the gears allows the indicators to maintain trackability even with prolonged use, the company says.

There’s also a variety of dial positions including horizontal, horizontal with a 20-degree tilted face, vertical and parallel.
