Tesa Brown Sharpe 01889023 Dial Test Indicator 0.030 in

Product Description

The TESA BROWN SHARPE 01889023 is a horizontal-style dial test indicator designed for precision measurement work in machining, inspection, and metrology applications. It reads to a maximum of 0.030 inches with a 0-15-0 balanced dial graduation, allowing the technician to detect deviation in either direction from zero without reversing the indicator. The dial face is 1.5 inches in diameter with a black dial for clear contrast. A single contact point is included, with an 18.00 mm (0.700 inch) contact point length and a 2.00 mm (0.080 inch) ball diameter at the tip.

This indicator is suited for use on surface plates, magnetic bases, transfer setups, and machine tool fixtures in both production and inspection environments. The horizontal lever-style design allows the contact point to approach the workpiece from the side, making it well-suited for bore measurement, runout checks, and setups where a plunger-type indicator cannot be oriented correctly. Machinists, tool and die makers, and quality control technicians are the primary users of this instrument.

Key Features

• 0.030 inch maximum measurement range with 0-15-0 balanced dial reading
• Horizontal indicator style for side-approach contact and bore or runout inspection
• 1.5 inch diameter black dial for high-contrast readability
• Includes one contact point: 18.00 mm length with 2.00 mm ball diameter
• Compact and lightweight at 0.25 pounds for easy fixture and arm mounting

Compatibility

Designed as an OEM-style dial test indicator compatible with standard dovetail-mount indicator holders, universal magnetic base arms, and indicator transfer fixtures accepting a horizontal lever-style indicator body.

Installation Notes

Dial test indicators are typically mounted and adjusted by machinists or metrology technicians using a magnetic base, articulating arm, or dedicated indicator holder. Secure the mounting stem firmly before zeroing the dial to prevent drift during measurement. Avoid side-loading the contact point beyond the instrument's designed measuring arc, as this can cause wear or damage to the internal lever mechanism. Handle the contact tip carefully during installation and removal to protect the precision ball tip.
