Tesa Brown Sharpe 14.83027 Dial Drop Indicator

Product Description

The TESA BROWN SHARPE 14.83027 is a dial drop indicator designed for precise linear measurement in machining, metrology, and inspection work. It provides a 2-inch measurement range with a resolution of 0.001 inches per graduation, giving technicians and machinists the accuracy needed for setup, runout checks, and surface comparisons. The large 3-inch black dial face displays readings on a 0-100 scale, and a built-in revolution counter tracks cumulative travel. The vertical lug back allows secure mounting to indicator holders, magnetic bases, and transfer stands common in shop and lab environments.

This indicator suits precision measurement tasks in manufacturing, toolroom, and quality-control applications. It is calibrated in English units and advances 0.1 inches per spindle revolution, which simplifies reading multiple-revolution measurements. Machinists, metrologists, and CMM technicians use this type of instrument for part alignment, fixture verification, and machine tool calibration. Its analogue dial format provides immediate visual feedback without batteries or electronics.

Key Features

• 2-inch total measurement range for extended travel applications
• 0.001-inch dial graduation for high-resolution linear readings
• 3-inch diameter black dial face with 0-100 scale for easy readability
• 0.1 inches of travel per spindle revolution for straightforward multi-revolution tracking
• Built-in revolution counter to track cumulative spindle travel
• Vertical lug back for compatibility with standard indicator holders and mounting arms

Compatibility

Designed as an OEM-style drop indicator compatible with standard indicator holders, magnetic bases, and transfer stands that accept a vertical lug back mount.

Installation Notes

Installation and mounting should be performed by a qualified machinist or metrologist familiar with indicator setups. Secure the vertical lug back firmly in the holder before zeroing the dial to prevent shift during measurement. Avoid side-loading the spindle during contact, as this can affect accuracy and cause premature wear. Calibrate against a known reference standard before critical measurements.
