MDS-PCD Intelligent digital dial indicator

The MDS-PCD series is a five-button digital indicator featuring an aviation aluminum body and a glass capacitive sensor, delivering rugged construction and stable readings. Equipped with a large digital display, it supports both absolute and relative measurement modes. Users can preset actual position values and define upper and lower tolerance limits; the system automatically determines deviation status for quick pass/fail judgment. The built-in high-speed data acquisition function automatically captures and stores maximum and minimum values, making it particularly suitable for runout measurement. One‑key conversion between metric and imperial units is supported, while a Micro data output interface enables connection to external devices for streamlined data management. Powered by a high‑capacity 3V lithium battery, the unit features both automatic and manual shutdown for extended battery life. In terms of performance, the measuring range covers 12.7 mm to 50.8 mm, with a resolution of 0.005 mm / 0.0002 in and an accuracy of 20 μm. The IP54 protection rating ensures reliable operation in demanding environments such as precision machining and quality inspection. With its compact design and intuitive five‑button interface, the MDS-PCD series is an ideal measuring tool for both industrial shop floors and laboratories.

Applications

1. Precision Machining:

Machine tool setup, workpiece alignment, and runout measurement (spindle radial/axial runout) to ensure machining accuracy.

2. Quality Inspection:

Incoming/outgoing inspection, in-line pass/fail sorting using preset tolerance limits, and fixture‑based measurements for mass production.

3. Geometric Tolerance Measurement:

Checking roundness, circular runout, total runout, flatness, straightness, and coaxiality of shafts, guides, and assembled components.

4. Equipment Maintenance & Assembly:

Restoring machine tool geometry (parallelism, perpendicularity) during overhaul, and controlling clearances or preload in high‑precision assemblies.

5. Laboratories & Education:

Material testing (measuring small deformations), metrology calibration, and teaching fundamental measurement techniques.
