Dial Thickness Gauge

Measurement Precision & Tolerances

The Dial Thickness Gauge provides a mechanical dial indicator coupled to a precision spindle and anvil for direct thickness measurement. Typical resolution is indicated on the dial in 0.01 mm or 0.001 in subdivisions depending on the model family. The instrument is intended for quick go/no-go checks and small-batch dimensional verification where bench micrometers are impractical.

Calibration & Compliance

Calibration is performed against traceable gauge blocks and documented in a CMM lab for dimensional validation. The gauge supports periodic recalibration and adjustment to maintain repeatability. Use a certified calibration block during first installation and schedule routine recalibration per the quality plan.

Processing Insight & Technical Notes

For thin flexible substrates, support the workpiece on a flat backing to avoid sagging during measurement. For hard metallic parts, ensure contact faces are clean and free of burrs to avoid false readings. The dial mechanism is best protected from coolant spray and heavy contamination; use protective boots if used near machining centers.

Applications & Use Cases

• Incoming Inspection: QC teams verifying supplier sheet thickness to contract tolerance before assembly.
• Process Control: Production operators performing in-line spot checks on stamping and lamination stations.
• Maintenance & Repair: Workshop teams validating gasket or shim thickness during service.
