What the AI looks for in Electronic Indicators
- Absolute vs incremental
- Prefer an absolute encoder. An absolute encoder keeps its zero and position after power-off and does not lose count if the plunger moves too fast.
- Resolution vs accuracy
- Check the stated accuracy, not just the displayed resolution. The last displayed digit is often finer than the instrument's real accuracy.
- Coolant protection
- Use an IP-rated model near coolant or chips. Unsealed units fail when coolant gets inside.
- Data output
- Needed only for SPC or logging, and check that the output protocol matches your collection system. Output protocols are proprietary between brands.
- Stem standard
- 3/8 in or 8 mm stem matching your holders. The wrong stem size means it will not fit your existing stands.
Brands that matter
- Mitutoyo: The Digimatic line sets the benchmark.
- Starrett: Offers electronic indicators.
- iGaging: Budget digital option.
- Sylvac: Swiss high-end digital indicators.
What to avoid
- Incremental-only units for setups where the indicator gets bumped or switched off
- Unsealed units used in flood-coolant machines
