Multi-Sensor CMMs
Most parts carry both features suited to tactile probing — bores, planes, threads — and features only optics can reach: thin-wall edges, micro-geometry, compliant surfaces. A multi-sensor machine places tactile, vision and laser sensors in a single coordinate system so every feature is captured in one setup. That removes transfer and realignment between machines, and with it the datum mismatch that otherwise creeps into the result.

What is a multi-sensor measuring machine?
A multi-sensor measuring machine combines several probing technologies on one machine, under one coordinate system. A tactile probe establishes datums and geometric tolerances; optical or laser sensors handle thin-walled, soft, very thin and free-form features. Everything is captured in a single setup.
The Quantus range uses a rigid fixed-bridge structure with twin Z axes, so two sensors can be carried at once and swapped without re-clamping or re-aligning the part. That is the real advantage over owning two separate machines.
When does multi-sensor beat separate machines?
The test is simple: if a part has to move between two machines to be fully inspected, setup error enters the result — and that error is usually larger than either machine's stated maximum permissible error.
Complex assemblies, metrology laboratories and first-article inspection in advanced manufacturing are where multi-sensor pays for itself. For high-volume checks of one simple feature, a conventional CMM remains the better economics.
How do Quantus, Quantus-B and Quantus-W differ?
Quantus covers measuring volumes from 500×500×300 mm to 1000×1200×500 mm, with maximum permissible error from 0.9+L/300 µm. Quantus-B extends the same multi-sensor principle to larger housings and structural parts. Quantus-W adds temperature and geometric error correction modules for measurement in shop-floor conditions.
Choose by envelope first, then work back from the tightest tolerance on the drawing to the accuracy class you need, and only then decide which combination of sensors the part actually requires.
