Motorised Probe 3 N for 502.230 / 502.231 / 502.240 / 502.241 — Ultrasonic Probe with Motorised Drive (Metav IndustryLine)

The Motorised Probe 3 N for 502.230/502.231/502.240/502.241 is a motorised ultrasonic probe designed to extend roughness measuring systems with precise, repeatable contact and high-resolution surface assessment.

• Motorised drive for repeatable positioning
• Constant measurement force 3 N
• Probe tip Ø36 mm for reliable contact
• Surface precision Ra <1 μm capability

Consistent measurement force for reliable process control

A stable and reproducible contact force is crucial in surface metrology. The probe offers a constant 3 N measurement force, which reduces variation caused by operator pressure and supports tighter production tolerances. Combined with the motorised positioning, this yields repeatable readings that simplify trend analysis and reduce false rejects in quality control. The emphasis on consistent contact translates directly into less rework and more predictable inspection throughput.

Stable contact geometry and robust oscillation for fine surfaces

The probe’s probe tip Ø36 mm and Ø3.7 mm oscillation rod provide a contact geometry that balances surface conformity with mechanical stability. The compact body (approx. 197.5 x Ø46 mm) and 1 kg mass offer manageable handling while maintaining the stiffness necessary for high-resolution measurements. These characteristics support the detection of fine texture features and help maintain a low measurement uncertainty on components that meet the minimum handling requirements (minimum specimen thickness 2 mm and minimum specimen weight 0.3 kg).

Ready for integration into roughness testers and production lines

Designed as an ultrasonic probe for roughness measurement, the module is compatible with the 502-series measuring heads listed in its designation and connects into established inspection chains without major modifications. The device is specified to assess surface finish down to Ra <1 μm, enabling its use where fine surface integrity matters, from functional contact surfaces to cosmetic finishes. Its form factor and motorised actuation enable automated cycles and repeatable sequences in both laboratory and workshop environments.
