Motorised probe 8 N for 502.230 / 502.231 / 502.240 / 502.241 — motorised ultrasonic probe, 8 N measuring force (M502.263)

Motorised probe 8 N for 502.230/502.231/502.240/502.241 is a drive‑assisted ultrasonic probe designed for repeatable surface roughness inspection in laboratory and production environments

• Motorised drive for consistent contact force
• 8 N measuring force for stable readings
• Probe tip Ø36 mm with low surface roughness Ra < 2 μm
• Compact dimensions 197.5 x Ø46 mm for tight setups

Repeatable roughness measurement with motorised contact

The probe's motorised drive ensures a constant 8 N measuring force, eliminating a major source of variability in tactile roughness inspection. This reproducible contact pressure translates into more reliable series measurements and reduces rework caused by operator variation. The design is optimised for use with surface roughness metres and provides a stable measurement interface for comparative quality control and process monitoring.

Mechanical design that supports precision and stability

Engineered with a compact envelope of 197.5 x Ø46 mm and a mass of 1 kg, the probe combines manoeuvrability with sufficient inertia to remain stable during measurement cycles. The Ø36 mm probe tip and Ø3.7 mm oscillation rod deliver a controlled contact geometry; the probe face is finished to Ra < 2 μm to avoid introducing artefacts. These mechanical choices reduce bending and vibration at the contact point, which benefits repeatability in both laboratory and production contexts.

Integration and application range for practical workflows

The unit is compatible with roughness analysers of the 502.230, 502.231, 502.240 and 502.241 series and is intended for test pieces with a minimum thickness of 2 mm and a minimum mass of 0.3 kg, making it suitable for small components and assemblies. The probe is particularly well suited to quality inspection stations and inline measurement rigs where a compact, motor‑assisted transducer simplifies handling and shortens cycle times.

Operational reliability and measurement clarity

With a focus on stable measurement conditions, the probe's motorised actuation reduces operator influence and supports automated test sequences. The construction and surface finish minimise measurement disturbance while the overall form factor allows straightforward mounting and alignment in test fixtures. Where traceable, repeatable roughness data are required, this probe supports consistent results across batches and shifts.
