Manual Probe 20 N for 502.230 / 502.231 / 502.240 / 502.241 — Ultrasonic Probe with Manual Drive (Metav IndustryLine)

The Manual Probe 20 N is a manual ultrasonic probe designed to provide consistent contact pressure for surface roughness measurement on compatible roughness testers.

• Manual drive for controlled contact
• 20 N constant measurement force
• Ø5.5 mm measurement tip
• Suitable for Ra < 5 μm measurements

Repeatable contact force for dependable results

A constant 20 N measuring force ensures that contact pressure variance is minimised, which directly improves repeatability in surface roughness readings. The probe’s manual actuation delivers tactile control while the compact design keeps inertia low; this combination reduces operator-induced scatter and supports faster throughput in routine checks. With a probe mass of 1 kg and compact external dimensions 154 x Ø22, handling is practical during serial inspections while maintaining the mechanical stability needed for consistent ultrasonic coupling and measurement.

Compact geometry for tight fixtures and small specimens

The slender Ø2.4 mm oscillation rod and the Ø5.5 mm measurement tip were selected to access confined features and small radii without compromising signal transfer. The probe is suitable for test pieces with a minimum thickness of 2 mm and a minimum weight of 0.3 kg, making it appropriate for components that require delicate placement or sit in small clamping systems. The reduced cross section of the probe head simplifies positioning in jigs and fixtures, which accelerates setup and reduces non-productive time in both workshop and quality-control environments.

Clear traceability and surface capability for quality control

The probe is specified for surface roughness levels down to Ra < 5 μm, enabling reliable assessment of fine finishes where control of texture influences function or assembly. Compatibility with roughness testers 502.230 / 502.231 / 502.240 / 502.241 makes integration straightforward, and the robust mechanical configuration supports stable ultrasonic coupling during measurement cycles. The device’s specification prioritises measurement integrity, providing a technically sound basis for process decisions and corrective measures in production monitoring.
