Maintenance-Free NDT: How evoARC Reduces Downtime and Costs

In the field of non-destructive testing (NDT), equipment reliability can make or break an inspection. Downtime, recalibrations, or fragile setups not only stall operations—they drive up costs. That’s why inspection professionals rely on evoARC, evoSonic’s high-precision, non-contact axial encoder built for zero-maintenance performance in the most demanding environments.

Lightweight, rugged, and ready to deploy in seconds, evoARC is designed to eliminate scanning disruptions before they happen—delivering consistent data with fewer touchpoints and zero hassle.

What Makes a Maintenance-Friendly Scanner?

Unlike traditional encoders that rely on moving parts, physical contact, or frequent adjustments, evoARC is a non-contact circumferential axis encoder designed for fast, accurate scanning—without the wear and tear.

Key Design Advantages:

• Non-contact encoding for precise data without drag or friction

• Visual LED alignment—clearly marks 12, 3, 6, and 9 o’clock positions

• Tool-free mounting for ultra-fast setup and takedown

• IP67-rated, MIL-STD-810G tested for rugged field use

• No line marking required—get straight to scanning

Its streamlined, intuitive operation reduces prep time, training requirements, and equipment maintenance—keeping inspections on schedule and on budget.

Introducing evoARC: Compact, Contactless, and Built for the Field

evoARC is a compact axial encoder engineered to integrate seamlessly with third-party scanners like Olympus FlexoForm™ and other PAUT systems. At just 53g (< 2 ounces) it brings precision positioning and advanced data tracking into even the tightest inspection environments.

Quick Specs & Benefits:

• Axial data tracking with 0.013mm precision

• LED feedback system for precise alignment

• No wheels, no surface drag, no cleanup

• Suits circumferential weld inspections with A10, A31, and other mounts

• Plug-and-play compatibility with standard Lemo 1K.316 connectors

evoARC helps you work faster, more consistently, and with confidence.

Boosting Inspection Efficiency in the Field

evoARC reduces scanning friction—literally and figuratively. By eliminating traditional surface-contact elements and removing the need for scan-line markings, inspections are not only faster, but also more repeatable.

Key Efficiency Gains:

• Shorter setup times—mount in seconds without tools

• Fewer retakes thanks to high-resolution positional accuracy

• Improved inspection consistency across teams and job sites

• Minimal training requirements for operators at all levels

In high-pressure inspection environments, these small gains become major time and cost savers.

Use Cases: Where evoARC Excels

Oil & Gas
Eliminate line marking and reduce setup errors when scanning long pipe runs or tie-ins.

Industrial Plants
Quickly scan tanks and vessels with high reliability—without stopping production.

Why Maintenance-Free Matters

Unlike older encoder systems that require constant upkeep, recalibration, or fragile wheel systems, evoARC offers a true maintenance-free solution by design:

• No moving parts to wear out

• IP67 and MIL-STD-810G certification for rugged environments

• Non-contact technology eliminates drag, cleanup, and scanner drift

• Longer lifespan and more consistent performance across inspections

The result: less downtime, fewer interruptions, and higher quality inspections that stick to schedule and budget.
