Overview

Product overview

Sensu 2 is a family of topside alternating current field measurement (ACFM) probes for the Amigo2 inspection system. The range offers faster operation than legacy probes, improved signal quality and higher signal-to-noise ratio. Configuration data resides in each probe, while integrated buttons and status LEDs support control and feedback during scanning.

Probe configurations address different weld inspection tasks. The compliant array uses 8 or 16 ACFM sensors, dual fields and an integrated encoder to cover ferritic welds across 90mm (3.5in). The weld probe provides stabilizers and a wider field for ferritic or austenitic welds, while the pencil probe offers straight, right-angle and transverse nose configurations.

For carbon steel fillet welds, the dedicated array covers the toes, cap and heat-affected zones in one pass. Its 3Bz sizing method combines two additional Bz sensors per ACFM element with a software algorithm to determine crack length and depth without mechanical encoding or manual surface measurements. Assist software supports pre-programmed inspection sequences controlled from the probe.

Specialized solutions extend inspection to galvanized steel and hot components. The galvanized steel configuration detects and sizes cracks penetrating conductive coatings up to 300μm thick; cracks beneath the coating can also be detected, with coating removal required for accurate sizing. The high-temperature probe combines air cooling, cooling warnings and selectable factory calibrations for inspection from 0°C (32°F) to 500°C (932°F), supporting in-service weld inspection and welding interpass checks.

Key Features

Key capabilities

Intelligent probes

Probe memory stores configuration information and probe data.

On-probe controls

Integrated buttons start or stop scans, and LEDs indicate scanning status.

Connectorized cables

Connectorized construction allows probe cables to be swapped easily.

IP65 protection

The probe range is IP65 rated.

Compliant array coverage

The compliant array combines dual fields, an integrated encoder and 8 or 16 ACFM sensors for ferritic weld inspection.

Flexible probe geometries

Weld probes use stabilizers and a wider field, while pencil probes offer three nose orientations.

Single-pass fillet weld inspection

The fillet weld array covers weld toes, cap and heat-affected zones simultaneously without moving parts.

3Bz crack sizing

Fillet weld and high-temperature solutions use additional sensors and software analysis to size cracks without mechanical encoders or surface markings.

Inspection planning

Assist software organizes fillet weld inspections into pre-programmed sequences operated through probe buttons.

High-temperature safeguards

The high-temperature probe uses air cooling and a red illuminated nose to indicate when cooling is required.

Operating conditions & limits

The compliant array is intended for ferritic welds and supports a maximum cable length of 50m (160ft).
The fillet weld array application described is for carbon steel fillet welds.
Galvanized steel detection and sizing through conductive coatings up to 300μm thick applies to cracks that penetrate the coating.
Galvanized steel inspection requires a preliminary assessment of zinc coating condition and thickness.
For accurate sizing of cracks beneath conductive coatings, coating removal within a 50mm (2in) radius around the crack and use of a standard configuration are recommended.
High-temperature inspection is specified from 0°C (32°F) to 500°C (932°F); the part temperature must be measured and the appropriate calibration selected.
The high-temperature probe requires cooling when its nose illuminates red.
