Reusable laminated magnetic flux indicator strips for checking the effectiveness of magnetic particle inspection (MPI). Placed on the test surface during magnetisation, the built-in artificial indications help the operator confirm magnetic-field direction and that the combined field, particles, application technique and viewing conditions are capable of producing an indication.
Available types
- Type 1 / Type G – General Purpose: for general industrial MPI applications and higher-permeability ferromagnetic materials.
- Type 2 / Type A – Aerospace: a finer, more sensitive version intended for aerospace, critical-component and lower-permeability applications.
Features
- Pack of 5 strips
- Approximately 50 × 12 × 0.15 mm per strip
- Flexible three-layer construction with a magnetically soft core and non-magnetic protective outer layers
- Three parallel artificial indications
- Suitable for wet fluorescent, wet visible and dry magnetic-particle methods
- Can be used with longitudinal or circular magnetisation
- Reusable when handled and stored carefully
Important: These strips provide a qualitative indication of MPI test effectiveness. They do not measure field strength numerically and do not replace a calibrated magnetic field meter where quantitative measurement is required.
Applications
- Verifying magnetic field direction during magnetic-particle inspection
- Checking adequate field strength and part magnetisation
- NDT procedure setup and operator training
- Weld, casting and forged-component inspection
