Surface probes are manufactured with a flat face on the underside to allow for more stable use on the element being tested. There is a range of frequencies available with all probes being shielded.
Probes can be purchased in absolute mode and in bridge (SS) or reflection (SSR) configurations.
The US-3716 is a general-purpose probe that can be utilized in many different surface inspections. Well balanced differential coils exhibit minimal lift-off signal and can be operated in a broad frequency range. The coils are directionally sensitive allowing for detection independent of orientation. It’s a cost-effective method to inspect in-service welds efficiently for near surface cracks and can be used to inspect through thin coatings such as paint.
