Which mechanical system is used for tracking the position of the probe on the part?

The encoder is a critical component in the mechanical systems used for tracking the position of a probe on a part during inspection. It operates by converting the physical position of the probe, often in linear or rotational movement, into a digital signal that can be interpreted by the associated data acquisition system. This capability allows for precise mapping of the probe's motion over the surface of the material being inspected, providing accurate spatial data that is essential for creating a detailed scan.

Encoders are typically designed to provide high accuracy and resolution, making them ideal for sophisticated applications such as phased array ultrasonic testing, where understanding the exact location of probe movements on the test object is vital for effective analysis and defect detection. By using encoders, technicians can ensure reliable data collection, leading to more accurate and repeatable results in inspections.
