PCS
Probe Centre Separation
PCS – Probe Centre Separation is the distance between the index points of the two ultrasonic probes used in a time-of-flight diffraction (TOFD) inspection. The PCS influences the accuracy of TOFD measurements. The spatial resolution can be improved and the dead zones at both surfaces can be reduced by decreasing the PCS.
For information on PCS, see:
BSI 24/30475245 DC – Draft BS EN ISO 16828 Non-destructive testing – Ultrasonic testing – Time-of-flight diffraction technique for detection and sizing of discontinuities.
This document will start final approval in June 2025 prior to issue.
When issued it will supersede: BS EN ISO 16828:2014 Non-destructive testing – Ultrasonic testing – Time-of-flight diffraction technique as a method for detection and sizing of discontinuities.
