Pulse-Echo and TOFD Inspection Solution
The PV-100 solution is based on the proven OmniScan® UT flaw detector. This advanced UT instrument uses two inspection techniques simultaneously. The combination of time-of-flight diffraction (TOFD) and the pulse-echo or creeping wave technique allows a full volumetric inspection in a single pass.
Inspection results are available instantaneously providing immediate code based acceptance or rejection. This solution was specifically designed to meet the productivity requirements of construction welding in petrochemical and power-generation industries.

Combining Different Techniques for Improved Efficiency and POD
Pulse-echo channel, 60º shear wave for weld cap coverage.
Pulse-echo channel, 70º shear wave for weld root coverage.
TOFD channel for weld volume coverage.
Combining pulse-echo and TOFD channels offers complete coverage of the weld.

PV-100 Options
Umbilical cables
Two different umbilical cables are available:
- The closed-type umbilical offers the most rugged protection. It covers the cable with a resistant, waterproof, and dust proof conduit.
- The divisible type is composed of two split shells that protect the cables. Although not as rugged as the closed-type umbilical, it offers other advantages: the cables inside the umbilical can be changed at any time.
CFU03 - Electric Couplant-Feed Unit
The CFU03 is a portable electrical pump unit used to supply couplant to wedges during ultrasonic inspections.
WTR-SPRAYER-8L - Manual Couplant-Feed Unit
The manual feed unit offers a cheap and efficient way to supply couplant to wedges during automated inspections.
TRPP-5810 - Remote Pulser/Preamplifier for TOFD Inspection
The TRPP-5810™ unit is a high-performance remote pulser/preamplifier dedicated to TOFD inspections and compatible with Olympus industrial scanners.
Panametrics 5682 - Preamplifier for TOFD Inspection
The Panametrics 5682 ultrasonic preamplifier provides low-noise amplification of ultrasonic signals (for one probe) ranging from 500 kHz to 25 MHz.
