What are the benefits of the LATITUDE?

LESS EQUIPMENT
LATITUDE is compact, portable, and battery powered
SMALLER CREW
LATITUDE is designed to be setup and operated by a single person
FASTER SETUP
LATITUDE adds minimal setup time to that required for a traditional manual examination
BETTER QUALITY
LATITUDE guarantees coverage and puts the probe back into a human hand, helping to optimize coupling and indication response

What is the LATITUDE?

LATITUDE is a non-mechanized position encoding technology that enable the digitization and recording of manual NDE inspections.

LATITUDE was used as the encoding technology on Structural Integrity’s recently qualified procedure, SI-UT-217 Rev 0. This procedure was qualified through the EPRI PDI (Performance Demonstration Initiative) program for application to nuclear plant dissimilar metal welds. LATITUDE is now considered a viable alternative for dissimilar metal weld examinations currently employing automated UT.

RECEIVER ARRAY

CONFORMABLE SELF-ALIGNING COLLAR FOR FLAT & CURVED SURFACES

The collar can be wrapped around the pipe circumference, stretched along the pipe axis, or be otherwise placed on any flat or curving surface. All wiring is self-contained and there is a single connection point to the LATITUDE electronics.

LATITUDE CONTROL UNIT

THE BRAIN OF THE SYSTEM

Responsible for collecting the air-born ultrasonic data, translating it into position information, and communicating with the NDE data acquisition system. It consists of a sealed fanless enclosure and is powered by two (2) hot-swappable batteries that provide ~10 hours of usage. The LATITUDE control unit can be attached to the rear of a PAUT instrument using a quick-release clip..

TRANSMITTER ATTACHMENT

MULTIPLE SENSORS DETERMINING AXIAL & CIRCUMFERENTIAL POSIITON

Typically affixed to an NDE sensor that is being used to conduct an examination, such as a PAUT probe, an eddy current testing (ECT) probe, or any of several other kinds of NDE sensors.

APPLICATIONS

DISSIMILAR METAL WELD EXAMINATIONS

Exceeding Section XI, Appendix VIII, Supplement 10

FABRICATION ACCEPTANCE EXAMINATIONS

UT in lieu of RT Exceeding ASME code cases, including Section III and XI, B31.1, B31.3

INTERNAL CORROSION MAPPING

LATITUDE, coupled with the use of a PAUT corrosion mapping probe, enables the encoding of high-resolution thickness data while manually manipulating the inspection probe, resulting in a composite thickness map that requires little to no post-processing for analysis.

GENERIC WELD EXAMINATIONS

LATITUDE encoded manual inspections provide proof of coverage and a digital record of the examination data at a fraction of the cost of typical automated or robotic examinations.
