Description: Ultrasonic test instrumentation and control electronics are for on- or off-line inspection of tube, bar or plate. The significantly enhanced product is designed for flaw detection and measurement of wall thickness and outside diameter (OD) in both tube and pipe applications. Additionally, the flexible FD-4 is suitable for use in both new installations and retrofit applications using existing transducers. With 32 test channels in a single system, the FD4 features outstanding test performance in a Windows P platform. With the addition of OD and thickness measurement, the FD-4 can report ID dimensions, ovality, eccentricity, or wall variation. The equipment includes full network support for remote desktop viewing and control. The FD-4 instrumentation is well suited for new or older installations in need of upgrading. The FD-4 may be used either with MACS Echomac Rotary UT transducer assemblies, or with other immersion, squirter, spin- the-tube and C-scan plate ultrasonic systems. Using the FD-4's EchoHunter software, users may easily configure each channel for any combination of thickness and flaw detection. The strip chart portion of the simultaneous strip chart/A scan display shows peak signal values within each threshold gate for up to 16 channels. The flicker-free A-scan captures non-repetitive events such as short duration flaws, even during high-speed UT scanning typical of rotating transducer head systems. Display modes include basic sample and persistence modes with adjustable decay time. Additionally, the FD-4 offers a dynamic new 3-D mode in which the prior signals fade into the background as the displacement of the transducer and reflector changes.
