NDT Equipment

ugged Handheld Flaw Detector

The EPOCH LTC digital ultrasonic flaw detector offers state-of-the-art technology in a compact and lightweight package. Based on the class-leading EPOCH XT, the EPOCH LTC is full featured, complies with the EN12668-1 standard, and has various specialized options to meet your inspection needs. 

Ultrasonic flaw detection is widely used in locating and sizing hidden cracks, voids, disbonds, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.

The EPOCH LTC features a bright, multi color transflective, full-VGA (640 pixelsx480 pixels) display offering high-resolution A-scans and superior visibility in all lighting conditions, including direct sunlight.  The EPOCH LTC is also IP67 rated, ensuring that the instrument can perform in the harsh environments common in the inspec tion field.

Powerful Performance in a Compact Flaw Detector

The EPOCH LTC offers many standard features to meet your inspection needs. These include a square wave pulser, dynamic DAC/TVG, selectable digital filters, gain range from 0 dB to 110 dB, peak memory, 0.01 mm (0.001 in.) measurement resolution, and one gate with programmable alarms. In addition, the EPCOH LTC offers many optional, application-specific software features such as onboard DGS/AVG, AWS D1.1/D1.5 weld rating, manual PRF control, pulse width tuning, Gate 2, curved surface correction, and the GageView Pro interface program.

Simplified Keypad Design

The EPOCH LTC features a simple keypad design that allows full control with the left or right hand for direct access to important functions. The keypad design also makes for rapid and easy parameter adjustments and recall of instrument configuration (CAL) files.

The keypad is available in English, interna tional symbols, Japanese, and Chinese.

Four custom function keys allow opera tors to select preset values for instrument configuration parameters.

Advanced Software Features and Data Management

Standard dynamic DAC/TVG: Calculates signal amplitude as a percentage or decibel level compared to a DAC curve or a reference echo amplitude fixed at a time-varied gain. DAC versions include ASME, ASME3, JIS, and Custom. Also includes several key features:dynamically adjustable DAC curves, switchable DAC and TVG views, and custom DAC warning curves.

SOFTWARE OPTIONS

DGS/AVG: Flaw sizing technique allowing echo signals to be evaluated with a DGS/AVG diagram associated to a particular type of probe and material. The DGS/AVG diagram illustrates the relationships between echo height, flaw size, and distance from the transducer (PN: EPLTC-DGS-AVG).

Gate 2 (Echo-to-Echo): Activates Gate 2 in the EPOCH LTC, allowing Gate 2 measurements , Echo-to-Echo measurements, and Gate 2 alarms (PN: EPLTC-GATE2).
