Options for Comfortable Navigation

In order to accommodate different user needs and preferences, the EPOCH 650 is available in two hardware configurations:

Knob

The adjustment knob on the EPOCH 650 is used along with the CHECK and ESC keys to adjust parameter values in either coarse or fine increments. You have the ability to lock the knob to prevent accidental parameter value changes during an inspection. This configuration provides smooth value slewing for customers who prefer adjusting parameters using a knob. The knob configuration is designed to meet the requirements of IP66.

Navigation Pad

The EPOCH 650 navigation pad is a hallmark feature of the EPOCH flaw detectors. The up and down arrows on the navigation pad are used for coarse parameter adjustment, and the left and right arrows for fine adjustment. The navigation pad also contains additional functions and frequently used parameters such as gain, save, and the CHECK and ESC keys. The navigation pad configuration is designed to meet the requirements of IP67.

Software

Optimized Access to Powerful Features

The EPOCH 650 provides excellent quality ultrasonic performance. Based on the same digital architecture as
the EPOCH 600 and EPOCH 1000 Series, the EPOCH 650 provides flexible, powerful pulsing and receiving features to accommodate the needs of most flaw detection inspections.

Pulser/Receiver

The EPOCH 650 comes standard with powerful flaw detection capabilities, such as:

PerfectSquareTM tunable square wave pulser
Digital high dynamic range receiver
Thirty (30) 100% digital filter sets
Auto or manually adjustable PRF from 10 Hz to 2000 Hz
Pulser voltage from 100 V to 400 V
Amplitude resolution to ± 0.25%
Five customizable digital measurements

EPOCH 650 Echo-to-Echo with Gate Tracking

Standard Software Features

Dynamic DAC/TCG: 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 Standard, ASME 3, JIS, and Custom. Also includes several key features: dynamically adjustable DAC curves, switchable DAC and TCG views, custom DAC warning curves, and 20-80% DAC views.

DGS/AVG: This flaw sizing technique allows 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.

AWS D1.1 and D1.5: Provides a dynamic reflector indication rating for various AWS weld inspection applications. This allows more efficient inspections by eliminating manual calculations.

Versatility Through Optional Performance

Optional Software Features

Interface Gate: This optional third measurement gate enables real-time tracking of a variable interface echo in order to maintain consistent digital measurements.

Corrosion Module: Simplified corrosion mode allowing automatic ultrasonic setups based on transducer selection, Automatic Gain Control (AGC), thickness gage measurement algorithm, V-Path correction, and transducer wear compensation using an automatic zero function (“Do Zero”). Also features color-coded Grid View and encoded B-scan.

EPOCH 650 Template Storage Feature

Template Storage: Allows on-screen comparison of a live waveform with a saved reference waveform. Saved templates can be dynamically toggled on and off with a single key press for fast waveform comparison. Excellent for spotweld analysis and other applications.

Backwall Echo Attenuator (BEA): Attenuates the backwall of an inspected part using the screen region defined by Gate 2.

API 5UE: Allows defect sizing according to API Recommended Practice 5UE. Uses the Amplitude Distance Differential Technique (ADDT) to measure the size of
potential defects during the prove-up process of OCTG pipe.

Waveform Averaging: This feature allows live A-scan averaging 2X, 4X, 8X, 16X, and 32X.

Data Logging and PC Interfacing

Data Management

The EPOCH 650 allows several methods of storing, archiving and reporting inspection and calibration data.

The instrument features up to 100,000 points of onboard memory, as well as video recording and review. It is also fully compatible with Olympus PC interface program, GageViewTM Pro. With quick file setup functions and flexible data management, logging and reporting inspection data is simple and efficient.

On-board Reporting

The EPOCH 650 allows report generation on-board in a variety of formats. You can easily capture screen shots to the removable microSD card, as well as exporting saved data in .csv or .xml files. The instrument also features Bitmap report generation for single data points or entire files.

The EPOCH 650 comes standard with a video recording feature. You can capture up to 8 minutes of the live A-scan inspection data at 60 frames per second. This data can be reviewed on the EPOCH 650 or exported for review on a PC.

Data Logger

The EPOCH 650 features an onboard data logger for calibration and inspection file storage. The instrument comes with two primary file types: calibration (CAL) and incremental (INC) files. CAL files allows you to save a virtually unlimited number of parameter setups for fast and easy recall to live settings. INC files store multiple pieces of inspection data under a single file name for downloading and reporting by inspection.

The onboard data logger is enhanced by full featured corrosion-style data logger file types standard on the EPOCH 650. This feature includes the following data file types: sequential, sequential with custom point, 2-D grid, 2-D grid with custom point, 3-D grid, boiler, 2-D EPRI.

GageView^TM Pro

The EPOCH 650 is fully compatible with our PC interface program, GageViewTM Pro. You can download inspection data, review measurements on a PC, export measurements and calibration data to common spreadsheet programs, back up calibration and inspection data from the instrument, and perform basic operations such as instrument firmware upgrades and screen captures.

MicroSD

The EPOCH 650 utilizes an external microSD memory card (2 GB included, up to 64 GB supported) for both onboard and removable memory. Through removable memory, you are able to share files between instruments, as well as output reports in various formats. A second 2 GB microSD card is mounted to the PC board inside the instrument, and is responsible for all onboard data storage. In the event the instrument is damaged beyond repair, this microSD card can be removed at an authorized service center, allowing the operator to recover critical data from the damaged instrument.
