ClearWave® Conventional Ultrasound Visual Enhancements
The EPOCH® 1000 series features a new and exciting set of visual enhancement capabilities to improve the quality and ease of detection in advanced applications.
- SureView®
- This feature emulates the functionality of analog CRT displays, allowing you to visualize peak indications from reflectors by adding a point of light along the A-scan trace where every peak occurs.
- Composite A-scan
- This feature uses every A-scan acquired in between screen update rates (multiple A-scans when PRF > 60 Hz) to draw a composite A-scan based on the maximum envelope of all the acquired A-scans.
- Max Amplitude
- This feature displays only the acquired A-scan with the highest gated amplitude reading between screen updates.
- Persistence Mode
- This feature provides visual “memory” of an inspection for enhanced visual detection over a short period of time.
- Baseline Break
- This feature displays “zero-cross” points as lines connecting individual A-scan lobes to the baseline in full-wave rectified mode.
- Min Thickness
- This feature displays only the A-scan representing the minimum thickness reading between screen updates.
- Averaged A-scan
- This feature enables you to view the average of the acquired A-scans. Averaging is applied in multipliers of 2x, 4x, 8x, 16x, 32x, and 64x.
Phased Array Imaging Package
with Advanced Conventional Ultrasound
The EPOCH® 1000i provides powerful conventional ultrasonic and phased array flaw detection in a portable, rugged instrument. This instrument provides the same reliable and exceptional performance for conventional detection as the EPOCH 1000, with the added benefit of phased array capabilities. The EPOCH 1000i allows you to perform code-compliant inspections in accordance with conventional standards, with the advantage of phased array for increased accuracy and efficiency.
Combined A-scan and S-scan Views
The EPOCH 1000i features a standard combined A-scan and S-scan view that displays A-scan data from every angle between two user-defined start and end values.
Calibration Across All Focal Laws
These automated calibration procedures allow you to capture peak amplitude or TOF/ distance measurements from a single reflector across all the imaging angles (focal laws).
Phased Array Features for Manual Imaging Inspections
Standard DAC/TVG for All Focal Laws
The EPOCH 1000i comes standard with DAC/TVG for all focal laws. After completing the setup, you can use the S-scan image to detect potential defects at various focal laws.
Standard Phased Array DGS/AVG
The DGS/AVG flaw sizing technique is included as a standard option in phased array mode. This feature uses the probe ID and wedge information to establish the DGS/AVG curve characteristics and applies the curve at 0°, 45°, 60°, and 70° focal laws. The standard EPOCH onboard DGS/AVG menu and modified GAIN calibration tool allow for quick and easy setup.
EPOCH 1000i Multi-Angle
The EPOCH 1000i phased array mode includes a standard feature called Multi-Angle. This feature enables you to designate any three angles, or focal laws, available in the sector scan as “visible” focal laws. This feature is perfect for inspectors using conventional sizing methods requiring evaluation at 45°, 60°, and 70°.
The True Depth gates display as horizontal lines on the S-scan only; the A-scan view remains in Soundpath mode.
AWS Weld Rating
The EPOCH 1000i comes with an AWS D1.1/D1.5 weld rating calculator
Linear Scans and Encoded C-scans
Linear scans are collected using a probe with up to 64 elements and a maximum active aperture of 16 elements.
C-scan imaging is created by accumulating image data from the programmed linear scan or S-scan across a single-line scan axis. An encoder is required to track the position as the probe is moved along the scan axis. Compressed A-scan images can be stored for all points on the C-scan, and can be reviewed along with the S-scan or liner scan from a particular C-scan location for basic visual analysis. Data source and type can be adjusted dynamically after the scan is acquired, and cursors are available for basic scan sizing. Additional color palettes are available for phased array image scans. These color palettes provide different color scales for use with varied applications and can be modified to meet your specific needs.
The EPOCH® 1000 series is designed to meet the IP66 environmental rating. Tested for shock, vibration, explosive atmosphere, and wide temperature range, these instruments can withstand operation in harsh inspection conditions. Some of the EPOCH 1000 series’ other key physical features include:
