Sonatest CT-Gage DL+ Ultrasonic Thickness Gauge - Advanced A/B-Scan, Data Logging & Time Corrected Gain (TCG)
Elevate your ultrasonic thickness measurement and flaw detection capabilities with the Sonatest CT-Gage DL+. This advanced, portable ultrasonic thickness gauge is designed for professionals who demand more than just a number – it provides crucial A-Scan and B-Scan visual data, robust data logging, and sophisticated Time Corrected Gain (TCG) for unparalleled accuracy and insight into material integrity.
Key Features & Benefits:
A-Scan Measurement & Storage: Unlike basic thickness gauges, the CT-Gage DL+ allows you to view the live A-Scan waveform (the raw ultrasonic signal). This is critical for:
Echo Verification: Visually confirm the integrity of the echo, ensuring you are measuring the correct reflection and avoiding false readings (e.g., from surface noise or internal inclusions).
Troubleshooting: Identify complex material conditions or challenging measurement scenarios.
Defect Detection: Recognize the presence of flaws (pits, corrosion, delaminations) by observing abnormalities in the A-Scan.
Data Archiving: Store A-Scans alongside thickness readings for detailed post-analysis and auditing.
B-Scan Measurement & Storage: Create a time-based cross-sectional view of the material under inspection. The B-Scan provides:
Profile Mapping: Visually map corrosion, pitting, and other material loss, offering a clear picture of remaining wall thickness over a scan line.
Documentation: Store B-Scan images as visual records of inspection areas.
Time Corrected Gain (TCG): This crucial feature automatically increases gain with time (and thus depth), compensating for material attenuation and beam spreading. TCG ensures that echoes from flaws or backwalls at greater depths appear at a consistent amplitude, improving:
Detection Sensitivity: Ensures small defects are visible regardless of their depth.
Sizing Accuracy: Aids in more accurate sizing of flaws.
Overall Measurement Reliability: Provides more consistent and interpretable A-Scan and B-Scan data.
Comprehensive Data Logger (DL): Store vast amounts of thickness readings with identifiable locations and B-Scan captures.
Sequential Logging: For quick, continuous data acquisition.
Alpha-Numeric Grid: For structured mapping and corrosion surveys.
High Storage Capacity: Can store thousands of readings and associated settings, allowing for detailed asset management and trend analysis.
Data Export: Easily transfer data to Microsoft Excel via the Data XL interface program for reporting and further analysis.
Multiple Measurement Modes:
Pulse-Echo (P-E): Standard mode for overall thickness measurement, also detects pits and flaws.
Pulse-Echo with Coating (P-E/C): Measures material and coating thickness simultaneously.
Echo-Echo (E-E): Measures true material thickness, ignoring coatings (through-paint capability).
Coating Only (CT): Measures only the coating thickness.
Pulse-Echo with Temperature Compensation (PETP): For enhanced accuracy in varying temperature environments.
User-Friendly & Robust Design:
Automatic Probe Recognition & Zero: Streamlines setup and calibration.
Automatic Gain Control (AGC): Simplifies gain adjustment.
Custom Rubber Boot (often included): Provides extra protection in harsh environments.
Compact & Lightweight: Easy to handle in the field.
IP67 Designed: Robust construction for dust and water resistance.
Versatile Applications:
Corrosion and Pitting Assessment
Thickness Measurement of Pipes, Tanks, and Pressure Vessels
Boiler Tube Inspection
General Material Thickness Verification
Quality Control in manufacturing, oil & gas, power generation, and marine industries.
