Distance-Amplitude Correction (DAC) Calibration: DAC blocks are used to calibrate ultrasonic testing (UT) equipment to account for the loss of signal amplitude due to the distance between the transducer and the test material, ensuring accurate measurements of flaws and defects.
Time-Corrected Gain (TCG) Calibration: TCG blocks allow for the calibration of ultrasonic systems to correct for changes in signal strength due to varying material thickness or distance, optimizing signal readings and improving flaw detection.
Improved Flaw Detection: These blocks ensure that ultrasonic devices provide consistent and accurate readings across varying distances and material thicknesses, helping identify flaws that might otherwise be missed.
DAC / TCG Blocks are essential tools for ensuring the accuracy and precision of ultrasonic testing equipment. These blocks provide a reference for Distance Amplitude Correction (DAC) and Time Corrected Gain (TCG), helping calibrate ultrasonic equipment for accurate flaw detection and material testing.
DAC blocks are designed to correct the loss of amplitude due to the distance between the transducer and the test material. This correction ensures that ultrasonic devices provide reliable readings, even for materials of different thicknesses.
TCG blocks help adjust signal strength to compensate for material variations, ensuring that ultrasonic devices maintain consistent sensitivity throughout the test.
These blocks are commonly used in welding inspections, material testing, pipe and tank inspections, and other non-destructive testing applications to ensure that ultrasonic equipment is calibrated to provide accurate measurements across varying conditions.
