The ECT48 Eddy Current Testing System

Eddy Current Technology Incorporated

The ect 48 Specifications (SI)

Simultaneous Sampling (SS)

Up to 12,000 Hz sample rate, each channel, allows up to 10 feet per second probe speed at over 100 samples/inch.

Automatic data analysis.

Save and recall unlimited test setups.

Defect signals are highlighted in real time during recording or
playback.

Four independently selected simultaneous frequencies.

Digital Signal Processing (DSP) HP & LP filtering provides lower
noise.

Independent horizontal and vertical display scaling.

Signal phase and amplitude measurement functions.

Defect depth measurement functions.

Standard printer interface.

Single keystroke data acquisition.

Single keystroke data playback with analysis.

Optional ect 48 Data Analysis Software.

Optional ect Frequency Transforms* use eddy current signals in
the frequency domain, making it easy to
distinguish between magnetic inclusions, roll stops, and serious defects.

Optional ect Data Storage Software stores and recalls
eddy current signals on disk.

Optional ect Report Software reads the defect listprovided by
the ect 48 Data Analysis Software and provides tube sheet maps
color-coded based on defect depth.

16 16-Bit Analog-to-Digital Conversion so all channels are sampled in
the same microsecond.
