Single channel eddy current test instrument for automated testing tasks The single channel test instrument, designed with protection class IP54, can be integrated directly into the production process, for example for automatic screw testing machines. It can be integrated into existing systems with minimal expenditure. With a frequency range from 10 Hz to 12 MHz, a universal signal filter and I/O interface, this test instrument is an efficient alternative for fast crack detection and sorting tasks.
Rotor EC15 compact
Compact EC15 rotorCompact high-performance rotor for the non-contact testing of round materials, such as wires, rods and pipes with dimensions ranging from 1.5 – 15 mm, are able to pass through it. Constructed in a high-strength anodized aluminum housing, this rotor serves to record longitudinal and transverse defects with longitudinal components starting from a defect depth of 20 ?. Its compact construction allows the rotor to be very easily integrated into existing test tracks or transport lines. The median throughput height is 35 mm.
The focus of the new instrument family is the fully digitized signal processing chain on the NF-side (after demodulation) with a bandwidth of 10 kHz and ultrafast multiplexing capability featuring a multiplexing rate of 32 kHz (probe to probe). The full dynamics of 96 dB (digital) across the frequency range from 10 Hz to 12 MHz speak for themselves. The display is something special, too: The display of an analog tube is simulated in a digital manner with adjustable persistence and so far unmatched definition and brilliance– simply the best analog display, if it wasn’t digital and thus a effective combination of traditionally proven and modern technology.
Excellent performance in a small footprint, ligthweight tabletop housing
The new ELOTEST M3 is based on the small and powerful ELOTEST M2, well known as the smallest handheld eddy current tester on the market. The ELOTEST M3 offers a large size LCD display with stunning definition and brightness. When multiple inspectors have to review images for evaluation or precise handling of the probe does not allow capability of holding the instrument, the M3 will be the instrument of choice based on the large display and intuitiveness of the parameter adjustments.
Some of the exceptional performance data are listed below:
The main application fields for the ELOTEST M3 are manual surface inspection, bore hole inspection, hidden structure as well as conductivity and coating thickness measurements.
What is SICOR?
SICOR is an acronym for “Speed Induced Current On Rails”. It describes a new measuring procedure for the examination of fitted railway rails for sub-surface (hidden) defects on the rail head, especially at depths of 1-10 mm below the surface. Thus the previously designated “problem zone”, too deep for the usual eddy current procedures and not deep enough for the usual ultrasonic methods, can be tested. The principles of the SICOR technique are explained below.
