Eddy current unit tests at higher speeds
Designed for 'in-line' testing of products and fabricated joints, an eddy current tester offers higher testing speeds, very high sensitivity and high resolution.
The Elotest PL 500 is the first eddy current test instrument of the V5-family is faster, higher, more powerful, said Rohmann It has very high test speed, very high sensitivity and very high resolution and dynamics

Coordinate metrology services are cost-effective
Providing fast, flexible and cost-effective coordinate metrology services to manufacturing sector customers throughout the UK, a new company carries out work on components up to 2m3.
Car navigation and telematics tested automatically
Today's automobile is already a vast network of interconnected silicon chips, controlling everything from airbags to engines operations. Alfautomazione has systems to test them.
Specifically designed for inline-testing, the V% testers have a 19in and 4HU industrial housing and features up to 16 plug-in modules.
By using additional racks, it may be expanded to 256 plug-in modules.
The modules could be fully synchronised test channels, distance compensation modules, I/O modules, or customer-specific evaluation modules.
The PL500 instrument has the following features.
* A digital signal processing chain on the low frequency side (after demodulation).
* Extremely large bandwidth of 100kHz.
* Ultra-fast multiplexing-capability featuring a multiplexing rate of 50kHz for 64 channels.
* Full dynamics of 96dB (digital) across the entire frequency range from 1Hz to12.5MHz.
* Full dynamics and extremely low noise guarantee crisp eddy current signals.
* The display is an analogue tube is simulated in a digital manner Inspection applications include the following.
* Inspecting long products (e g, wires) at a very high speed and great precision using fast rotors during the production process.
* Rail-inspection trains could inspect the railway system under the same conditions as today, but at the speed of an ICE high-speed train.
* Riveted seams (e g, longitudinal) on aircraft stuctures inspected at high speed.
* Probe-arrays with 64 elements could inspect material surfaces with test speeds of up to 1m/s.
