Eddy current testing system subject to EN 12084 with digital systems technology. For automatic, highresolution, multi-channel online flaw testing of components at automotive and machine industry. Universal testing system, adaptable for individual applications and requirements Real-time visualization of the test process with original signal display Comprehensive test documentation for each component and each flaw Continuous monitoring of operating safety Clearance compensation with automated adjustment

Features Simplified device adjustment based on data of material and test mechanics Continuous process control with display and monitoring of the noise level response Sensitivity adjustment can be automated with test flaw or noise level as reference parameters Operator interface protected against unauthorized access by an access code Gain correction of test channel via clearance compensation at geometric tolerances or excentricity The operating software is based on WINDOWS and provides TCP/IP interfaces to other WINDOWS programs Tested adjustment sets can be stored on the hard disk or...

Typical application Fully automated crack detection in the production line by the use of integrated handling systems. These are positioning and rotating the test parts as well as positioning and proceeding the probes. Using static, moved or rotating surface probes it's possible to scan several test zones in parallel or sequential for surface cracks. Following the parts are sorted into groups automatically according to the respective test result. Brake disc testing, wheel hub testing Fig. 1: Four probes are scanning the relevant zones of the brake disc Fig. 2: Probe pusher puller unit with...

Valve testing Fig. 5: High testing rate by multi-channel system. Some probes are stationary, others are proceeded. Drive shaft testing Fig. 6: Schematic diagram of an automated testing process with network connection for evaluation and saving of test data

Operating principle For crack detection the surface of the part to be tested is scanned contactless by one ore more eddy current probes. Thereby the "punctiform" acting surface probe records only a small area of the whole material surface at any given moment. Thus, a smallest material flaw crossed by the probe represents a large disturbance with respect to this small section. From this the high resolution for crack detection results . The excitation current I excites a primary magnetic field, which generates eddy currents in the test surface. This eddy current is influenced by cracks and is...
