9 Testing instruments and probe manufacturing Concerning your complex test task, we offer you customized test equipment for your manual or automated quality control. Our qualified and motivated team develops and manufactures multi-channel testing instruments, probes and cables for the eddy current and ultrasonic inspection. The PLR s own test equipment meets, respectively surpasses, a variety of individual customer requirements of most different branch of industries for example railways, automotive industry and aerospace. The portfolio of our test equipment includes the sorting of different materials and the inspection of surface-open as well inner damages. Due to our quality management system DIN EN ISO 9001, we are committed that our products can be efficiently manufactured with high quality. Our testing instruments and probes meet the current normative requirements. We assist you in all life cycles of the test equipment. We carry out the assembly, approval, maintenance and repair of the test equipment.

TESTING ENGINEERING 10 Development and design of individual system solutions specially adapted to customer requirements 2006 Equipping the rail inspection trains of Deutsche Bahn AG with eddy current and ultrasonic inspection technology starts 2007 Inspection of the large rotor wing type E 126-series starts

11 Development and design We offer you a fitted all-in-one solution for the performance of automated inspections of NDT tasks. Your customer requirements are regularly implemented in hardware and software. Software connections to customer controls and databases are developed and implemented according to the requirements. Our software solutions simplify the processing of complex test task. Multi-lingual visualization of the user interface offers international transparency. Connections to existing industrial environment and manipulators influence the design-related realization. Provided 3D models (Inventor, Step) as well as drawings in 2D format can be applied. Additional functions can be realized by our hardware developer as well as single electronic solution or implementation of hardware-related programming (FPGA) in the test electronics.

TESTING ENGINEERING 12 Eddy current and ultrasonic inspection at laid rails 2011 Begin of NDT test of components for ITER research project 2012 Launch of the handheld eddy current inspection system WPG NT (New Technology)

13 Rail inspection systems High infrastructure, safety and availability requirements demand a continuous and effective analyse of the track state by using of non-destructive testing methods. PLR s eddy current and ultrasonic inspection systems create data, which are provided by an expert system for the rating of the rail quality or maintenance planning. The integration of automated ultrasonic and eddy current inspection systems at rail inspection trains allows the simultaneous detection and analyse of surface and volume defects. The use of automated eddy current inspection systems at reprofiling trains enables the maintenance performance as well as the proof of the successful performance of reprofiling. The handheld eddy current inspection systems developed by PLR for the one-sided and double-sided rail and switch inspection are based on the same algorithms of data recording and representation of results as used for automated rail inspection and provide compatible inspection results.

TESTING ENGINEERING 14 Inspection equipment for the quality assurance in the automotive and aerospace industry 2012/13 Equipping of 10 rail reprofiling machines with the PLR eddy current inspection system 2013 Equipping the rail inspection train of the Hungarian National Railway (MAV)

15 Automotive and aerospace Modern materials and complex geometries for the automotive and aerospace industries and their suppliers require a high degree of precision and performance to the test equipment. In addition to a high detection capability, process reliability at full utilization and intuitive operation are essential criteria. from the serial test of mass parts (rolling bearing body, valve shafts, battery contacts for electric vehicles) over temperature-independent sorting of material properties (engine bearer) to the manual crack detection at hidden test positions (helicopter engine, sprocket wheel of camshafts). The quality of components can be ensured by the equipping of automated test facility as well as handheld test instruments with PLR test technology for eddy current and ultrasonic testing. The range of test task extends
