EEC-39 Four Frequency Eight Channel Eddy Current Meter

Four frequency eight channel eddy current meterFunctional Information

·Four independent selectable frequencies
·Automatic/manual measurement of phase and amplitude
·Real time sixteen trace eddy current signal memory
·Defect amplitude, depth phase curve display
· *Non equal amplitude phase/amplitude alarm
·Expandable C-scan display function
·Optical discs and hard drives record/store/reproduce the signal waveform of the entire detection process
·Equipped with software for creating tube sheet diagrams
·Implement multi parameter detection: It can simultaneously obtain differential signals reflected by four frequency signals, eight vectors of the signal (i.e. sixteen trace eddy current signals), and complete both flaw detection and wall thickness measurement simultaneously
·Three integrated processing (mixing) units: capable of simultaneously separating or suppressing three sets of interference signals
·High signal-to-noise ratio: Due to precise hardware design and the application of low-noise synchronous filtering methods, the detection sensitivity of the instrument has been improved while reducing noise
·Automatic real-time signal processing: The instrument can store, process, and replay (call at any time) detection parameters or eddy current detection signals
·High intelligence instrument: This instrument has real-time menu prompts, human-machine dialogue, keyboard operation functions, to a large extentEliminating human errors during the detection process
·Configurable eddy current signal automatic analysis and evaluation (NDE) system software: The eddy current signals collected by the instrument can be analyzed and processed through the internal system software, and the position (row and column numbers) of the defect tube and the severity of the defect can be displayed on the screen in the form of a color chart
·Two four frequency and four channel detection systems can be set up, connected to two probes

Application field

·Suitable for non-destructive testing and wall thickness measurement of various in-service copper, titanium, aluminum, zirconium and other pipelines in sectors such as nuclear energy, power, petrochemicals, aerospace and aviation. It can obtain defect status and wall thickness reduction eddy current information of the pipes in one go, effectively suppressing interference signals caused by support plates, dents, sediments and cold processing of pipes during in-service testing
·Can be used for detecting cracks in the center hole of steam turbine shafts, blades, aviation engine blades, internal cracks in screw holes, aircraft landing gear, wheel hubs, and subcutaneous defects in aluminum masks
·It can also be used for evaluating the carbon content of carbon steel pipes (such as 10 # and 20 # steels) and other mechanical components' heat treatment status, measuring the depth of carburized layer and hardness, etc
