Notes on EEC-35++Dual Frequency Four Channel Eddy Current Tester

The EEC-35++dual frequency four channel eddy current detector (notebook+portable host form) is particularly suitable for non-destructive testing and wall thickness measurement of various pipelines such as copper, titanium, stainless steel, aluminum, and zirconium in service and before service in the power, petrochemical, and other sectors. It can obtain the defect status and wall thinning eddy current information of the pipes in one go, which is an advantage that ordinary dual frequency eddy current detectors do not have. The detection can effectively suppress interference signals caused by support plates, dents, probe shaking, sediment, and cold processing of in-service pipes; This instrument can also be used for detecting defects such as cracks in the center hole of the turbine shaft, blades, bolt holes, and other mechanical components; It can also be used for pre service inspection of steel pipes such as boiler tubes, oil pipes, water and gas pipes, etc.

Precautions for dual frequency four channel eddy current detector

Function information:

·Two independent selectable frequencies
·Automatic/manual measurement of phase and amplitude
·Non equal amplitude phase/amplitude alarm function
·Store/reproduce the signal waveform of the entire detection process
·Multi parameter detection: can simultaneously obtain the differentialThe four vectors of the signal (eight trace eddy current signal)
·Multiple integrated processing (mixing) units: capable of simultaneously separating or suppressing multiple sets of interference signals. (Portable included)
·High signal-to-noise ratio: Due to precise hardware design and the application of low-noise synchronous filtering methods, the instrument provides detection sensitivity while reducing noise
·Automatic real-time signal processing: The instrument can store, process, and replay (randomly call) detection parameters or eddy current detection signals
·High intelligence instrument: This instrument has real-time menu prompts, human-machine dialogue, and keyboard operation functions,Eliminate human errors during the detection process
