EEC-39 Four Frequency Eight Channel Eddy Current Tester Detailed Dynamics

The EEC-39 has the following characteristics: 1. It can achieve multi parameter detection: it can simultaneously obtain differential signals reflected by four frequency signals, eight vectors of signals (i.e. sixteen trace eddy current signals), and complete flaw detection and wall thickness measurement simultaneously. 2. Three integrated processing (mixing) units: capable of simultaneously separating or suppressing three sets of interference signals. 3. 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. 4. Automatic real-time signal processing: The instrument can store, process, and replay (call at any time) detection parameters or eddy current detection signals. 5. High intelligence instrument: This instrument has real-time menu prompts, human-machine dialogue, keyboard operation functions, eliminating human errors in the detection process. 6. 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 system software inside the machine, 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. 7. Two four frequency and four channel detection systems can be set up, connected to two probes.
