Valve leak detector SVLD1

gasliquidacoustic

Features： Using acoustic emission technology, high detection accuracy, simple operation, small size, long endurance. Through acquisition, processing, and calculation of acoustic emission signal of the valves, SVLD1 could generated root-mean-square voltage (RMS), average signal level (ASL) and power (P) parameters as which could judge the leakage. Meantime, you can pre-calibrate the leakage quantity for the specified valve, and calibration curve of parameters and leakage could be calculated by SVLD1, so as to give the valve leakage reference value during the test. • Apply acoustic emission technology, easy to operate, keyboard shortcuts setting, complete leakage detection with only one button • RMS, ASL, Power parameters of leakage are applied. The known valve leakage can be calibrated, after calibration, the leakage reference value is displayed during measurement • FFT frequency spectrum analysis • Up to 200 kinds of different valves are available, each kind of valve can store up to 8 calibration curves • 16 bits sampling precision, sampling frequency can be adjusted freely • 6 kinds of analog filters • 100 hours working time, replaceable battery • Compact design, easy to carry • Beeping and flashing alarm, 2 grades alarm function, alarming data can be saved automatically • Data storage by one button with time simultaneously, data storage volume can achieve 50,000 groups • High speed data communication by USB interface
