Product Introduction:
Xsn-tc-01 cable fault tester adopts acoustic vibration sensor with special structure and special device with low noise for preamplification, which greatly improves the sensitivity of fixed point and path detection. In signal processing technology, digital display of the distance between the fault point and the sensor probe, greatly eliminate the blindness of fixed point. For the fault cable overhead in the cable trench, in the past fixed point, the vibration sound of the whole cable makes any fixed point instrument helpless, unable to determine the specific location of the sealing fault. Now, as long as the sensor probe of the instrument is in contact with the fault cable or nearby cable, the fault distance and direction can be accurately displayed, and the fault location can be quickly determined effortlessly. In addition, adaptive power-frequency cancellation theory and high-Q power-frequency notch technology should be used to greatly strengthen the suppression and anti-interference ability of 50Hz power-frequency signal in the strong power-frequency electric field environment, and reduce the fixed-point blind area. In the function of the instrument, the difficulty of fixed point caused by environmental noise is overcome effectively by using the technology of acoustic and electric synchronous receiving and displaying. In particular, the digital display of fault distance saves the operator's analysis and judgment of complex waveform and to a considerable extent replaces the function of the flash meter to measure the rough distance. For hundreds of meters long fault cable, it can be fixed without rough measurement, which is really efficient, fast and accurate. Using 16kHz amplitude modulation electromagnetic wave and amplitude detection technology for path detection and cable buried depth measurement, avoid the interference of TV line frequency to the fixed point meter when the original 16kHz constant signal source.
