The JT-3000 leak location leak detector is an instrument used to locate and determine the location of water supply pipeline leaks. It can also be used for leak detection in other pressure pipeline systems. When the fluid inside the pipeline escapes under pressure, noise can propagate along the pipeline or along the buried medium to the ground.
JT-3000 leak location detector/leak precise location detector is an instrument used to find and determine the location of water supply pipeline leaks, and can also be used for leak detection in other pressure pipeline systems. When the fluid inside the pipeline escapes under pressure, it generates noise and propagates along the pipeline or buried medium to the ground. This instrument can determine the location of leaks along pipelines or above their road surfaces.



1、 Instrument features
1. Digital processing: The water leakage precise positioning detector uses a low-power microprocessor and advanced filters to digitize the noise.
2. High sensitivity sensor: Equipped with a specially designed broadband high-sensitivity vibration sensor (pickup), it can convert ground (or pipeline) noise into electrical signals, which are then amplified and digitally filtered.
3. Display mode: Present the results on the LCD screen through two display modes. The leakage noise is a continuous signal, and a six frequency band rotation detection method is used to detect the continuous noise, generating six display rectangular columns and suppressing sudden impact interference (not displayed). Meanwhile, the small value method is adopted to minimize external interference to the greatest extent possible.
4. LCD display screen: Adopting a dot matrix type backlit LCD display screen, it meets the display requirements of six horizontal and vertical light columns, making it convenient for night observation.
5. Bandwidth and Channel: Specially designed with three levels of bandwidth variation (narrowband, medium broadband, broadband) to adapt to the richness of vibration energy distribution during audiometry, and can be more refined in frequency analysis. At the same time, there is a storage function with 6 channels, which can respectively store signals from 6 frequency bands or measurement values from 6 measurement points.
6. Convenient operation: The engineering plastic chassis and panel are easy to operate, providing clear and extensive information in a simple way, making leak detection and testing work convenient and feasible.
