LD-HQ01The handheld intelligent digital leak detector is an underground pipeline leak detector produced by Ningbo Zhenhai Lide Instrument Equipment Co., Ltd. It is characterized by being small and portable, and can be detected by hand.

Can detect leaks in various types of pressure pipelines such as water, oil, and gas, including steel, cast iron, and othersPVCCement pipes and asbestos pipes, etc. The principle is that when various pressurized pipelines such as water, oil, and gas are damaged and leaked, the pressurized water, oil, and gas are sprayed outward from the damaged part of the pipeline, and the friction between them and the crack of the pipeline produces vibration, which will cause injection noise. This sound is transmitted along the pipeline to both sides and the road surface above the buried ground. At this timeLD-HQ01The sensor of the leak detector detects this weak leak signal above the road surface, amplifies and displays it through the host, and selectively filters out noise to independently produce leak sound waves, allowing the operator to find the leak source.

LD-HQ01It is a leak detection instrument that uses a low-power microprocessor and filter to digitize the leakage vibration signal. It uses a specially designed high-sensitivity broadband vibration sensor, which is amplified and digitally filtered to display two types of images on the LCD screen. Based on the characteristic that leakage vibration is a continuous signal, it is adopted in digital processing6The method of cyclic detection in multiple frequency bands generates6Display a straight column and suppress sudden impact interference (not displayed). In response to the superposition of external interference and leakage signals, the Z-small value method is adopted within the sampling time window, and the corresponding numerical display is provided. Z maximizes the suppression of external interference.
