The detection principle of pipeline leak detector - Ningbo Lide:

When corrosive perforation and fracture occur in underground gas pipelines, trace gas leaks will inevitably occur and slowly spread in surface ditches, wells, sewers, and other places. When the leak detector sends air containing flammable gases to the sensor through an air pump, the resistance value of the detection element will rapidly change with the gas concentration (the magnitude of the resistance value change is proportional to the gas concentration), and at the same time, output a voltage signal, which is amplified by the circuit and processed by the microcontroller before being sent to the display part, and generate an alarm signal that changes with the concentration.

Ningbo Lide produces various types of buried pipeline leak detectors - gas leak detectors/water leak detectors. Consultation and selection:
