  • Industrial Leak Detection Systems | Gas Leak Detection

    During routine testing for leaks, a component is placed in a pressurized chamber that is then filled with traceable gas or air. If there is a leak, it will cause the gas to move from a high pressure to a low pressure and generates a turbulent flow that is sensed by the gas leak detection equipment. This type of routine testing is widely used for industrial applications to ensure a sound structure in critical

    This is certainly the case with leak detection, with four main methods being employed: the bubble test; pressure decay test; pressure rise test; and helium sniffer mode/helium vacuum mode tests. These four tests roughly correspond to the “simplistic” bubble test (for low-vacuum pressures), through to the “high-tech” helium tests (for high-vacuum pressures).
