vakuumLecksuchgerät

A vakuumLecksuchgerät, often translated as a vacuum leak detector, is an instrument used to identify and locate leaks in vacuum systems. These systems are critical in a wide range of applications, including industrial processes, scientific research, and medical equipment, where maintaining a specific low-pressure environment is essential.

The principle of operation for most vakuumLecksuchgeräte involves introducing a tracer gas or substance into the system and then using a detector to identify its presence where it escapes through a leak. Common tracer gases include helium or hydrogen. The detector, often a mass spectrometer for helium, is highly sensitive and can pinpoint even very small leaks. Other types of leak detectors might use changes in pressure, flow rate, or visual indicators like bubbles in a liquid medium.

The sensitivity of a vakuumLecksuchgerät is a crucial factor, determining the smallest leak rate it can detect. This is often expressed in units of pressure per unit time, such as millibar-liters per second (mbar L/s). The selection of a specific vakuumLecksuchgerät depends on the type of vacuum system, the required sensitivity, the environment in which it will be used, and the nature of the potential leak. Regular use and calibration of these devices are important for ensuring the integrity and efficiency of vacuum systems.
