Leak detectors


Leaks in vacuum systems can cause considerable damage in sensitive industrial processes. Vacuum pumps may fail or require more frequent service. The output quality can suffer, and losses in energy efficiency can occur. As a result, energy costs and overall operating costs increase drastically.

Our TAPIR leak detectors have been specially designed to avoid all these problems. They can locate and quantify leaks precisely. Thus, improving the output quality, efficiency and reliability of the entire process. In almost every industry, from automotive to oil and gas.

There are different ways to detect leakage with our TAPIR. The so-called spray test, that is suitable for components under vacuum. And the sniffing leak detection for components under pressure. The means of detection is the tracer gas helium or hydrogen.

Both test methods are easy to perform and deliver accurate results, making TAPIR the perfect complement for your vacuum process.

Operating principle

Spray test (components under vacuum)
The so-called spray test is the ideal test method for components under vacuum. This measurement principle has the highest sensitivity of all available methods. Helium or hydrogen is sprayed onto the outer surface of the test object. In case of a leakage, the incoming molecules are drawn in by the integrated turbomolecular vacuum pump of TAPIR together with its backing pump. They finally end up inside an analyzer cell. This cell detects the tracer gas atoms.

Sniffing leak detection (components under pressure)
The sniffing leak detection is the perfect method for components under pressure. A test object is pressurized with helium or hydrogen. A sniffer probe, which is connected to our TAPIR, is then slowly and systematically guided over the object. In the event of a leak, escaping tracer gas atoms are detected. And the leak can be localized precisely.

Benefits of the TAPIR HL series
TAPIR HL are the new leak detectors from Busch. All models have been specially designed for spray and sniffing leak detection in almost all applications. These leak detectors are characterized by their fast response time, short start-up times and accurate measurement results.

TAPIR HL are available in two different versions. In a small, ultra-lightweight portable version with an integrated dry diaphragm vacuum pump. This version is the perfect device for service technicians. It can be operated at any orientation making it the ideal choice for sniffing around large equipment and pipelines.

The multipurpose version includes a high capacity oil-lubricated rotary vane vacuum pump for extremely fast pump-down times. Thanks to its high pumping speed, this version is characterized by quick responses to the selected tracer gas. This detector can be placed, for example, on a bench top. Another possibility is to integrate it permanently into an automated production line.

Both versions are equipped with a detachable control panel including a high definition color display with touchscreen. Thanks to its incorporated magnets, it can also be fixed on metal supports. In the event of a leakage, TAPIR either shows the leakage rate on the display or gives an acoustic signal.

All relevant data is stored on the integrated SD memory card. The data can easily be downloaded and used for documentation and post-processing of the leak test results. The menu is clearly structured and intuitive for the user. All parameter settings can be customized. This allows the users to see only what is important for their specific processes.
