Leakage testing systems, flow testing devices and turnkey solutions

Dr. Wiesner – since 1968 this name stands for innovation, quality and reliability

No matter if fully automated, partly automated or manual leakage tests – we provide the suitable solution for every application.

As a specialist for leakage testing systems, we know the wishes of our customers who come, for example, from the automotive industry, fittings industry, electrical engineering, aerospace industry or from the medical engineering.

Both the set-up time and the actual testing period of the leakage testing should be extremely short. This often requires a fully automated device for leak testing. In other cases, a test stand for leakage testing, which works according to the cycle frequencies of the preliminary and subsequent working steps, might be the optimal solution. We provide you with the appropriate test equipment and complete systems for high cycle speeds with simple operation and reproducible test results.

As different demands for leak tests require different test methods, we develop the measuring principle and device for leak testing optimally tailored to your application.

We are able to implement the following test methods for leak testing in our testing plant:

• Relative pressure method (with overpressure or vacuum)
• Differential pressure method (with overpressure or vacuum)
• Pressure rise method (with overpressure or vacuum)
• Flow measurements (volume flow)
• Flow test method (mass flow)
• Hydrogen method (snifting test)
• Hydrogen method (integral test)
• Helium leak detection (snifting test)
• Helium leak detection (accumulation method)
• Helium mass spectrometer method (integral test)
