There are some instances where an acceptable leak rate is so small as to be practically zero. Few air leak test methods, such as pressure decay, have the necessary detection range. These situations call for a trace gas-based test method. Learn more in this article in Quality Magazine, written by Cincinnati Test Systems' Systems Engineer, Peter Bonyhati.
Helium leak testing is one of the oldest and most developed members of the family of trace-gas-based leak testing methods. This article in Quality Magazine by Cincinnati Test Systems' systems engineer, Peter Bonyhati, provides an overview of uses and benefits of the various trace gas methods; helium and its alternatives.
A poor seal between the part to be tested and the leak test station can skew test results, allowing faulty parts to pass and perfectly good ones to be failed. In this feature published by Automation.com, Sciemetric leak test specialist Robert Plumridge explores how quality engineers can address the common issues with achieving a consistently reliable seal to ensure a reliable test.
Sciemetric CEO Nathan Sheaff talks to the editors of Smart Industry about how digital transformation and big data analysis have converged to create a new generation of intelligent leak test systems that provide manufacturers with the reliability and the repeatability to achieve a higher standard of production quality.
Sciemetric’s sigPOD is featured by the editors of Assembly Magazine as part of a roundup on the latest leak test systems on the market from a number of competing vendors.
In this feature with Quality Magazine, Rob Plumridge, Sciemetric leak application engineer, discusses how to tackle the first “R” of Gage R&R for leak testing – repeatability. By focusing on repeatability first (before the other “R” – reproducibility), manufacturers can be certain they have addressed all the controllable variables that can impact the leak test, regardless of the equipment.
Through the adoption of new leak testing approaches that provide comprehensive data about the entire leak test cycle, manufacturers can get more out of their leak test. Use of process signature technology that provides comprehensive data about the leak test offers manufacturers significant benefits that impact the bottom line. Investment in modern leak test technology delivers a quick ROI, supports compliance initiatives, improves productivity and ultimately, improves product quality.
Richard Brine, Sciemetric’s CTO, talks to the editors of New Equipment Digest about the 3520 Series Leak Test and how its use of smart sensors, precision electronics and digital process signature analysis delivers a new level of repeatability and reliability to the often frustrating process of leak testing.
The editors of Design Engineering profile Sciemetric’s Model 3675, a turnkey station to boost the speed and accuracy of leak testing. The 3675 can combine up to three of Sciemetric’s 3520 Series Leak Test units in one stand, controlled by a single sigPOD controller.
Sciemetric product launch manager Robert Ouellette shares with Quality Magazine how quality engineers can measure and compensate for the sometimes dramatic effects of temperature variations on the accuracy and repeatability of a leak test.
