Problems with fuel or water can be very serious in the aeronautical, aerospace and airship industries. A component made from one material may be perfect for containing liquid water or hydrocarbons, but can allow their vaporous to pass through virtually unchecked. Not only can this compromise safety but it can damage the electronics, navigation or power systems in a craft, missile or drone. Versaperm says it can measure this effect (permeability) across an exceptionally wide range of temperatures and pressures for just about every liquid, vapour material and component used in the industry.
Conventional tests on materials, tanks, pipes, seals and components have been laboriously slow and expensive, even under room temperature conditions they can take days, weeks or even months - and produce results that are often neither accurate nor consistent. To overcome this, Versaperm produces a fully customisable version of its analytical vapour permeability measurement system which can employ sensors based on numerous different physical principles to suit almost any application.
The company says the system is simple to use, fast, precise and requires little or no re-calibration. Some results can be produced in as little as 30 minutes and accuracy is in the Parts Per Million (PPM) range for most commonly used materials and gasses (PPB in some cases).
Versaperm also offers a laboratory testing service and technical consultancy for companies that test too few samples to make the purchase of equipment viable.
