Airborne ultrasound technology is revolutionizing various industries and applications, thanks to its remarkable versatility and benefits. This groundbreaking innovation utilizes sound waves to detect, measure, and analyze different elements present in the air. Its potential spans across industrial sectors, healthcare, and various other areas, making it an invaluable tool with boundless opportunities.
The ability to identify concealed defects, achieve precise medical diagnoses, and enhance our daily lives through non-invasive means becomes a reality with airborne ultrasound technology. By tapping into sound waves beyond the limits of human hearing, it unveils a realm of possibilities that were once confined to our imaginations.
In this blog, we will delve into the fundamentals of airborne ultrasound technology and shed light on the advantages it brings to various sectors.
Overview of Airborne Ultrasound Technology
PTI’s Airborne Ultrasound technology is a seal quality inspection test method, capable of non-destructively examining seal quality for defects. It is an ASTM Test Method F3004 and FDA Recognized Standard for seal quality testing. Such tests are mainly conducted to provide enhanced seal quality inspection of pouches, flexible packages and tray seals. Airborne Ultrasound technology ensures in-depth seal quality analyses and is applicable for multiple packaging materials Tyvek, paper, foil, film, aluminium, plastic and poly. According to Oliver Stauffer, CEO of PTI-Packaging Technologies & Inspection, “Ultrasound is one of the only technologies that can tell us what the quality of that physical bonded nature of the seal materials are.
Under this technology, ultrasound waves are passed through the package seal which causes reflections of sound waves. The signal strength is reduced or eliminated in the presence of a leak/defect. Such variations are closely observed to identify the leak. Inability to detect non-leak defects is a common challenge faced by most leak test methods. However, with Airborne Ultrasound technology, users are able to identify various types of seal defects; visible and invisible, leaking and non-leaking, process-related and random.
PTI has redefined seal integrity testing
with its latest improvements in the form of Seal Scan (Offline) and Seal-Sensor (100% online testing). Both these technologies utilize non-contact airborne ultrasonic testing technology. With the advancements in form of Seal Scan and Seal-Sensor, Airborne Ultrasound technology has been proven to be the most effective method for non-destructive seal integrity testing, in both offline laboratory testing for in-depth seal quality analysis and 100% inline testing on the production line.
Benefits of Airborne Ultrasound Technology
- Deterministic seal quality inspection technique that assures quantitative and reliable results
- Applicable for multiple material types and combinations regardless of color, transparency, print, surface finish or porosity.
- Eliminates subjective manual inspection methods.
- Non-destructive, non-subjective, no sample preparation
- Technology can be integrated for 100% online defect detection of the final pouch seal.
