Gastops Ltd., global industry experts in intelligent condition monitoring and predictive maintenance technologies, has announced the delivery of its 20,000th oil debris monitoring sensor to the aerospace industry at this month’s Farnborough International Airshow. The company’s 20,000th aerospace MetalSCAN® sensor was delivered in June 2026 in support of the Pratt & Whitney F135 engine program, which powers all three variants of the F-35 Lightning II aircraft. This milestone represents nearly three decades of production deliveries to the aerospace industry and more than 35 years of technology research, development and collaboration with propulsion-system manufacturers.

MetalSCAN sensors are designed to monitor and detect metallic wear debris within lubricated mechanical systems. The resulting information can provide an early indication of component wear and developing equipment problems, allowing operators to assess machinery condition without relying solely on fixed inspection intervals. By continuously monitoring debris circulating in an oil system, the technology supports condition-based maintenance strategies and more informed maintenance decisions. This can help operators improve asset availability, reduce unnecessary inspections and manage equipment lifecycle costs.

Gastops first began developing its oil debris monitoring technology in the early 1990s for integration into the Pratt & Whitney F119 engine powering the F-22 Raptor. The company delivered its first production unit in 1997. Since then, the technology has been selected for military and commercial aerospace programs and incorporated into several major propulsion platforms. These include the Pratt & Whitney F119 engine for the F-22 Raptor, the F135 engine and LiftFan system for the F-35 Lightning II, the Eurojet EJ200 engine for the Eurofighter Typhoon and the Pratt & Whitney GTF engine family.

“For more than 35 years, our research and innovation, and collaboration with our partners have advanced our condition monitoring technologies that improve the safety, performance, and availability of critical aerospace assets,” said Daniel Obedi, Vice President, Aerospace Platforms at Gastops. “While MetalSCAN remains a core solution in our portfolio, we have also advanced complementary technologies such as ChipCHECK®, expanding the capabilities available to both commercial and defence operators worldwide.”

Gastops has also extended its oil debris monitoring technology beyond aerospace into marine, energy and industrial applications. Across all markets, the company has delivered more than 50,000 MetalSCAN sensors worldwide.
