Engine Balancing in the Digital Age: Unlocking Faster, Smarter MRO with Integrated Aircraft Data
Introduction Modern aircraft engines generate vast amounts of operational data, yet much of this information has historically remained under utilized during maintenance procedures like vibration balancing. As fleets transition to digitally connected avionics architectures, MRO teams are rethinking how they access and apply engine data to improve efficiency and accuracy. By leveraging direct integration with onboard data networks, today’s vibration balancing systems can streamline setup, reduce dependency on external instrumentation, and deliver faster, more reliable results—ultimately helping operators minimize downtime and maintain peak engine performance. The Role of Engine Vibration Balancing MRO Jet engines operate under extreme mechanical stress, [...]
Brake Rotors Thickness Variation
Industry Automotive Applications Brake Rotors Thickness Variation Measurement Type Surface Description Driving cross country or cross town, we give little thought to the operation or complexity of our vehicle braking systems. They only cross our mind when we absolutely need them; we never stop to think about the extensive design and testing that makes them such a lifesaver. Take the brake rotor for example. Under normal operating conditions it’s subjected to extreme temperatures and forces, which can cause rotor distortion and potential failure. To make certain it can withstand [...]
Understanding Semiconductor Wafer Stress: A Practical Guide to Thin-Film Stress, Wafer Curvature Measurement & Process Control
Introduction Every semiconductor device begins with a nearly perfect wafer. Yet throughout fabrication, that wafer is repeatedly transformed by dozens of manufacturing processes including thin-film deposition, oxidation, implantation, annealing, polishing, and packaging. While each process is designed to modify the electrical properties of the device, it also alters something far less visible—its mechanical condition. The addition of every thin film introduces internal mechanical forces that can subtly change the shape of the wafer. These changes, often measured in only a few micrometers across a 200 mm or 300 mm substrate, may appear insignificant. However, as semiconductor devices continue to [...]
Oil Film Thickness Measurement
Industry Automotive Applications Oil Film Measurement Type Level Description A top marine engine manufacturer commissioned MTI Instruments to design and manufacture a non-contact sensor to measure the microscopic oil film layer between the engine cylinder wall and the piston ring. Engine testing is normally performed through a range of low RPM’s to high RPM’s (400- 6000) with piston linear speeds approaching 500 inches/second and at various torques. A measuring system with high frequency response and small sensor size was essential to keep engine machining to a minimum while not altering [...]

Application Note: Replace Three Legacy Systems with One: Modernizing Aerospace/Defense Test Cells with PBS eXpress
Introduction Many military/defense and commercial aerospace test cells still rely on aging analog instruments that, while functional, introduces risk through calibration challenges, legacy components, and lack of digital data access. As testing demands evolve, the industry is moving toward compact, digital platforms that simplify workflows and improve data usability. A Vitrek customer faced this challenge across multiple engine test cells. Their solution: replace two legacy systems with a single PBS eXpress R+, enabling faster setup, digital data acquisition, and automated reporting. The Challenge The customer’s test cells were built around a mix of aging instrumentation, including TrigTek tracking filters, [...]
Application Note: Why Charge Amplifiers Remain Essential in Aerospace Test Systems
Introduction Many aerospace test programs rely on charge-output piezoelectric accelerometers, force sensors, and dynamic pressure transducers because of their wide frequency response, rugged construction, and ability to capture rapidly changing events. These sensors generate extremely small electrical charge signals—often measured in picocoulombs (pC)—that are susceptible to cable capacitance effects, electrical noise, leakage currents, and environmental influences that can compromise measurement accuracy. Charge amplifiers address these challenges by converting the sensor’s high-impedance charge output into a stable, low impedance voltage signal suitable for transmission, recording, and analysis. By making measurements largely independent of cable capacitance while maintaining low noise, stable [...]

Application Note: Accessing Digital Engine Data for Multi-Platform Aircraft Balancing with MTI PBS Systems
Introduction Modern aircraft engines are no longer dependent solely on discrete analog sensors for critical performance data. Increasingly, vibration amplitudes, phase information, and engine speed are transmitted digitally through aircraft data buses such as ARINC 429 and ARINC 664 Part 7 (AFDX). Yet in many MRO environments, balancing systems continue to rely on accelerometers and tachometer pickups—introducing additional setup time, cabling complexity, and potential variability in measurements. This disconnect between available digital data and traditional measurement approaches creates inefficiencies, particularly for facilities servicing multiple aircraft platforms. For organizations supporting a diverse fleet, the opportunity is clear: leverage the aircraft’s [...]
