Measuring Brake Rotor Thickness Variation with Capacitive Sensing
Brake rotor thickness variation, or disc thickness variation (DTV), causes uneven wear to brake rotors, disc-shaped automotive parts that are squeezed between brake pads to slow or stop a vehicle’s wheels. When a brake rotor has areas of different thickness, the amount of clamping force that’s applied across the rotor’s surface varies. These differences in clamping force lead to difference in torque, and the results may include brake shuddering, pulsating, or vibration. Even under normal driving conditions, brake rotors are subjected to extreme conditions that can cause performance-related issues. To ensure that brake rotors can perform [...]

Capacitive Displacement Sensors: Working Principle & Precision Measurement Applications Capacitive displacement sensors are precision non-contact measurement devices that utilize capacitance changes to determine position, distance, and thickness with exceptional accuracy. These capacitive distance sensors offer superior performance in applications requiring high-resolution measurements, making them essential tools across manufacturing, automation, and research industries. How Capacitive Displacement Sensors Work Capacitive Sensor Working Principle Capacitive displacement sensors operate on the fundamental principle of measuring capacitance variations between two conductive surfaces. The sensor probe acts as one plate of a parallel plate capacitor, while the [...]
Aircraft Engine Test Cell is World’s Largest
The world’s largest aircraft engine test cell is in Atlanta, Georgia (USA), home of the upcoming MRO Americas 2019 show for the commercial air-transport maintenance, repair and overhaul (MRO) industry. Delta TechOps, a division of Delta Airlines and a full-service MRO, recently opened a $100 million test cell at its Atlanta facility that’s capable of running a jet engine at 150,000 lb. thrust. That’s more thrust than the GE Aviation GE90 engine, which powers Delta’s Boeing 777-200 LR fleet, can produce.“This test cell is a vote of confidence in Delta TechOps,” said Ed Bastian, Delta Airlines CEO, in an article [...]

Proforma 300i SA Video Shows Semiconductor Metrology
MTI Instruments, a worldwide leader in precision measurement solutions, has released a YouTube video that shows how its Proforma™ 300i SA semi-automated measurement tool measures silicon carbide wafers for semiconductors. George Relan, MTI’s Global Director of Sales, demonstrates how the desktop metrology system provides non-contact full wafer scanning and 3D mapping of measurement features such as thickness and shape. MTI’s video also shows how the Proforma 300i SA interfaces with an external computer and provides powerful Windows-based software for analysis and reporting. By utilizing MTI push/pull technology, the Proforma 300i SA doesn’t require the semiconductor wafers to have a [...]
MRO Americas 2019: Engine Vibration Analysis from MTI Instruments (Booth #2301)
MTI Instruments, a U.S.-based manufacturer of engine vibration analysis and balancing systems, will exhibit at MRO Americas 2019 from April 9 to 11 at the Georgia World Congress Center in Atlanta, Georgia (USA). Visit MTI Instruments in Booth #2301 at MRO Americas, the premiere event for the commercial air-transport maintenance, repair and overhaul (MRO) industry, to see its PBS-4100 line of vibration and balancing systems. MTI instruments will also give away a 1501A precision signal/function generator. Aircraft engine vibrations caused by out-of-balance parts can lead to cracked fan, turbine, and compressor components. Imbalance-induced vibrations can also cause metal fatigue [...]

Navy Orders Avionics Test and Measurement Systems
The U.S. Navy wants new avionics test and measurement systems. Under the terms of a $109-million award, the Naval Air Warfare Center Aircraft Division in Lakehurst, New Jersey will buy 41 electronic consolidated automated support systems (eCASS) from Lockheed Martin. This test and measurement equipment helps soldiers and Marines troubleshoot and repair aviation electronics while at sea. Avionics, the electronics used in aircraft, support essential navigation and communications functions. With military aircraft, avionics typically include electro-optical, infrared, and other types of sensors for airborne radar, weapons systems, and heads-up displays. Military avionics also need to support electronic warfare systems, [...]
Fiber Optic Sensors Help Stop Subway Shutdown
Fiber optic sensors will help keep commuters moving between Manhattan and Brooklyn this year and beyond. Recently, New York Governor Andrew Cuomo announced that New York City’s Metropolitan Transit Authority (MTA) would not close the L train tunnel for a planned 15-month repair project. Instead, the MTA will use technology-driven solutions to keep the tunnel open and operational for weekday riders. In a joint statement, a panel that included engineering experts from Columbia and Cornell explained that "The L Train Tunnel project gives us the opportunity to integrate technologies and methods that have never been used before in a [...]

3D Integrated Circuits Use Capacitive Sensing to Ensure Coplanarity
Three-dimensional (3D) integrated circuits (ICs) feature silicon wafers and dies that are stacked vertically for improved device performance. By using the Z-axis, 3D ICs can overcome the power and footprint limitations associated with two-dimensional (2D) integrated circuits. Yet 3D ICs need coplanar surfaces to contact all of the pads, pins, and pillars. To determine coplanarity, semiconductor manufacturers measure the angle and gap between two planes. Bonding tool actuators use these measurements to adjust components and ensure that all device pins and solder balls reside on the same geometric plane. This process, active parallelism compensation, promotes proper bonding without residual [...]
Oiling System Uses Capacitive Sensing to Detect Water Contamination
Water contamination can reduce the life of lubricants and increase the frequency of maintenance and repairs. If corrective action isn’t taken before an out-of-limit incident occurs, operational costs can escalate. When unplanned maintenance disrupts operations, productivity suffers and technicians may focus on a quick fix instead of the root cause. To detect water contamination in oil systems, in-line capacitance probes can be used. These flexible, off-the-shelf devices provide automatic and continuous monitoring. Yet checking moisture levels isn’t just about enhancing reliability or eliminating corrosion. In-line capacitance probes improve operations by supporting a proactive approach to maintenance. How In-Line Capacitance [...]
The Top Five Trends Impacting Test and Measurement for 2019
With 2019 upon us, we know everyone is thinking about what's next in the Test and Measurement industry. We also know that without test and measurement equipment, engineers can't accurately and consistently prove that their mechanical or electronic devices perform as required. When they don't work, engineers also need to determine why and how to fix them. All of this leads to innovative thinking on how to test and measure even better by taking advantage of rapidly growing trends such as digitization, software, additive manufacturing, the Internet of Things (IoT), and new sensing applications that are driving advances in T&M.
