Fiber Optic Sensor Measures Very Small Movements in Piezo Stacks
MTI Instruments, a global supplier of precision measurement solutions, has released an application note that explains how to measure very small movements in piezo devices that convert mechanical energy into electrical energy. Precision measurement of these dynamic, oscillatory motions is required for the research and development (R&D), testing, and troubleshooting of piezo ceramic materials, advanced ceramics that are used in actuators, sensors, and the power modules of ultrasonic welders. Piezo applications range from automotive sensors and medical devices to engineering projects and consumer products. MTI’s App Note explains how its MTI-2100 Fotonic sensor, when used in conjunction with a [...]
Treadmill Power Glitch Monitoring
Treadmill Power Glitch Monitoring Customer Case A customer develops gym equipment such as treadmills. The requirement is for an inexpensive way to monitor voltage signals for long periods of time. The treadmills are controlled by microprocessors that drive the LED displays. The customer has observed that some units intermittently fail during testing, a condition known as a "glitch" or a "brown-out". A glitch can have many causes, one of which is a weak power supply. The customer needs to capture certain key signals when a glitch occurs. At that stage, based on the captured data, it can be determined [...]

How the Aviation Industry Solves Vibration and Balancing Challenges
The aviation industry spends significant amounts of time and money on problems caused by engine vibration. Imbalance, the most common cause of engine vibration, happens because of bird strikes and other impacts, but also because of natural wear and corrosion that redistribute mass. In turn, out-of-balance parts can result in cabin noise, metal fatigue, and cracked turbine, fan, or compressor components. In the most extreme cases, catastrophic engine failure may result MTI Instruments, a worldwide supplier of precision measurement solutions, makes equipment for monitoring vibration levels and balancing rotors. For maintenance, repair and overhaul (MRO) crews who want to [...]
How to Reduce Inconsistent Wafer Measurements
How to Reduce Inconsistent Wafer Measurements Avoid 5 Common Mistakes That Destroy Wafer Measurement Accuracy You take pride in your work. You’re precise, accurate and depend on the right metrology equipment. Then why are your bare semi-conductor wafer measurements sometimes inconsistent? It may be something you’re doing (or not doing) — without realizing it. MTI Instruments discovered there are five common mistakes that engineers and users make with bare semi-conductor wafers. The “Five Mistakes Made When Taking Semiconductor Wafer Measurements” Tech-Brief details these all-too-typical errors that adversely impact measurements. [...]

Five Common Mistakes with Semiconductor Wafer Measurement
Semiconductor wafer measurement requires a high degree of precision. The right metrology equipment and inspection processes are important, but so is procedural consistency and attention to detail. If you’re not getting the results you want, it’s time to look beyond the measurements. With bare semiconductor wafers, users need to avoid these five common mistakes. Mistake #1 | Turning the Device Off Most users turn on metrology devices only when it’s time to use them. As soon as semiconductor wafer measurement is complete, the devices are turned off. This reduces electricity consumption but also introduces thermal instability that can cause [...]
Capacitance Probes: Five Things You Need to Know
Capacitance probes are non-contact measurement devices with a capacitance sensor inside a protective shell or housing. They use cables and connectors to integrate with amplifiers and are an important part of capacitance measurement systems. By using capacitance, engineers can measure physical parameters such as vibration, pressure, liquid levels, metal contamination, and seismic activity – just to name a few. There’s a lot to know about capacitance probes, but five key facts to understand. Capacitance probes are highly accurate and very stable. They’re better than older devices and competing technologies. They require little calibration and support miniaturization and embedding. They [...]
Capacitance Sensors: Three Things You Need to Know
Capacitance sensors are precision measurement tools for process automation, quality control, and tool automation control. They’re used in a many different industries and are suitable for virtually any application where accuracy is paramount. There’s a lot to know about capacitive sensors (as they’re sometimes called), but engineers need to start with three key questions. What are the parameters to specify when selecting a capacitance sensor? What are factors to consider when embedding a capacitive sensor in an industrial application? What is the future of capacitance-based measurement products? MTI Instruments has been providing U.S.-made capacitance sensor systems for over 50 [...]
How to Implement a Complete Digital Closed Loop Control System
Co-authored by Don Welch, Director of Engineering and Business Development Cory Bufi, Software Engineer Isaac Abbott,Product Innovation Engineer – PBS Group Request Whitepaper Today’s electronic designs often call for reasonably fast and precise positioning of miniature components for process deposition elements such as ink jet nozzles, 3D printing elements etc. And as process control moves from mm positioning to micron to sub-micron positioning it becomes necessary to monitor and control positioning actuators such as piezo flexure stage and voice coil motors. Open loop control of the positioning stage may have been adequate in non-precision applications but piezo electric [...]
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 [...]
