PAxx Power Analyzers using External Current Sensors: Application Notes
Current Sensors use two main techniques. A current transformer divides current. So for instance a 100:1 current transformer would see an input of 10A and output 100mA. Note that this technique is only useful for AC current. When using a current transformer you can directly input the current into one of our internal shunts as long as you stay within the current limitations of the input. Notice that current transformers are inductive so they act as a low pass filter. If you use a current transformer it is important to select a transformer that will work accurately at your frequency [...]
MTI Instruments’ Accumeasure HD System Proven to Be Highest Resolution Capacitance System in the World
ALBANY, N.Y., April 9, 2021 /PRNewswire/ — MTI Instruments, Inc. (“MTI Instruments”), a wholly-owned subsidiary of Mechanical Technology, Incorporated, (NASDAQ: MKTY), announced today that its Accumeasure HD system technology has been proven to measure distances as small as 69 picometers, setting a new bar for capacitance systems. The results were recently published in a white paper by Kevin Harding of Optical Metrology Solutions. Harding’s white paper can be accessed on MTI Instruments’ website. Harding’s independent study confirmed the findings of an internal experiment by MTI Instruments that concluded the Accumeasure HD system can provide picometer-level accuracy when used with [...]
TIRE TREAD INSPECTION WITH 1D LASER SENSOR
Tire manufacturers wants to satisfy their customers, and protect themselves from liabilities, manufacturers are moving to 100% tire inspection for defects and abnormalities. Defects not only cause potential safety issues but they can also introduce unwanted vibration into the vehicle suspension system. Belts can be overlapped, or not cover the complete tire surface, causing weak or bubbled areas and imbalances. The tread depth can be too shallow, leading to decreased service life. An uneven tire can cause excessive runout and vibration. MTI was approached by a major manufacturer requesting a solution to measure tread depth, runout and blistering. They [...]

Torque Converter
Industry Automotive Applications Torque Converter Measurement Type Surface Description Since minute defects in the torque converter casing wall thickness can result in unacceptable and dangerous torque converter expansion, a precision measurement system was needed to measure the impeller hub displacement and thus the torque converter axial displacement. An AC dynamometer would be required to spin the torque converter at a high rate of speed while a fast response hydraulic system is needed to pressurize the converter to pressures up to 150 psi. MTI’s MicroTrak laser sensor was selected because it offered [...]
Measuring the Step Height Thickness of Non- Woven Conductive Films
Establishing and maintaining product quality throughout the production process is a common challenge of all manufacturers. How does an organization ensure the optimal output from their production lines, especially in real time? Key to this is strong non-destructive measurement practices that can take place at various points along the production process. The case study below is an example of how this was done at Saint-Gobain to measure the thickness and density of foam materials. They engaged with MTI's team of experts as their current direction was proving cost-prohibitive. Saint-Gobain's R&D organization, led by Dr. Mickael Boinet, found a solution [...]
FIBER OPTIC PROBES MEASURE STATOR BAR VIBRATION
[Application Note 11718] One of the primary concerns in large generator design is vibration. Excessive vibration can lead to premature breakdown of insulation and other materials, ultimately resulting in early failure of the generator itself. The Problem A leading manufacturer of power generating equipment required a sensing system able to measure stator bar vibration in a partial generator mockup. Specifically, the company’s multi-day testing program demanded a sensing system that was immune to the large magnetic field generated by live stator bars capable of withstanding high heat built up from prolonged testing, and compatible with a proprietary stator bar [...]
How Aircraft Operators Reduce Downtime While “Sweating the Assets”
In a recent article called “UPS Gives Old Jets New Life,” Bloomberg reports how United Parcel Service (UPS) is replacing the cockpit computers on its Airbus SE freighters in order to reduce downtime, increase productivity, and avoid large capital expenses. Known as “sweating the assets,” this business strategy is also benefitting the two aviation maintenance repair and overhaul (MRO) organizations that are performing the computer upgrades. “Doing such work,” writes Bloomberg’s Thomas Black, “is a huge potential market.” As the article explains, UPS purchased flight computers for over 50 Airbus A300-600 jets some twenty years ago. However, the memory [...]

With the new credit designation, MTI Instrument's course, "Vibration Analysis and Engine Balancing Using the PBS-4100 System," can earn an eligible individual up to 16 hours of credit towards AMT Awards issued through the FAA [...]
Wafer Backgrinding and Semiconductor Thickness Measurements
Wafer Backgrinding and Thickness Measurements in Semiconductor Manufacturing Wafer backgrinding, also known as wafer thinning or wafer lapping, is a critical step in semiconductor packaging. This process, which involves grinding the backside of a semiconductor wafer, reduces its thickness to enable the stacking of integrated circuits (ICs) and support high-density packaging. The thickness of the wafer plays a crucial role in determining the overall size of the package, an important factor as modern electronics such as smartphones, laptops, and other devices continue to get thinner and more compact. In applications like MEMS (Micro-Electro-Mechanical Systems), the backgrinding process also affects [...]
