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 [...]

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 [...]
Measurements with Capacitance Gage for Sub-Nanometer Thermal Expansion Characterization
MTI Instruments contracted an independent Metrology expert to test and verify the performance of a new high resolution capacitance gauge. The Accumeasure HD has passed in house testing where its performance was tested against a commercial laser interferometer (See Application Note). Optical Metrology Solutions (OMS) was chosen based on their extensive experience and proximity to MTI’s manufacturing plant. OMS was tasked with designing a challenging experiment to verify the accuracy and resolution of the MTI Accumeasure HD capacitance system that could also be encountered in a typical customer application. Their experiment explored the ability to measure sub-nonometer thermal expansion [...]
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 [...]
MTI Instruments’ PBS-4100+ Series Training Eligible for FAA Training Credit
MTI Instruments' PBS-4100+ Series Training Now Eligible for Credit Under William (Bill) O'Brien Aviation Maintenance Technician (AMT) Awards Program ALBANY, N.Y., Feb. 23, 2021 /PRNewswire/ -- MTI Instruments, Inc. (MTI Instruments), a wholly-owned subsidiary of Mechanical Technology, Incorporated (OTCQB:MKTY), today announced that its training course on the PBS-4100+ engine vibration measurement and balancing system is now credit-eligible under the Federal Aviation Administration's (FAA's) William (Bill) O'Brien Aviation Maintenance Technician (AMT) Awards Program. 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 [...]
MTI’s Accumeasure HD Amplifier vs. Laser Interferometer
Achieving high resolution and accuracy for very small displacement measurements is generally an expensive and complex undertaking. The typical instrument of choice for achieving the accuracy required (picometer resolution with nanometer accuracy) is a laser interferometer. However, MTI Instruments Accumeasure D200HD Amplifier provides exceptional accuracy and stability while coming in at significant cost savings with ease of use. We decided to pit the AccumeasureHD vs a Laser Interferometer and compare results. Specifically, this comparison focuses on minimum expected resolution and the effects of noise on accuracy. Micro positioning applications include measuring the mask height of semiconductor wafers during lithography. The [...]
Neutrinos Study
Neutrinos Study Customer Case Neutrinos are said to be the most elusive and exotic particles in the universe. They are tiny neutral elementary particles that interact with matter via the weak nuclear force. Scientists are still trying to measure the mass and to characterize their properties. A customer who is studying neutrinos will be using photo multiplier tubes (PMT) coupled to a scintillating material to detect them. The PMT will produce a small electrical pulse when a neutrino is detected. These PMTs are located 2 Kilometers deep, in a mine located in Ontario, Canada. The customer is looking for [...]
