How to Measure Dielectric Separator Thickness in EV Batteries
The International Energy Agency predicts that as many as 125 million electric vehicles (EVs) will be on the road by 2030. At the heart of these electric cars, trucks, and buses is the lithium-ion (Li-ion) battery, a type of rechargeable battery with high energy density and low self-discharge. The plates in Li-ion batteries consist of lithium compounds that are applied to either a copper plate substrate (cathode) or an aluminum substrate (anode). In turn, these two plates are separated by a dielectric separator. All of the layers in an EV battery are extremely thin. In fact, the cathode and [...]
Modernizing a Passive Sonar that has a Beam-Former with Digital Output
Modernizing a Passive Sonar that has a Beam-Former with Digital Output Customer Case The customer's requirement is to capture 10 signals, lasting 0.6 milliseconds each. 120 such signals arrive sequentially from a multiplexer within a beam-former. The clock rate is 2 MHz. The beam-former creates 120 beams and the raw digital data (underwater acoustic signal) from each beam is present at the output port of beam-former with a clock rate of 2 Mhz. At a certain time, we get the digital raw data of one beam. We plan to get 120 x 10 12-bit data records. That is, we [...]
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 [...]
SEPTA Case Study: Major Metropolitan Transit System Uses Vitrek Power Analyzer to Monitor High-Power DC Feeders
- - - Challenges Personnel needed a reliable, portable instrument to accurately measure and record the current on each feeder over a selected time period. - Overview The Southeastern Pennsylvania Transportation Authority (SEPTA) operates the transit system throughout the city of Philadelphia, extending into the surrounding counties in Pennsylvania and across the Delaware River into New Jersey. A major component of this system is the network of subways and commuter trains. Power for the operation of these trains is provided by an array of substations distributed throughout the region. One [...]

Capacitance Sensing Provides Two Ways to Measure EV Battery Plate Thickness
MTI Instruments has released an application note that explains how to use capacitance to measure the thickness of the lithium battery plates in electric vehicles (EVs). Manufacturers need to check these plates for thickness before calendaring them together to ensure that the overall battery diameter is within specifications. In EV batteries, lithium ion compounds are applied to either a copper plate substrate (cathode) or an aluminum substrate (anode plate). These conductive plates are separated by a dielectric. MTI Instruments, a global supplier of precision measurement solutions, makes capacitance sensors that can measure thicknesses materials down to nanometers. Moreover, MTI [...]
Synchronizing Over A Wide Sampling Speed Range
Synchronizing Over A Wide Sampling Speed Range Customer Case The client has set up an experiment where he needs to generate a stimulus signal and apply it to a He-Ne Laser with some polarizing optics. The response signal is a measurement of the Faraday effect. The signal is noisy and requires averaging over a very long time. The stimulus and response must be synchronized over a wide frequency range. For synchronization, the application requires a wide band of sampling speed from, 1 KS/s to 50 MS/s. GaGe Case Solution While GaGe's CompuScope 14100 provides the required digitizer performance, it [...]

White Paper: Cable & Connector Test System Facilitates Multi-Point High Voltage/Current Testing
White Paper: Cable & Connector Test System Facilitates Multi-Point High Voltage/Current Testing Introduction Hipot testing is critical in assuring compliance with a host of electrical safety standards and in confirming the assembled product is free from electrical or mechanical defects. Hipot testers are used to measure leakage current and insulation resistance between all components and connections, confirm solid ground connections and test ground bonds. All of these tests require the sequential application of precise and controlled high voltages or currents between pairs of elements then accurately measuring and recording the results. Products like the Vitrek 95x and V7X series [...]

How Aviation MROs Can Maximize Labor Efficiency and Asset Uptime
MTI Instruments is supplying the aviation industry with solutions to the skilled labor shortage and reduced equipment availability. No, our Albany, New York company isn’t providing aviation MROs with more flight line personnel, engine mechanics, or Boeing 737 MAX aircraft. Instead, we’re delivering precision measurement solutions that can help MROs to maximize labor productivity and asset uptime. Solving the Skilled Labor Shortage Aviation MROs have a choice. They can wait for training programs to provide new workers, poach workers from competitors, invest in robots, or look for ways to gain greater efficiency from existing labor assets. About 18 months [...]
Time Resolved Spectroscopy of Protein Crystals
Time Resolved Spectroscopy of Protein Crystals Customer Case The customer is involved in Time Resolved Spectroscopy of protein crystals. This involves shooting a laser onto the protein crystals and measuring the pulses generated by the crystals (as they are projected out of the sample) and their decay over time. Due to the very noisy nature of the return signals, it is essential to average many pulses in order to recover the pulse shape and measure the decay. The decay takes place over many tens of milliseconds, so it is necessary to acquire very long records (in the order of [...]
Hyper Remote Laser Sensor
Hyper Remote Laser Sensor Customer Case The customer is at the prototype stage for building a hyper remote sensor which will fly over the ocean and be able to see 100 to 200 feet below the surface. The sensor is being designed in order to determine the composition of the ocean and the ocean floor. This remote sensor will be extremely useful in the detection of pollution and studying the way pollution is being distributed by ocean currents. It will also be useful to the military (navy) for creating mine-finding systems. A deep blue laser will be used to [...]
