Transducer Selection for High Resolution Applications
High resolution applications do not always require an interferometer. If you want to make accurate measurements in the micron to picometer range, then an MTI Digital Accumeasure D100 HD or D200 system may be what you need. Laser interferometers can sell for more than $15,000 and be difficult to setup. For example, you may have to buy additional optics to guarantee a good return signal since the laser beam must reflect off a mirror surface or precision retro reflector in order for the beam to re-enter the interferometer’s optics at less than a degree of reflection angle. The downsides [...]

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 [...]
Capacitance Sensing for Non-Contact Thickness Measurements of Insulating Materials
Capacitance sensing can be used to make non-contact thickness measurements for most insulating materials. Capacitance sensors are known for their ability to precisely measure the thickness and position of conductive targets, but what’s less known is that these sensors can also measure the thickness of non-conductive materials. Examples include glass, sapphire, and plastics, as well as semi-insulating semiconductor materials such as GaAs and silicon nitride. Analog vs. Digital Technologies MTI Instruments, a global supplier of precision measurement technologies, takes the guesswork out of what used to be a complex measurement for non-conductive materials. MTI's Digital Accumeasure system features a [...]

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 [...]
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 [...]
Digital Accumeasure Gen 3 Reduces Noise and Increases Resolution
MTI Instruments is announcing a third-generation digital capacitance displacement gauge with lower noise and an industry-leading resolution. The Digital Accumeasure DSeries Gen 3 provides up to 0.01% FST linearity and is designed for measuring gap, vibration, and positioning. In both analog and digital systems, noise is an unwanted disturbance that distorts or interferes with a desired electrical signal. MTI’s Digital Accumeasure Gen 3 is a lower-noise amplifier than the Gen 2 and features sub-nanometer resolution for highly-precise measurements. Using state-of-the-art technology, the Digital Accumeasure DSeries Gen 3 converts a highly-reliable capacitive electric field measurement (displacement) directly into a highly-precise [...]
