Measurements Using Capacitive Sensors
Precise Measurements Using Capacitive Sensors Capacitive sensors can be divided into two categories based upon their performance and intended use. High resolution sensors are typically used in displacement and position monitoring applications where high accuracy, stability and low temperature drift are required. Quite frequently these sensors are used in process monitoring and closed-loop feedback control systems. Proximity type capacitive sensors are much less expensive and are typically used to detect the presence of a part or used in counting applications. Applications Position Sensing General positioning is probably the most [...]
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 [...]
3D Integrated Circuits Use Capacitive Sensing to Ensure Coplanarity
Three-dimensional (3D) integrated circuits (ICs) feature silicon wafers and dies that are stacked vertically for improved device performance. By using the Z-axis, 3D ICs can overcome the power and footprint limitations associated with two-dimensional (2D) integrated circuits. Yet 3D ICs need coplanar surfaces to contact all of the pads, pins, and pillars. To determine coplanarity, semiconductor manufacturers measure the angle and gap between two planes. Bonding tool actuators use these measurements to adjust components and ensure that all device pins and solder balls reside on the same geometric plane. This process, active parallelism compensation, promotes proper bonding without residual [...]
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 [...]
The Top Five Trends Impacting Test and Measurement for 2019
With 2019 upon us, we know everyone is thinking about what's next in the Test and Measurement industry. We also know that without test and measurement equipment, engineers can't accurately and consistently prove that their mechanical or electronic devices perform as required. When they don't work, engineers also need to determine why and how to fix them. All of this leads to innovative thinking on how to test and measure even better by taking advantage of rapidly growing trends such as digitization, software, additive manufacturing, the Internet of Things (IoT), and new sensing applications that are driving advances in T&M. [...]
Offshore Wind Supply Chain Uses MTI Capacitance Sensors
Capacitance sensors from MTI Instruments are an important part of the supply chain for offshore wind (OSW) in New York State. According to a recent report from the Center for Economic Growth (CEG), New York’s Capital Region is home to MTI Instruments and dozens of other manufacturers who support this growing form of wind power. The Capital Region also offers essential infrastructure for OSW. As the CEG report explains, the New York State Energy Research Development Authority (NYSERDA) has assessed 54 waterfront sites for OSW-related projects such as component staging, manufacturing, and fabrication. Two of the most promising sites [...]

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 [...]

New Signal Buffer Conditioner Solves Signal Distribution Challenge
MTI Instruments is solving signal distribution challenges with a new product, the BC804 signal buffer conditioner. Now available as part of a limited production run, the BC804 acts as a buffered amplifier and is optimized for ultra-sensitive measurement equipment. When a single signal must be distributed to multiple instruments, one shortened output can affect the others. The BC804 solves this signal-distribution challenge by providing eight fully independent and isolated buffer amplifier channels. With the BC804, each channel has one input and four buffered outputs. Each output can tolerate a short without failure and won’t affect the other outputs. Equipped with [...]
