Capacitance Probe Detects Water Contamination in Oiling Systems
Capacitance Probe Detects Water Contamination in Oiling Systems Industrial, Research & Development Capacitance Probe Detection of Water Contamination Metrology, Tolerances Description [Application Note 12218]  The adverse effects of water in oil are well known. Negative consequences include higher viscosity reduced load carrying ability hydrolysis (the formation of acids, sludge, and varnish) foam formation and air entrainment additive depletion corrosion on metal surfaces loss of lubrication film strength leading to increased wear cavitations filter plugging Problem As oil system reliability decreases, maintenance and repair activities increase. Corrective action must be taken [...]
Signal Generator Simulates Eddy Current Probe
Signal Generator Simulates Eddy Current Probe Industrial, Power Generation, Automotive, Power Generation, R& D, Solar Simulation of Eddy Current Probe Gap, Amplitude, Displacement, Positioning, Thickness Description [Application Note 31218] Non-contact eddy current probes can be used to measure the position, or position change, of conductive targets in real time. Typical monitoring applications include shaft runout and/or vibration. Probe setup requires an oscillator demodulator circuit. This circuit converts the probe’s magnetic field readings into output voltages proportional to the gap between probe and target. Portal signal conditioning electronics are then used [...]
Digital Capacitance Sensor Provides Closed-Loop Piezo Positioning Control
Digital Capacitance Sensor Provides Closed-Loop Piezo Positioning Control Consumer Electronics, Industrial Closed-Loop Piezo Positioning Control Positioning, Robot Guide Description [Application Note 40418] 21st century electronic manufacturing requires fast, precise positioning of miniature components. For many assembly lines, process control has moved from mm to micron, or even sub-micron, accuracy. Keeping pace with the demand for greater precision requires piezoelectric positioning actuators and/or voice coil motors with closed-loop feedback control. Challenge Traditionally, analog feedback from capacitance sensors has enabled the closed-loop control of conventional positioning stages. Harnessing the extreme accuracies achievable [...]
Vibration and Balancing Systems: The Spectrum Plot
Vibration and Balancing Systems: The Spectrum Plot Aviation / Aerospace Engine Balancing Vibration Description The Spectrum Plot: Types of Aircraft Vibration One of the least understood features of the PBS series of vibration analyzers is the spectrum function. The spectrum functionality is a more difficult function to understand, but once mastered, technicians can quickly develop an extremely in-depth understanding on what is going on in an engine during a test. Figure 1, below, shows a basic spectrum from the PBS system. On the x-axis is frequency, measured in Hz (per [...]
Closed Loop, Non-woven Conductive Film Thickness Measurement and Control Solution
Closed Loop, Non-woven Conductive Film Thickness Measurement and Control Solution Animation showing a system setup used to measure the thickness of thin conductive films such as electric vehicle (EV) battery electrodes. Description Learn how to measure EV battery plate thickness with MTI's Digital Accumeasure, a high-precision capacitance measurement system with nanometer accuracy and stability. Problem Lithium battery plates for electric vehicles consist of lithium ion compounds applied to either a copper plate substrate (cathode plate) or an aluminum substrate (anode plate). The plates are approximately 100-200 um thick ( .004 [...]
led substrate sapphire thickness
N/A led substrate sapphire thickness Displacement Remember that old acronym, GIGO? Garbage in garbage out, it can apply to raw materials as well as programming. Sapphire wafers need to be of a certain quality to ensure maximum yield. EXCESSIVE TTV, BOW, AND WARP LEAD TO PREMATURE LED FAILURE LED MANUFACTURERS NEED TO INSPECT INCOMING WAFERS. WAFER PRODUCERS ALSO NEED TO CHECK AND CONTROL TTV, BOW AND WARP. The market for sapphire wafers, driven by the growth in LED manufacturing, is booming. While the price has come down significantly since 2011, the size of the wafers [...]
Capacitance Sensors Facilitate 3D IC Construction
Capacitance Sensors Facilitate 3D IC Construction Semiconductor, Research & Development 3D IC Construction Distance, Positioning, Displacement Description [Application Note 70518] To boost device performance, today's semiconductor and microelectronics manufacturers are building three-dimensional integrated circuits featuring vertically-stacked silicon wafers and dies. The rationale is simple. Exploiting the Z-axis avoids the power and footprint penalties associated with two-dimensional processes. Implementing the rationale, however, is not so simple. Going vertical requires coplanar surfaces to make contact with all pins, pads, and pillars. Problem Typically, manufacturers measure the angle and gap between two planes [...]
