Blade Tip Clearance
Blade Tip Clearance Power Generation Blade Tip Clearance Tolerances Introduction Blade Tip Clearance Solutions for Turbines, Fans, and Rotating Machinery When it comes to turbines and fans, blade tip clearance — the distance between the tip of the blade and the surrounding case — is one of the most crucial measurements. If the blade tips are too close, thermal expansion or vibration could cause destructive contact. If they’re too far, turbine efficiency and performance suffer. That’s why accurately measuring turbine blade tip clearance, fan blade tip clearance, or any [...]
Tolerances of Armature Gaps
Tolerances of Armature Gaps Power Generation Tolerances Of Armature Gaps Tolerances Description Introduction In large motors and generators, the air gap needed to separate the revolving rotor from the stator should be as small as possible as this reduces the magnetizing power requirement. The gap also needs to be large enough to prevent contact between the two, despite manufacturing tolerances on their dimensions or movement resulting from mechanical deflection or looseness in supporting bearings. The gap should also be uniform; a non-uniform gap causes increased noise and vibration. Since large [...]
New Video from MTI! Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing
Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing This animation demonstrates how Accumeasure with capacitance probes can be used as a solution to measure and control conductive film thickness in a production line where these measurements can be fed back to a controller which adjusts the roller(s) to increase or decrease the gap to keep the film’s thickness within specification. The MTI Instruments Capacitive system has greater than 100 nm resolution and 1um accuracy. This solution is appropriate for measuring the following: EV battery plate thickness Non-woven conductive material thickness Conductive film thickness Roll-to-roll conductive [...]
MTI Case-In-Point: Gap Monitor Keeps Wind Turbines Running
Gap Monitor Keeps Wind Turbines Running System helps operators minimize downtime and protect against catastrophic failure Introduction Wind turbine production has been steadily increasing to meet growing demand for renewable energy. As power outputs and the number of installations climb, maintenance becomes ever more critical. Operators want to minimize downtime and protect against catastrophic failure. The ability to predict when maintenance will be required can go a long way to ensure these goals are met. Challenge A leading manufacturer of wind turbine power generators approached MTI for critical gap monitoring sensors. Specifically, the company wished to monitor [...]
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 [...]
White Paper: Precision Power Analyzers
White Paper All the tools needed to study and optimize virtually any power project in a single instrument Introduction The design of any power conversion system requires the measurement of a large range of electrical parameters that could be made using a lab bench full of instruments. The precision power analyzer pulls all of these measurements into a single instrument replacing meters, oscilloscopes, chart recorders, harmonic analyzers and other devices. This paper will provide a basic overview of the functions and capabilities of high-performance power analyzers. Examples of these functions and how to apply [...]

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 [...]
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 [...]
Capacitance Guide for Industrial Applications
Accumeasure Digital Capacitance System D Series Gen 3 View Product Capacitance Displacement and Gap Measurement Probes View Product Accumeasure Analog Capacitance System View Product Basic Principles of Capacitance Capacitance is defined as the ratio of the change in an electric charge to the corresponding change in its electrical potential (or voltage). Capacitors ; components designed to store electrical charge, consist of conductive parallel plates that are electrically separated by a dielectric material, such as air or an insulating layer. MTI’s technology is built on the principles of parallel plate capacitor measurement. A probe [...]
