Portable Vibration/Balancing System Simplifies Jet Engine Testing
Portable Vibration/Balancing System Simplifies Jet Engine Testing Aviation/Aerospace, Power Generation Jet Engine Testing Amplitude Description [Application Note 32818-2] Overall gas turbine engine vibration may be considered the summation of vibration contributions from various moving parts within the engine. The ability to correlate vibration magnitude with specific moving parts helps engineers ascertain and correct the sources of vibration. Problem Commercial and military aviation rely on vibration analysis and trim balancing to establish such correlations. Vibration analysis detects discrepancies in rotational machine dynamics; trim balancing is used to reduce vibration amplitudes of [...]
Push-Pull Capacitance Sensor Measures Ungrounded Targets
Push-Pull Capacitance Sensor Measures Ungrounded Targets Solar, Semiconductor Measurement of Ungrounded Targets Thickness, Metrology Description [Application Note 50318] Today’s semiconductor and solar industries drive the demand for thinner wafers to conserve silicon and fulfill new IC applications. To meet this demand, wafer fabricators seek greater dimensional control of their silicon products. Non-contacting capacitance sensors offer the precision, accuracy, and speed needed to measure flatness, thickness variation, and other critical dimensions. Typically, the standard capacitance sensor acts as one plate of a classical two-plate capacitive gap measurement scenario. The grounded target [...]
Windshield Manufacturing
Windshield Manufacturing Automotive Windshield Manufacturing Tolerances Description In order to maintain proper profile and thickness within a glass furnace the extrusion plate spacing must be maintained at a predetermined gap. Unfortunately, due to process changes and temperature swings this gap can fluctuate significantly in short periods of time. This variation causes the glass thickness to change (check out our glass thickness measurement devices to accurately measure thickness), producing uneven temperature gradients and creating potentially weak glass panels. To control this critical parameter the manufacturing process requires automated active feedback control [...]

Road Surface Quality
Road Surface Quality Transportation Road Surface Quality Surface Description Introduction Various Departments of Transportation (DOTs), both nationally and internationally, are developing and incorporating automated road quality inspection equipment. “It is well known that the characteristics of the road surface, especially for the surface layer, are essential to satisfy some primary requests, such as user safety and noise pollution. Road performances are being evaluated and classified by the adoption of certain parameters that affect various characteristics of the road, one of which is the surface texture; it is strictly related also [...]

DC Motor / Commutator Bar
DC Motor / Commutator Bar Industrial Dc Motor / Commutator Bar Depth Description Using a MTI Microtrak 4 laser triangulation sensor to measure a DC motor’s armature / commutator bar run out. We fitted a DC motor armature (rotor) in a lathe to spin it. The MTI laser head a DTS 50-20 has 50 mm standoff and a 20 mm measuring range. The laser was placed in a FS-5 magnetic  mount fixture and pointed at the commutator bars. The lathe was spun at 180 RPM and the commutator bar run out [...]
