Gap Monitor Keeps Wind Turbines Running
Gap Monitor Keeps Wind Turbines Running Power Generation Wind Turbine Gap Monitoring Distance, Gap, Tolerance Description [Application Note 21218] 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. Gap monitoring sensors from MTI Instruments help wind turbine operators predict impending [...]
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 [...]
Ultrasonic Tissue Characterization
Ultrasonic Tissue Characterization Customer Case This customer's application is Ultrasonic Tissue Characterization. Their ultrasonic sensors transmit 16 signals. The customer's requirement is to capture 512 points on the 16 channels, average them together, and then store the data in a buffer, with the system running continuously. They would like to be able to update the average buffer and recapture data as fast as possible. They would then like to log the data to disk or process the data and display an image on the screen. Since the signals coming in from their ultrasonic sensors are very weak, the customer [...]
Digitizing Ultrasonic Signals
Digitizing Ultrasonic Signals Customer Case The customer has an ultrasonic signal that he wants to digitize with either 8 or 12-bit resolution. The sampling rate required for this application is a minimum of 16 MSPS (20 MSPS is acceptable). Finally, the data must be acquired for a full 10 seconds. The data is not coming in continuously: it is arriving in bursts one millisecond apart (PRF = 1 KHz). For each trigger the customer wants to capture approximately 200 us of data. Once this data is acquired, the customer wants it saved to the hard drive as a standard [...]
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 [...]
