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 second). [...]

Thickness Information of Composite Materials
Thickness Information of Composite Materials Industrial Thickness Information Of Composite Materials Thickness Description Introduction: Composite materials consist of two or more materials which include a substrate or base material such as paper, cotton cloth, or glass cloth along with a resin or adhesive such as epoxy, melamine, or silicone. To make a thermoset laminate, the base material is coated with the adhesive so that layers of material can be pressed under heat and pressure into sheet form. The Problem: Composite material thickness needed to be verified prior to forming or [...]

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 [...]

Arbitrary Ultrasonic Generator
Arbitrary Ultrasonic Generator Customer Case Ultrasonic generation pulses must be varied to accommodate different types of ultrasonic transducers. General-purpose highly damped contact transducers are usually excited by a wideband, spike-like pulse that is provided by many common pulser/receiver units. Lightly damped transducers, used for example in high power generation, require a narrowband tone-burst excitation from a separate generator unit. Sometimes, even the same transducer will be excited differently, for instance, to study the dispersion of a material's ultrasonic attenuation or to characterize ultrasonic transducers. In order to construct a flexible ultrasonic generation unit, engineers have excited transducers with a [...]
