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 [...]
MTI Instruments Whitepaper: Capacitance Guide for Industrial Applications
Capacitance Guide for Industrial Applications This guide from MTI Instruments explains what you need to know about using electrical capacitance for measurement in industrial applications, including advanced manufacturing. Basic Principles Capacitance is the ratio of the change in an electric charge to the corresponding change in its electrical potential (i.e., voltage). Capacitors, components that that have the “capacity” to store an electric charge, consist of conductive parallel plates that don’t touch or connect with each other. Instead, these metal plates are electrically-separated by air or a layer of insulating material (i.e., the dielectric). MTI’s [...]
GaGe Whitepaper: Use of a PC-Based Digitizer in a Medical Acoustic Microscopy System
Use of a PC-Based Digitzer in a Medical Acoustic Microscopy System By Andrew Dawson, Ph. D-GaGe (a Vitrek brand) Introduction ABSTRACT: Construction of a medical acoustic microscopy system is discussed with focus upon usage of a PC-based high-performance GaGe RazorMax digitizer. Three main aspects of the RazorMax’s operation are addressed: usage of Dynamic Range Expansion (DRE) to maximize the detectability of small ultrasonic echoes, high-speed PCI Express Data Streaming for the fastest scanning speed and usage of GaGe’s Trigger Out signal for efficient and synchronous ultrasonic triggering. Conventional ultrasonic imaging [...]
Pipeline Testing
Pipeline Testing Customer Case The customer wants to test pipelines for corrosion and cracks. They intend to use a small robot which they can send into the pipeline. This robot's purpose is to test the pipe by ultrasound and magnetic field for cracks, corrosion and other damage. The customer is using 2 different types of transducers, one for ultrasound and one for the magnetic field. They are sending a pulse with a magnetic field generator, capturing the received signal, rotating the transducer 1/2 degree and then sending another pulse and capturing signal again. After a complete 360 degree rotation, [...]
GaGe Whitepaper: Ground-Breaking Lightning Study Uses GaGe Razor Express High-Speed Digitizer
Ground-Breaking Lightning Study Uses GaGe Razor Express High-Speed Digitizer By Gerald Allgaier, GaGe (a Vitrek brand) Introduction Razor Express digitizer is an integral part of VHF broadband interferometer designed to investigate high-energy radiation from lightning strikes and multi-stroke positive cloud-to-ground flashes. A doctoral dissertation published in 2022 by Michelle Urbani, a PhD candidate at the Universitat Politècnica de Catalunya BarcelonaTech describes the development of a VHF broadband interferometer to investigate and better understand unsolved lightning phenomena [1]. Very high frequency (VHF) is the International Telecommunication Union (ITU) designation for radio [...]
Plasma Coating of Airplane Parts
Plasma Coating of Airplane Parts Customer Case The customer produces plasma coating for airplane parts. They need to count the number of plasma particles on these parts so that they can adjust the plasma torch to be less or more powerful in order to obtain the required thickness of plasma coating. Using a particle detector, they are able to measure temperature, speed and quantity of particles. These parameters are used as feedback to control the plasma coating process. GaGe Case Solution The customer requires a scope card that has both high-resolution and a fast sampling rate. At the time [...]
Whitepaper: Why Capacitance? Benefits and Applications of Digital Capacitive Sensors
Industry applications illustrate the versatility and benefits of today's digital capacitive sensor technology. The electrical capacitance formed between a capacitance probe and target surface varies as a function of the distance, or gap, between those two surfaces.
Gas Turbine Monitoring
Gas Turbine Monitoring Customer Case A customer who designs and develops turbo-machinery uses automated data-acquisition and reduction routines. The complete system can sequentially scan up to 144 pressures, 40 electrical signals, and 50 temperatures. It can also acquire and analyze dynamic pressure/vibration signals as well as the scanned steady-state data. They do precise pneumatic traversing for high-performance radial-flow stages. Using a computer-controlled data-acquisition system, the detailed internal pressures and temperatures can be acquired and processed. Laboratory data files are generated, which can be directly used to process the impeller-cover static pressure data. The data can also be automatically processed [...]
Avionics Bus Monitoring
Avionics Bus Monitoring Customer Case The requirement is to monitor anomalies on an avionics bus that controls systems aboard spacecrafts. The customer will know typical rise times, and therefore, will look for anomalous high-voltage pulses that may occur due to sunspots or cosmic rays. An A/D card with at least 12-bits of vertical resolution is required to capture anomalous glitches for characterization. The required sampling speed is 50 KHz, on two simultaneous channels that monitor two bus lines. The input signal bandwidth is typically 4 KHz. The customer would like to write his own data acquisition application programs in [...]
