New Directions in Eddy Current Sensing
Eddy current testing is an effective way of detecting fatigue cracks and corrosion in conductive materials. The cost of using the technology is low, and the devices can monitor subsurface defects and defects under insulating coatings without touching the surface of the specimen. Although this technique is applicable for many tasks, the aircraft and nuclear power industries are the primary users...
متن کاملEddy-current non-inertial displacement sensing for underwater infrasound measurements.
A non-inertial sensing approach for an Acoustic Vector Sensor (AVS), which utilizes eddy-current displacement sensors and operates well at Ultra-Low Frequencies (ULF), is described here. In the past, most ULF measurements (from mHertz to approximately 10 Hertz) have been conducted using heavy geophones or seismometers that must be installed on the seafloor; these sensors are not suitable for wa...
متن کاملPulsed Eddy Current Sensing for Critical Pipe Condition Assessment
Pulsed Eddy Current (PEC) sensing is used for Non-Destructive Evaluation (NDE) of the structural integrity of metallic structures in the aircraft, railway, oil and gas sectors. Urban water utilities also have extensive large ferromagnetic structures in the form of critical pressure pipe systems made of grey cast iron, ductile cast iron and mild steel. The associated material properties render N...
متن کاملAn Ink-Jet Printed Eddy Current Position Sensor
An eddy current sensor with an ink-jet printed flexible inductor has been designed and fabricated. The inductor has been designed by means of software developed in-house. It has been fabricated by ink-jet printing with silver ink on a flexible substrate. The inductor is a part of the oscillator circuit whose oscillating frequency is measured by a microcontroller. The sensor characteristics have...
متن کاملEddy Current System for Material Inspection and Flaw Visualization
Eddy current methods have been successfully used in a variety of non-destructive evaluation applications including detection of cracks, measurements of material thickness, determining metal thinning due to corrosion, measurements of coating thickness, determining electrical conductivity, identification of materials, and detection of corrosion in heat exchanger tubes. This paper describes the de...
