A Temperature Drift Compensation Method for Pulsed Eddy Current Technology

Sensors, 2018
Pulsed eddy current (PEC) technology is another important non-contact nondestructive testing technology for defect detection. However, the temperature drift of the exciting coil has a considerable influence on the precision of PEC testing.

Modelling of pulsed eddy current testing of wall thinning of carbon steel pipes through insulation and cladding [PDF]

, 2014
Conventional eddy current techniques have been used to a great extent for detection of surface breaking defects in conductive materials. Pulsed Eddy Current (PEC) techniques excite the probe’s driving coil with a repetitive broadband pulse, usually a ...

Ion-lithium collision dynamics studied with an in-ring MOTReMi [PDF]

, 2012
We present a novel experimental tool allowing for kinematically complete studies of break-up processes of laser-cooled atoms. This apparatus, the 'MOTReMi', is a combination of a magneto-optical trap (MOT) and a Reaction Microscope (ReMi). Operated in an

Validating Numerical Simulations to Support Experimental Testing of MRI Gradient-Induced Heating of Passive Implants. [PDF]

Magn Reson Med
ABSTRACT Purpose Numerical simulations can be adopted to aid the evaluation of the interaction between switched gradient fields and metallic implants and estimate the possible temperature increase. Anyway, an analysis of the consistency of their prediction with experiments is lacking, differently from what can be found for exposure to radiofrequency ...
