Ultrasonic Nondestructive Evaluation: Engineering and ...
The EMAT driver is quite different from the exciter for a piezoelectric transducer. The objective of an EMAT driver is to pump current through the coil. In general, the driver output resistance will not be equal to the coil resistance so some form of ...

Review of Progress in Quantitative Nondestructive Evaluation
In addition to being physically capable of operating in a high temperature environment, the EMAT has several other features that can be exploited to advantage. By simply changing the direction of the magnetic field used, the transducer can be ...

Heat Exchanger Network Synthesis: Process Optimization ...
The exchanger minimum approach temperature (EMAT) sets the lower limit on the temperature difference that must exist between the hot and cold streams of every exchanger in the network for reasonable sizing. A decrease in EMAT causes ...

Audio Engineer's Reference Book - Halaman 7-8
The in-plane EMAT is often referred to as the 'shear-wave EMAT', and the out-of-plane EMAT as the longitudinal EMAT'. The propagation vector of shear and longitudinal waves need not necessarily be perpendicular to the sample surface.

Direct Rolling and Hot Charging of Strand Cast Billets: ... - Halaman 184
To apply ultrasonics using EMATs, the workpiece must be amenable to inspection with conventional ultrasonic equipment (1 MHz range) with no large voids or inclusions. Variations in surface conditions (undulations, heavy scale, etc.) ...
