EMAR EMAT Pipe Wall Thinning Signal Processing Thickness Measurement
Electromagnetic acoustic transducer (EMAT) provides non-contacting measurements and is often applied to monitoring in gh temperature environment. One of drawbacks of EMAT is its low sensitivity and S/N ratio. One way to overcome the uwback is to introduce an Electromagnetic acoustic resonance meth od (EMAR); it has a high capability of evaluating ckness or ultrasonic velocity, and it is applied to the measurement of thickness, elastic constants, damping propertiesso on. Since the principle of the method is...
