Hocking’s new D62s instrument can perform two tests with a bandwidth of 2kHz and our standard surface differential probe (type 5P469) has a 2mm diameter. The 5p469 has been widely used for bearing inspection at .1 mm notch sensitivity. I’ve just checked with a spinning notch on an electric motor and the signal drops to 6 dB at 5 m per second. So by doing the maths if we assume a 2mm scan pitch on a piece of round material 127 mm dia. and 400 mm long (.16 m^2) and use two probes this gives 8 seconds. There is of course no allowance for handling times. You could of course use a wider probe if you were prepared to accept lower sensitivity and double the inspection rate. The difficult part is how do you handle a component safely and accurately.
