Abstract: A device is disclosed for measuring Barkhausen noise of a crankshaft to identify defects in the crankshaft while the crankshaft is installed on an engine, comprising: a housing configured to attach to a connecting rod; at least one sensor assembly mounted to the housing including at least one Barkhausen noise sensor; and a spring disposed between the housing and the at least one Barkhausen noise sensor to urge the at least one Barkhausen noise sensor into contact with a pin journal of the crankshaft as the crankshaft rotates.
