Abstract

The Ferritector model 1581 features a magneto resistor transducer and the active elements comprise a single integrated‐circuit amplifier mounted with other units on a printed circuit board. It measures the ferrite content of stainless steel with particular reference to the control of weld quality and possible degradation of neighbouring regions. It is check calibrated with plastic films interposed between the probe tip and a mild steel reference plate.
