Zusammenfassung:A spin sensor includes a fuze housing, a sense weight and a rotating induction device. The rotating induction device comprises a first rotatable element affixed to the fuze housing and a second rotatable element affixed to the sense weight. The second rotatable element is mechanically coupled to the first rotatable element such that it may rotate relative to the first rotatable element. In addition, the second rotatable element is inductively coupled to the first rotatable element such that the relative rotation between the first rotatable element and the second rotatable element generates a spin signal on an electrical connection to the rotating induction device. The spin signal may be compared to a suitable spin profile to determine if a valid spin environment is present.
