Abstract:
1. A system for process measurement, the system comprising: a magnetic field generating system, the magnetic field generating system operable to generate a magnetic field and successively change an orientation of the magnetic field; a magnetic field sensor operably positioned to sense the presence of at least a first orientation of the magnetic field as the magnetic field orientation is changed by the magnetic field generating system, the magnetic field sensor comprising at least two Wiegand-effect conductors operably positioned relative to an associated conductor to each generate an electrical pulse in the associated conductor when the first orientation of the magnetic field is sensed; and a storage device coupled to the magnetic field sensor, the storage device operable to accumulate the electrical pulses generated by the at least two Wiegand-effect conductors sensing the first magnetic field orientation, wherein the electrical pulses from at least two of the Wiegand sensors combine to form a single output pulse signal.
