Title
(EN) SYSTEM AND METHOD FOR PROCESS MEASUREMENT
(FR) SYSTEME ET PROCEDE DE MESURE DE PROCESSUS
Abstract
(EN)
Process measurement may be achieved by systems and techniques generating output signals based on the measured process. In certain implementations, process measurement systems and techniques may include the ability to generate a magnetic field (504) and successively change the orientation of the magnetic field (508). The systems and techniques may also include the ability to sense the presence of at least a first orientation of the magnetic field with a magnetic field sensor including a conductor and at least two Wiegand-effect conductors as the magnetic field orientation is changed (512) and to generate an electrical pulse in the conductor with each Wiegand-effect conductor when the first orientation of the magnetic field is sensed (516).

Une mesure de processus peut être obtenue au moyen de systèmes et de techniques de génération de signaux de sortie en fonction des processus mesurés. Dans certains modes de réalisation, les systèmes et techniques de mesure de processus peuvent présenter la capacité à générer un champ magnétique (504) et à modifier successivement l'orientation du champ magnétique (508). Les systèmes et techniques peuvent également présenter la capacité à détecter la présence d'au moins une première orientation du champ magnétique à l'aide d'un capteur de champ magnétique comprenant un conducteur et au moins deux conducteurs à effet Wiegand lorsque l'orientation du champ magnétique est modifiée (512) et à générer une impulsion électrique dans ledit conducteur à l'aide de chaque conducteur à effet Wiegand lorsque la première orientation du champ magnétique est détectée (516).
