EMSC Systèmes de mesure linéaire Mesure magnetique de la longueur avec sorties sinus/cosinus de 1 Vpp
- Signaux de sortie sinus/cosinus proportionnels à la vitesse
- La mesure de 2 mm de mouvement donne une période sinus/cosinus
- Distance de montage par rapport à la bande magnétique jusqu'à 0,8 mm
EMSC1 : électronique d'évaluation externe
EMSC2 : électronique d'évaluation intégrée, petite conception
