Un premier transducteur de tension (126) est disposé en vue de supporter la longueur de bande et un deuxième transducteur de référence (127) est positionné en une relation diamétralement espacée par rapport au premier transducteur. Un signal de référence en provenance du deuxième transducteur est soustrait du signal en provenance du premier. Le résultat de cette soustraction fournit un signal représentatif de la tension de la bande.
