Relation entrée-sortie d'un transmetteur. (mise en équation)
 
Dans la grande majorité des applications le signal de sortie est proportionnel 
à la grandeur mesurée: la loi est linéaire.


S= 0S /EE  (E-Dz)+Ts 
E= (S-Ts)*EE/0S   + Dz

S=sortie
E=entree
Dz = decalage zero    (+petite valeur axe X)
EE= etendue d echelle ou Span (axe X)
Ts= talon de sortie      (+petite valeur axe Y)
0s= echelle de sortie    (axe Y)

Pour certaines applications (mesure de débit par OD) le transmetteur est 
équipé d'un étage extracteur de racine carrée.

S= 0S / sqrtEE      sqrt(E-Dz)+Ts 
E=  EE*(S-Ts)**2 / 0S**2      + Dz


Pourcentage : Valeur-Ts / Max-Ts (0s)
