A vehicle on-board weight indicator (10) comprising a converter means (11), an electrical signal receiving and processing means (12) and a numeric display (13). The electrical signal receiving and processing areas is typically a PLC although a specifically designed circuit can be employed. The converter means includes a first conversion stage comprising a linkage (14) connected at one end (15) to a fixed position relative to an axle (16) and at its other end (17) to a level actuator (18), the level actuator being secured to the vehicle chassis (not shown). The chassis is suspended above the axle (16) via a spring suspension (19) and as the vehicle is loaded, the distance between the axle (16) and the chassis changes according to the applied load.

Un indicateur (10) de poids embarqué pour véhicule comprend un convertisseur (11), un circuit (12) de réception et de traitement du signal électrique et un afficheur (13) numérique. Les zones de réception et de traitement du signal électrique sont en général un PLC, mais on peut utiliser un circuit de conception spécifique. Le convertisseur comprend un premier étage de conversion qui est doté d'une liaison (14) reliée à une extrémité (15) à une position fixe par rapport à un essieu (16), et à l'autre extrémité (17), à un dispositif (18) de commande de niveau fixé au châssis du véhicule (non représenté). Ce châssis est suspendu au-dessus de l'essieu (16) par une suspension (19) à ressorts et, quand on charge le véhicule, la distance séparant l'essieu (16) et le châssis varie selon la charge.
