<p>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.</p> |
