Abstract
A scale is designed to be lightweight and easily portable. The scale comprises two weighing assemblies connected by a flexible joint so that the two assemblies may be folded against each other to form a compact case. Each weighing assembly comprises a weighing platform connected by resilient support members to a based. Weight measurement is effected by a Hall effect sensor in each weighing assembly which measures the variation in magnetic flux density caused by the movement of magnets mounted on the platforms when a load is placed on the platforms. Output from the Hall effect sensors is summed and the total weight is displayed on a digital display.
