Typical applications are in retail shop scales, industrial counting scales, pre-packing scales, batch weighing machines, money checkers, pharmaceuticals, medical and scientific instrumentation. Compression loads from the loading platform are applied directly enabling much simpler constructions without the requirement for levers, flexures or pivots; scale design and maintenance is therefore greatly simplified. The “UNIWEIGH” series load cell is particularly immune to eccentric loading, the load being commonly applied via a simple X or H frame whose loading points are at the corners of the load platform. The “UNIWEIGH” series load cells are available in two distinct sensitivities offering the customer considerably lower ranges of this device than were hitherto possible. The “UNIWEIGH” series cover full scale load ranges from as low as 100 grams to 50 kilograms.
