LOAD CELLS SET FOR HARD TASK AT CONCRETE PLANT
When an OEM manufacturer required high accuracy load cells for a concrete batching plant, the company
turned to Thames Side Sensors. Steelfields of Gillingham supplied a batching plant to a concrete facility in
Abu Dhabi, where recent regulations on concrete mix require all materials to be weighed to an accuracy of within ±1%.
Thames Side Sensors were able to meet this with their T90 load cell.
Steelfields design and manufacture an extensive range of batching plant, and export to over 40
countries worldwide. The load cells are incorporated in all weigh operations at the new plant. They
weigh out the aggregate, the sand and stone, and cement and powders from their respective hoppers. These are
then fed into a 3m3 pan mixer. With the T90 load cells the plant is able to produce 120m3 per hour of quality
concrete, an unusually high output for such accuracy.
The T90 is a folded shear beam load cell designed for hopper, tank, and vessel weighing. It is
available in a comprehensive range of capacities, from 500kg to 7500kg, in one body size. It features a unique
folded shear beam design and is manufactured from high quality, corrosion resistant, tool steel, sealed to IP67.
It has an operating temperature of -40°C to 80°C, and a combined error of less than ±0.05% with respect to
rated output.
