Single point load cells

TSM Control Systems of Dundalk in Ireland is using HBM's single point load cells to ensure high accuracy in its range of weigh blending systems. These measure a recipe of different plastic granules by weight and blend the resulting mix so that it can be used in different types of plastic processing.

TSM's machines vary in capacity from a maximum batch weight of 0.5kg in the smallest system to 32kg in the largest. Larger machines can take up to 12 different material components to make the final mixture.Most have a single HBM SP4M load cell but some of the larger models have two units.

Michael McKiernan, TSM design engineer, says: "We like the open construction of the SP4 load cells since there are no guards. This prevents granules from getting lodged around the load cells."
