BM14K Analog Column Load Cell, 10-100 t Capacity (CAT#: STEM-BC-3372-ZJF)

The BM14K is an analog column-type load cell for heavy industrial weighing. It uses a stainless-steel single-column structure with compression loading. Rated capacities extend from 10 t to 100 t. Fully welded sealing provides IP68 environmental protection. The sensor is designed to withstand lightning surges up to the stated 10000 V level. Accuracy options include C3, C4, B10M, and A5M. Optional ATEX classifications support selected hazardous-area installations. It is suitable for truck scales, weighing modules, platform scales, and hopper scales.
