These 0.25% accuracy load cells are constructed of all welded stainless steel, are hermetically sealed, and have a robust cable strain relief. These application specific load cells have transient voltage protection for lightning and/or power line surges. Each load cell is shock and vibration rated during the manufacturing process.

Electrical output is 2 mV/V and as mV/V units, these passive devices are inherently intrinsically safe. Standard full scale capacities range from 20,000 lbf. to 80,000 lbf. Customer specific configurations can also be designed.
