2580 Series Static Load Cells

Instron® load cells are a key part of a materials testing system. Instron is the only global materials testing supplier that designs and manufactures its own load cells. This ensures that Instron load cells meet the unique requirements of materials testing such as; high accuracy over a wide measurement range, high stiffness, resistance to offset loads, accurate alignment and excellent zero stability.

The 2580-xxxN Series load cells are specifically designed for use with 5900 testing systems; offering exceptional performance with the ability to measure forces as low as 1/1000th of the force capacity to an accuracy of 0.5% of reading. The load cells can withstand loads up to 150% of their force capacity without damage and 300% without mechanical failure. Automatic transducer recognition and electrical calibration, makes them easy to use.  The load cells allow the user to zero out the tare weight of a grip or fixture that weighs up to 10% of the force capacity, while still maintaining the full specified accuracy.

All Instron load cells are individually temperature-compensated and tested for accuracy and repeatability on calibration apparatus that is traceable to international standards, with a measurement uncertainty that does not exceed one-third of the permissible error of the load cell.


  • Force capacities from ±500 N to ±600 kN (50 - 60,000 kgf or 112 -137,000 lbf)
  • Suitable for a range of test types, including tension, compression,cyclic and reverse stress
  • Accurate measurements down to 1/1000th of load cell capacity means fewer load cells and fewer load cell changes
  • Automatic recognition with electronic serial number and electrical calibration allows for simple, error-free operation
  • 150% of force capacity overload capability –reduces the possibility of damage
  • Tare weight 10% of force capacity – can be used with a wide range of grips and fixtures
  • Can be used with optional Quick Change and Piggy Back Adapters to facilitate a quick changeover of load cells
  • Precision machining and construction along with high axial and lateral stiffness helps to maintain system alignment
  • Low sensitivity to offset loads improves consistency of results
  • Complies with all international force measurement standards, including ASTM E4, ISO 7500-1 class 0.5, and JIS B7721, B7733
