Model 31E High High Range Precision Miniature Load Cell DESCRIPTION Model 31E high range precision miniature load cells measure term stability for ranges 1000 grams and above.) A modification both tension and compression load forces of 10 kN to 50 kN. permits this model to be completely welded for underwater These models are our highest accuracy, rugged miniature applications. The Model 31E tension/compression load cell has load cells. Model 31E’s welded, stainless steel construction is male threads attachments. High accuracies of 0.15 % to 0.25 % designed to eliminate or reduce to a minimum, the effects of full scale are achieved. Each bonded strain gage unit is built of off-axis loads. (The internal construction assures excellent long- welded 17-4 PH stainless steel for additional ruggedness.

Allowable maximum loads – maximum load to be applied without damage.2 Without damage - loading to this level will not cause excessive zero shift or performance degradation. The user must consider fatigue life for long term use and structural integrity. All structurally critical applications (overhead loading, etc.) should always be designed with safety redundant load paths. Standard calibration for tension/compression load cells is in tension only. TEDS available with integral cable units only. This unit is calibrated to Metric (non-Imperial) units. Signature calibration only available as inline module. TYPICAL SYSTEM DIAGRAM Warranty.
