Honeywell 31e High Miniature Load Cell Datasheet
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.

6.
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.
