Honeywell LFH-7I Subminiature Load Cell Datasheet
Model LFH-7I
Top Hat Subminiature Load Cell
DESCRIPTION
Model LFH-7I subminiature load cell is a low profile force
accuracy of ±0.7 % full scale. The top of the load cell is the area
transducer for applications with minimal space and high
where the force is applied and the base ring of the load cell
capacity requirements. This transducer utilizes foil strain gages
must be placed on a hard, machine-ground flat surface to obtain
to measure compression loads of up to 10,000 lb and achieves
optimum accuracy.

NOTES
1.

3.
4.
Accuracies stated are expected for best-fit straight line for all errors
including linearity, hysteresis and repeatability through zero.
Allowable maximum loads – maximum load to be applied without
damage.3
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.
This unit calibrated to Imperial (non-Metric) units.
