Description
Fatigue Rated Low Profile Universal Shear Web Load Cell Model F140, F141, F142
The F140, F141, and F142 are suitable for use in material testing machines, airframe test fixtures, vessel
and silo weighing, level control of tanks holding liquid and bulk materials, and any application requiring
a load cell that has a low profile, a small diameter, a high degree of stiffness, fatigue rating, and
resistance to the negative effects of extraneous forces. For universal or tension only applications, the
F140, F141, and F142 are usually bolted to a surface or plate that is flat and parallel within ±0.0002 inch.
For compression only applications, a load button with a spherical loading surface and with threads that
will engage the threads found in the center-loading hole of the F140, F141, and F142 should be used.
SensorData will supply a tension plate and spherical load button as options.
