Precision Low Profile Load Cell
Model 41
DESCRIPTION
Model 41 is a low profile “pancake” type load cells. These
bonded foil, strain gage load cells are engineered to measure
loads from 5 lb to 500,000 lb. The tension/ compression
Model 41 is designed with the threaded hole running completely
through the center of the cell. Model 41 utilizes two stabilizing
diaphragms, which are welded to the sensing member to
reduce off-center and side-loading effects. It provides high
performance in non-linearity, hysteresis, and repeatability speci-
fications for such applications as tube mills, extruding processes
and weighing. Each unit has a welded construction and can be
hermetically sealed for added durability. Model 41 load cells are
available with optional 0 Vdc to 5 Vdc or 4 mA to 20 mA output.

NOTES
1. Allowable maximum loads - maximum load to be applied without
damage.2
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.
