Overload Protector Load Cells
The Lebow Load Cell Overload
Protector is available in sizes that will accommodate load
cells with capacities up to 3,000 lbs. and overloads to
15,000 lbs. in tension and 20,000 lbs. compression.
The Lebow Load Cell Overload Protector is available with an
optional end plate assembly and rod ends. The Overload
Protector eliminates downtime and replacement costs due to
damaged strain gage load cells. The unit does not
appreciably affect the cell’s dynamic response. Up to its
set point (usually 110%), the application of load results in
linear deflection of the system. At 110% of rated load, the
patented non-linear spring supporting the cell abruptly
collapses, shunting the load in excess of 110% to the
built-in mechanical stops.
When the load is removed, the springs automatically return
to their original position. The low spring rate, above rated
load, allows wide tolerances in mechanical stop settings.
