Load Pins


Sentran’s force sensing Load Pins utilize a proprietary internal strain gaging process perfected over more than two decades. In most instances, a dual shear arrangement yields optimal results. For less demanding applications, or in the case of a cantilevered pin situation, a single shear section is an excellent alternative. The force sensing Clevis Load Pin provides an accurate method for achieving precision force measurements by replacing existing clevis bolts, shear pins, shear axles or other pinned joint devices employed by aerospace, automotive, energy, marine, structural testing and many other industries.


The same technology utilized in Sentran’s dual shear Clevis Load Pins is applied to its Shackle Load Pin products. Shear sensing strain gages are precisely positioned along with all the complementary compensating electronic components in an axial bore through the load pin center-line, referred to as the “neutral plane”. Precise positioning ensures that only those stresses induced by shear forces are precisely measured, proportionate with the load applied. This methodology allows for accurate transmission of shackle loading forces into the load pin sensing sections, while ignoring unwanted influences from bending and torsion effects.
