Manufacturing loadcells since 1972
Engineering Application Sheet E033 - F312 Custom Shear Pin Loadcell
The F312 only measures a bi-directional single axis force. It does not measure variable vectors. A shear pin will not provide the same structural integrity as a solid inert axle or pin that it is intended to replace.
Shear pins must not be considered as precision loadcells due to the following:
Uniformly Distributed Load Type
High strength and structural integrity
Low Bending Stress
Best Suited For Lifting Equipment Or Safety Critical Applications
The bearing fit tolerances in end support and pulley bearings provides higher structural stability and strength.
The bearing surfaces are often imperfect and produce reactions that vary in position with the applied load.
Point Load Type
Lower strength and structural integrity
High Bending Stress
Best Suited For Static Pins Or Process/R and D Force Measurements
The precisely positioned reaction points are designed to provide high repeatability and low hysteresis resulting in higher performance.
The higher bending stress and point load effects reduce the structural integrity.
Possible Design Features
We can manufacture shear pin loadcells to your specific requirements. If you fill in the F312 data-sheet and send it we will respond with a quotation, usually within 24 hours. Alternatively you can print the F312 data-sheet and fill in the blanks on the table and fax or post it to our sales department.
