Manufacturing loadcells since 1972
F300 Sideload Rejection Loadcell
Standard Ranges 1, 2, 5, 10, 20, 50, 100, 200 and 400kN
Benefiting from advanced machining techniques, the F300’s complex beam structure offers reliable error compensation in a cylindrical, 'donut' style footprint.
Whereas the long established 'donut' products such as the F202 require near perfect loading conditions, the F300's unique strain system compensates for typical axial misalignment as well as the combination of large sideloads and small moments. This has been used to good effect in ‘Junkers’ test machines, subjected to an extreme, rapid cycling of large sideloads, for bolt tension and 'self-loosening' fastener tests. Further details of this application, along with simple error equations for the F300 loadcell can be found in Engineering Sheet E036.
The circular patterns of fixing holes are deliberately over engineered to withstand potentially large moment effects and allow tension, compression and bi-directional versions as standard. There is also the added potential for customer supplied adaptor plates to give versatile end fixing options. Note that care should be taken to ensure the correct lengths of screws are used and that these are torqued correctly as given in E036.
We are happy to design variants of this loadcell to meet your specific requirements. Ranges above 5kN can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department for further information.
Details of our other loadcell families can be found in the Product Guide.

For ranges up to 50kN the loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-2-4C. Ranges above 50kN are fitted with 16-2-4C cable.
Excitation + = Red, Excitation - = Blue, Signal + = Yellow, Signal - = Green, Screen = Orange.
Reverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.
For rationalised ranges up to 5kN the resistors are housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are Ø10mm by 57mm.
