Manufacturing loadcells since 1972
F257 Axial Compensated Loadcell
Standard Ranges 80, 120, 160 and 240kN (8 to 24tonnef)
Geometry: Beam and diaphragm combination. Tension, compression and bi-directional options are available. All standard bi-directional loadcells are calibrated in both modes.
The loadcell's unique strain system compensates for typical force misalignment in force measurement rigs and industrial weighing systems. Its various end fixing options are all inert and easily modified for direct inclusion in mechanical assemblies.
The basic versions of the F257 are all sealed to IP65. If better sealing is required IP67 is available as an option. Integral 4 to 20mA or ±10V output amplifiers can be fitted as an option. Additional information can be found in Engineering Application Sheet E032 and the ICA6H data-sheet.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for operation up to +250°C. Please consult our engineering department.
Details of our other loadcell families can be found in the Product Guide.

The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 16-2-4C.
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.
