F254 Fatigue Rated Pancake Loadcell

Geometry: Shear web structure with high vertical and lateral mechanical stiffness.

The F254 is designed for high levels of cyclic loading and is readily adapted to series mechanical connection within actuator rods or pistons by using our ‘in-line’ adapter.

The loadcell has good output symmetry between compression and tension operation. All standard bi-directional loadcells are calibrated in both modes. If you require a recessed boss the F318 pancake loadcell may be more suitable. The F318 has standard ranges from 1 to 500kN.

We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department.

Details of our other loadcell families can be found in the Product Guide.

Notes

  1. AL = Applied load.
  2. RL = Rated load.
  3. AO = Average of tension and compression outputs for full load.
  4. Temperature coefficients apply over the compensated range.

Connections

The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 16-2-4C or a 4 pin Binder 723 series chassis plug.

Excitation + = Red or pin 1, Excitation - = Blue or pin 2, Signal + = Yellow or pin 3, Signal - = Green or pin 4, Screen = Orange.

Reverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.
