F318 Pancake Loadcell

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

The loadcell has good output symmetry between compression and tension operation. All standard bi-directional loadcells are calibrated in both modes.

Ranges up to 20kN have counter bored and tapped outer fixing holes enabling versatile fixing options without loss of the low height advantage.

The F318 pancake loadcell has a recessed boss. If you require a raised boss the F254 may be more suitable. The F254 has standard ranges from 25 to 200kN.

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 Loadcell Specifier 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 7-2-4C for ranges up to 20kN. Ranges above 20kN are fitted with 16-2-4C cable. A 4 pin Binder chassis plug option is available instead of the cable. For the ranges up to 20kN the plugs are 712 series, for 50kN and above 723 series are used.

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.
