The ranges up to 50N are manufactured in aluminium; ranges above 50N are manufactured in stainless steel.

The F328 is an axial low force universal loadcell with quantified extraneous load and moment rejection.

Its high resistance 5000Ω strain gauge bridge makes this loadcell ideal for battery powered applications such as a laptop computer with a DSC USB loadcell digitiser or a hand held TR150 loadmeter.

The strain system exploits a laminated structure producing excellent extraneous force and moment rejection together with minimal translational deflection.

More information can be found in Engineering Application Sheet E034.

We are happy to design variants of this loadcell to meet your specific requirements. Please consult our engineering department.

Notes

  • AL = Applied load.
  • RL = Rated load.
  • Temperature coefficients apply over the compensated range.

Connections

The loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-1-4C.

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.

This loadcell has compensation components housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are Ø10mm by 57mm.
