F325 High Accuracy Web Tension Loadcell

This high precision web tension loadcell is designed and built to meet the needs of machine designers, installation fitters and end users by the incorporation of alignment features with maximum flexibility. The high performance of this loadcell is not compromised by the relatively large errors that can be produced by imprecise installation.

We are happy to design variants of this loadcell to meet your specific requirements.

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

  1. AL = Applied load.
  2. RL = Rated load.
  3. Temperature coefficients apply over the compensated range.


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

Excitation + = Red, Excitation - = Blue, Signal + = Yellow, Signal - = Green, Screen = Orange.

The screen is not connected to the loadcell body.
