Manufacturing loadcells since 1972
F209 Donut Loadcell
Standard Ranges 1000, 2000 and 4000kN (100 to 400tonnef)
Geometry: Axial strain cylinder in a sealed case, with raised end load bearing faces and hole right through. For use in compression or in fail-safe tensile applications.
The F209 is ideally suited to engineering force measurements including through centre safety testing of cables, rods and bolts.
It is designed for easy installation, usually between two flat faces bearing on its loading rings, either unattached or with retaining spigots positioned in the centre hole. Alternatively tensile load transfer can be achieved via a tie rod assembly through the centre hole. In this way the loadcell can indirectly measure tensile loads in a "fail-safe" mode.
We are happy to design variants of this loadcell to meet your specific requirements. 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 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.
The screen is not connected to the loadcell body.
