The F308 is a compact axial loadcell with improved EFI compared to diaphragm loadcells.
The inert base and top fixings with spanner flats allow ease of installation. The strain geometry possesses a plane with good EFI performance defined as perpendicular to the loading axis and the spanner flats. This is particularly useful when a loadcell is used to support mass with its weight acting perpendicular to the measurement axis.
We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for higher temperature operation. Ranges from 500N to 2.5kN can be manufactured for fully compensated operation up to +250°C. Please consult our engineering department.

Notes
- AL = Applied load.
- RL = Rated load.
- AO = Average of tension and compression outputs for full 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.
When this loadcell is rationalised the resistors are housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are Ø10mm by 57mm.
