The F318 features a shear-web construction engineered to provide exceptional stiffness both axially and laterally, making it suitable for demanding measurement environments. This structural arrangement supports the performance expected from universal pancake load cells, especially in applications requiring compact form factors without compromising mechanical integrity.
A key advantage of the F318 is its balanced response when used in either compression or tension. Each bi-directional unit undergoes calibration in both loading directions, ensuring dependable and repeatable output across its full operating envelope. For capacities up to 20kN, the design incorporates counter-bored and threaded outer mounting points, allowing flexible installation while preserving the low-profile geometry.
This model includes a recessed loading boss as standard. For applications that require a raised boss instead, the F254 series may be a more appropriate option; that range is available in capacities from 25kN to 200kN and aligns with many of the functional expectations associated with universal pancake load cells.
Custom engineering support is available for projects requiring modified geometry, tailored mounting provisions, or extended operating conditions. Special versions can be produced with full compensation for temperatures reaching +250°C, and our engineering team can advise on how best to configure the sensor for your application. Additional information on other load cell types and families is available in the Load cell Specifier Guide.
Overall, the F318 provides a rugged, low-height measurement solution suitable for users who need reliable performance in both compression and tension within a compact shear-web design.
