The F305 is a high performance loadcell for measuring seat belt tension forces.
Its geometry was created by computer program to generate an optimal design with minimal mass, material usage, stress and deflection. The outer bars can easily be removed allowing fitting to a seat belt while it is anchored at both ends.
The performance figures are typical values and are dependant on belt type. We can carry out a 5 point calibration using a 2 metre sample of customer supplied belt to reduce application errors. The calibration data can be used to reduce non-linearity errors in test results.
We are happy to design variants of this loadcell to meet your specific requirements. Please consult our engineering department.
