F319 Handbrake Loadcell

The F319 handbrake loadcell offers an excellent technical solution to measurement of an ergonomic force. The double shear web design and rigid low profile finger grip combine to maintain the same precision of measurement along the entire finger grip length. The typical unevenly distributed force applied by the human hand is measured with good repeatability and minimum error in a sense normal to the lever axis.

The F319 has been fitted directly to a handbrake lever and also adapted for production tests by using an easy fit socket moulding, as care must be taken to ensure that the hand clamping forces are not measured in addition to the handbrake pull force the moulding used a ‘dorsal fin’ to ensure hand clamping was avoided.

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

Application Tests

Uneven Hand Loading Errors

The uneven load distribution of a human hand has been replicated by applying point loads over the length of the loadcell. In the worst case, the extreme ends, the error is limited to <1% of the applied force.

Handbrake Angle Vector Errors

The F319 handbrake loadcell measures force perpendicular or normal to the handbrake lever. Variations of lever inclination angle can produce angular deviations between the applied force and the loadcell’s normal measurement axis. For angular deviations up to 33° to the loadcell's normal axis the load errors are limited to <1% of the applied force.


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


The F319 loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-1-4C. The cable is connected to the loadcell with a miniature 4 pin connector so that cable can be easily replaced if it is damaged.

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

The screen is not connected to the loadcell body.
