How to Select an F/T System?

1. Calculate expected moment and forces

Moment capacity is usually the determining factor in choosing the best transducer model for your application. The end-effector attached to the transducer as well as the tasks being performed will generate forces on the transducer, which will result in a moment. The moment is the applied force (dynamic and static together) multiplied by the distance from the transducer origin to the point at which the force is applied. It is important to also consider overload conditions beyond the normal operating forces and moments the transducer will experience.

2. Identify transducer strength

Use the table on our F/T Models page to compare the measuring ranges of the transducer models available.

3. Verify resolution

Next, the required resolution should be considered. A fine resolution requirement can conflict with a transducer chosen based on moment capacity. Transducers with larger ranges have coarser resolutions

4. Inspect other transducer specifications

Compare the detailed specifications of the chosen transducer to those of your application requirements to be certain the chosen transducer is appropriate for your application.

Example:

The expected maximum measured load is 98 N (10 kg) of force and the end-effector is 25 cm long. The moment generated would be 24.5 Nm. The best F/T would be a Delta/SI-330-30 (330 N, 30 Nm) which can handle the 24.5 Nm moment. The maximum single-axis moment rating (Txy) of this model is 190 Nm, which should be sufficient for overload situations.
