Robot traction
Legged or wheeled robots pull a fixed anchor; measure peak and sustained traction.
FA-F Series
Force Testing System
A high-resolution load-cell system for traction, friction and break-strength testing. 125 Hz sampling catches every transient peak, and each test ends with a report you can hand to a customer.
- 50 kg – 2 t
- 125 Hz
- 24-bit
- ±0.05 % FS
- IP67
System architecture
Sensor, acquisition and software — integrated
The load cell’s mV/V signal is digitised by a 24-bit bridge DAQ and streamed over USB to the test software, which handles zeroing, calibration, quality control, logging and reporting.
Key features
Designed for data you can defend
One-click zero & noise check
Zeroing also measures idle noise and sets a noise band, so no false loads at rest.
True raw peak
Filtering is for display only; peaks always come from unfiltered data — no clipped maxima.
Automatic plateau analysis
Finds the longest, steadiest loading plateau and reports mean, σ and CV.
Professional reports
Annotated chart, plain-language findings, report ID and sign-off — ready to hand over.
Multi-point calibration
≥ 5-point calibration with standard weights; parameters stored with every record.
Open raw data
Every sample saved to CSV / JSON with timestamps and quality flags; Excel-ready.
