Overview
The Kunwei HPS92 is a six-axis force/torque sensor for measuring forces and moments in robotic systems. Its 92 mm diameter, 28.6 mm height and titanium-alloy body provide a low-profile format for integration. HPS92A, HPS92B and HPS92C offer different measurement ranges, with Fz ratings of 500, 1,000 and 2,000 N respectively. RS422 / Ethernet communication and sampling up to 30,000 Hz support force-data acquisition.
Features
- Measures three force components, Fx, Fy and Fz, and three moment components, Mx, My and Mz.
- Three versions provide different force and moment ranges; accuracy is 0.3% FS for HPS92A and HPS92B, and 0.5% FS for HPS92C.
- Circular, low-profile body with a central opening, mounting holes and a recessed circular side connector.
- High-performance titanium-alloy construction, with a listed weight of 0.45 kg for each version.
- Resolution of 0.03% FS, repeatability of 0.1% FS and overload level of 500% FS.

Applications
- Robotic-arm contact-force measurement: Measure forces and moments during controlled contact tasks, using all six measurement components to assess loading direction as well as magnitude.
- Robot load testing: Record force and moment data during development tests. The three versions provide different measurement ranges within the same listed 92 mm diameter and 28.6 mm height.
