This document describes the features and characteristics of the U3 force transducer, including nominal force, accuracy, etc. The force transducer features tensile/compressive force transducers, low overall height, high dynamic load-carrying capacity, and stainless steel housing.
The HBM U3 series provides robust tensile/compressive force measurement with a low overall height, flanged ends on both sides, and stainless‑steel housing. Integrated lateral force compensation and a high dynamic load‑carrying capacity make it suitable for demanding industrial applications.
The datasheet lists detailed specifications such as accuracy class 0.2, input resistance > 345 Ω, isolation > 2 GΩ, and an excitation voltage range of 0.5 V to 12 V. Accessories include adapters and knuckle‑eye mounts, and installation can be performed with or without an adapter.
