U3 Force Transducer: Capacities ranging from 0.5 kN to 100 kN

The U3 load cell is based on the diaphragm principle; which means the strain gauges are mounted within the load cell housing in a well protected manner. Due to the design of the supporting membrane, the U3 force sensor guarantees an exceptionally high lateral force stability of up to 100%.

The U3 has a bending moment adjustment, so that acting moments as well as transverse forces are largely compensated for. The robust design is combined with a double-sided flange connection. This allows the sensor to be mounted quickly (within a few minutes): this minimizes downtime in production. The accuracy exceeds the typical requirements in manufacturing applications.

HBK accuracy class: 0.2
Nominal forces: 0.5 kN to 100 kN

Practical

Hassle-free mounting via flange with integrated centering points
Can be easily connected to an electrical source
Optional: Adapter for connecting knuckle eyes, as well as plug-in connectors and TEDS

Minimal assembly time and high operational safety during production, monitoring and test tasks.

Robust

Exceptional lateral force stability thanks to special support membrane construction
High torsional and bending moment stability
Stainless steel design
Standard at HBK: High immunity to electromagnetic fields

Proven reliability: Measurement results are immune to the effects of transverse forces, bending moments, torsion and electromagnetic fields.
