U93A

U93A is a miniature force transducer for tensile/compressive forces well suited for many applications in production. The sensor is suitable for very fast force siganls so that you can use it for experimental tasks even for high dynamic tests. Easy to mount due to flanges on both sides, IP68 rated. Available with IO -Link interface or as amplified version with 4-20 mA or 0-10 V.

Miniature force sensor U93A: Miniature force transducers for tensile and compressive forces for flange mounting

The small, robust and very stiff U93A reliably measures static and highly dynamic tensile and compressive forces. Its small dimensions and good dynamic properties make it a cost-effective alternative to piezoelectric force sensors. The mechanical connection is straightforward and secure due to the U93A’s flange screw connections on both sides. The sensor has an IP68 protection rating, making it suitable for outdoor use as well.

Like all force transducers from HBK, the U93A is easy to configure, allowing it to easily adapt to various conditions. Its design, featuring supporting diaphragms, makes the sensor exceptionally robust and resistant to lateral forces. Additionally, an important detail for production environments is that the cable of the U93A force sensor is compatible with drag chains and is oil-resistant.

New: Now with greatly improved accuracy and, on request, can be equipped with a permanently connected amplifier module.

HBM accuracy class: 0,2

Nominal forces: 1 kN ... 50 kN

Outputs: IO-Link, 0 – 10 V, 4 – 20 mA, mV/V (passive)

Ready for immediate use

Sensor available as a fully calibrated, ready-to-measure measurement chain
User-friendly configuration with the HBK configuration system
Various interfaces: V, mA or IO-Link output
Optional plug mounting for HBK measurement amplifier
TEDS on request

Individual configuration, quick flange mounting and simple commissioning. Ready for Plug and Measure.

Robustness redefined

Protection class IP68
Welded construction
Welded constructions made of stainless steel according to DIN standards
Cable is compatible with drag chains and resistant to almost all operating fluids
Extremely high shear force resistance
EMC-tested
With IO-Link: sensor health monitoring

Despite its compact design, the sensor consistently provides reliable results. Stable even in challenging conditions. Digital sensor health monitoring alerts to potential overloads.

Small and fast

Compact design, ideal when space is limited
Small diameter
Very low deformation under load, high rigidity, very high natural frequency

Ideally suited for force-displacement measurements in combination with displacement transducers and measurements of fast processes.
