U15 Precision Load Cell: Calibrating Forces from 2.5 kN to 2.5 MN

The U15 precision load cell (reference force transducer) reliably measures tensile and compressive force up to 2.5 MN. It is ideally suited for use as the master sensor in calibration machines, for challenging tasks in test benches, and as a transfer standard (e.g. when verifying or calibrating material testing machines or taking transfer measurements to ensure traceability of calibration machines to a standard).

As the transducer is showing vey low displacement, the geometry of the test stand is also stable under load. The U15 precision load cell's high resolution, excellent signal-to-noise ratio and low measurement uncertainty are based on the transducer’s high output signal (>4 mV/V from 25 kN). This allows for optimal utilization of the subsequent electronics’ measuring range.

U15 meets the requirements of class 0.5 in accordance with ISO 376. Its radially symmetrical design makes the sensor insensitive to temperature gradients. The U15 precision load cell is very robust due to its high IP67 degree of protection and the use of stainless steel materials.

Accuracy class (per ISO 376:2011): 0.5 in the range of 10% and 100% of the nominal load
HBK accuracy class: 0.02 to 0.05
Capacities: 2.5 kN to 2.5 MN

High accuracy class

Complies with the requirements of accuracy class 0.5 per ISO 376 in the range between 10% and 100% of its capacity
High output signal, > 4 mV/V for many capacities
Signal adjustment to 3 mV/V available as an option
Excellent signal-to-noise ratio
Good repeatability in varying mounting positions through electronic bending moment compensation
Transfer standard for tensile and compressive force up to 1 MN

Standard-compliant precision, also under unfavorable conditions of use. Absolute reliability.

Individual configuration

Double bridge version available on request: One output can be used as a reference signal, one output as an input for the machine control (also for machines with high forces and loads).
Application-oriented accessories such as TEDS, ISO 376-compliant load application and knuckle eyes
HBK enables the U15 together with the amplifier to be calibrated as a measurement chain (competence of the HBK calibration laboratory)
Option: Delivery as a calibrated product (calibration through HBK’s ISO 17025-accredited calibration laboratory)

Optimal complete solution including calibrated accessories for reliable transfer measurement
