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 
  • HBM accuracy class: 0.02 to 0.05
  • Capacities: 2.5 kN to 2.5 MN

Now available: U15 with improved technical data

  • Improved technical data for many key values (creep, TK0, hysteresis)
  • Extended measurement range: Meets the requirement of class 0.5 according to ISO376 from 10%
  • Now also available as a tension/compression reference transducer with maximum capacity of  up to 2.5 MN

High accuracy class

  • Complies with the requirements of accuracy class 0.5 per ISO 376
  • 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
  • HBM enables the U15 together with the amplifier to be calibrated as a measurement chain (competence of the HBM calibration laboratory)
  • Option: Delivery as a calibrated product (calibration through HBM’s ISO 17025-accredited calibration laboratory) 

Optimal complete solution including calibrated accessories for reliable transfer measurement

Small displacement

  • Small displacement
  • As a result: High stiffness and excellent dynamic behavior
  • High resonance frequency for dynamic calibration tasks
  • Robust due to IP67 degree of protection and hermetic sealing resulting in outstanding long-term stability
  • Small TKZero and low sensitivity to temperature gradients

Measurement accuracy, even in dynamic or harsh conditions. Minimal displacements. 

Extensive range of accessories

  • TEDS
  • Tensile force application per ISO 376
  • Thrust pieces per ISO 376
  • Knuckle eyes
  • Various connection cables in different, practical lengths and with plugs, soldered on for connection to the amplifier, on request.

A complete measuring chain: Perfect precision for a perfect price.

Using the double-bridge configuration, the U15/MX238B measuring chain can be easily used e.g. in testing machines.

The combination of the reference transducer U15 and the precision measuring amplifier module QuantumX MX238B results into an extremely cost-effective precision measuring chain. Thanks to the modular design of the QuantumX modules, you can also easily extend this measuring chain by a number of additional measuring variables, e.g. Temperature, voltage, angle of rotation.
