U15 Precision Load Cell
Combining Technology with Experience
The amazingly cost-effective U15 force transducer is ideally suited for use both as a transfer standard and as a reference sensor in calibration machines. The U15 reference transducer is the perfect choice for demanding test benches requiring minimal displacements combined with high accuracy and a high output signal.
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.
