load cell performance metric

Load cell performance metrics are the real language of a sensor's capabilities. Most spec sheets list accuracy, but that's an umbrella term. It combines non-linearity, hysteresis, and repeatability—each measured as a percentage of full scale. For geotechnical instruments, creep and temperature effect on zero balance often become the decision-makers. A load cell that drifts after a month buried in soil will cost more in recalibration than its purchase price. Kingmach's load cells are built with these long-term factors in mind. Our production checks include compensated temperature range validation and creep testing, so the metrics you see on the datasheet reflect performance under sustained load, not just a quick lab test. Moreover, sensitivity (mV/V) determines signal strength, which affects how far you can run cables without noise issues. A typical Kingmach load cell offers 2.0 mV/V or 3.0 mV/V, matching industry standards while allowing for customization if your data logger prefers a higher output. We also document non-repeatability as a separate value because in cyclic loading applications—like pile tests—it directly impacts confidence in each measurement. The specs are not just numbers; they're a promise of how the sensor will perform when it matters.
