INTERFACE TECH TALK Error Budget

How Do You Define A Load Cell Error Budget?

Interface tech talk answers why a load cell error budget matters. An error budget quantifies every factor that can cause the load cell's output to deviate from the true weight or force being measured. A defined error budget is the maximum time a technical system can fail without service-level consequences. In force tests and measurements, it is sometimes called an uncertainty budget. An error is the difference between the measured value and the true value.

Understanding GUM and Measurement Uncertainty

GUM, the Guide to the Expression of Uncertainty in Measurement, defines terms and concepts related to uncertainty. GUM describes methods for uncertainty calculation, and offers guidance for reporting and the documentation of uncertainties in measurement results. Interface knows that understanding GUM and the adherence to good test and measurement practices are essential to minimize uncertainties and ensure reliable measurement results for every application. In addition, reducing uncertainty with regular calibration of testing devices and proper maintenance of the equipment go hand-in-hand with GUM.
