Why is Metrology Fundamental to Test and Measurement?

December 2, 2025

Metrology, the science of measurement, is the foundational pillar of the test and measurement industry. Metrology is critical for quality control, regulatory compliance, and the development of new products and processes across a wide range of industries. Interface LowProfile Load Cells and Gold Standard Calibration Solutions are standards of measurement excellence required in metrology.

INTERFACE TECH TALK Resistance Output Vs Rated Output

Resistance Output Versus Rated Output

July 22, 2025

Rated Output (RO) is the dynamic electrical signal that directly represents the applied mechanical force. Resistance Output is a static electrical characteristic of the load cell's internal circuitry. When you are performing force measurements, you are primarily interested in the Rated Output. This value, in conjunction with your excitation voltage, enables you to accurately convert the measured millivolt signal into engineering units of force in lbf or Newtons. Discover how load cells work at the ultimate force measurement resource hub, Interface ForceEDU.

How Do You Define A Load Cell Error Budget?

October 24, 2024

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 the Anatomy of Fatigue Failure

March 21, 2024

Interface fatigue-rated load cells are designed to meet the demands of fatigue testing. As load cells are structural devices stressed during their normal use, they are commonly given ultimate overload ratings to characterize the magnitude of static load they will withstand without failing structurally. Learn more about fatigue theory from Interface force measurement experts.

Are Load Cells Used in Vacuum Environments?

July 24, 2023

Interface provides load cells thare can be used in a vacuum environment. However, not all load cells are created equal or suited for this specialized use case. Vacuum testing labs are used by a variety of industries, including aerospace, medical, and defense. These labs are common for material process testing and used in R&D. Vacuum testing helps to identify potential problems with products and materials before they are used in a vacuum environment. Using quality load cells that are manufactured by force measurement experts in sensor technologies and experienced in working with vacuum testing labs and experts is an important consideration.
