Equalizing Load Cells in Multi-Cell Systems
Interface details steps for multi-cell systems, such as those used in large-scale weighing and force measurement applications, to ensure each load cell carries an equal portion of the load is critical for accuracy and reliability. Uneven loads can lead to inaccurate data, damage, and potential failure of the load cells.

Comparing Shear Versus Compaction Force Measurement
Interface load cells are used in shear and compaction force measurement. Understanding the differences between shear and compaction is determinative, as it directly impacts applications, sensor choices, and output data for testing analysis. Learn about shear force versuse compaction, also known as compressive, measurement, applications and load cell types. This understanding aids in making informed test and measurement decisions in material science, mechanical engineering, and industrial automation.

Side Load Sensitivity 101
Interface 101 highlights the side force effect, side load sensitivity, and eccentric load sensitivity. Side load sensitivity is how a load cell's output is influenced by a side force. It reveals the load cell's sensitivity to forces applied off its intended axis. A side force effect in compression testing with load cells refers to a force applied perpendicular to the intended axial compression force. This can happen due to misalignment between the load cell under test and the testing machine's loading plates.

Detailing Sensor Rated Output Millivolts Per Volt
Interface sensor specifications state rated output, expressed in millivolts per volt (mV/V), as the electrical output of a load cell, multi-axis sensor, or reaction torque transducer in mV/V of excitation at the rated load. It essentially expresses a load cell's sensitivity. RO represents the change in output voltage in millivolts of the load cell relative to a change in the excitation voltage in volts applied to it.

How Do You Know if Your Load Cell Needs Calibration Service or Repair?
Interface Calibration and Repair Services answers when a load cell might need repair. One sign is if the zero balance has shifted significantly since it was first installed. This could indicate that the load cell has been overloaded or damaged. Another sign is if the output varies significantly when the same load is applied. This could also indicate a mechanical issue.If you suspect that your load cell is damaged, you can perform a quick diagnostic check using an ohmmeter. This will help you determine if the bridge circuitry and zero balance are within specifications. If not, then the load cell should be sent to Interface for further evaluation and repair.

Creep 101
Interface defines creep, an important accuracy specification for load cells, in the essential 101 Series. When a force is applied to a solid material within its elastic limit, the resulting deflection will subtly increase over time if the force is held constant. This phenomenon, known as creep, is not permanent but recoverable. It's important to note that the signal from a load cell exhibits this creep, making it a key consideration in all load cell applications.

Understanding the Anatomy of Fatigue Failure
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.
