Crosstalk

Controlling Crosstalk in Multi-Axis Force Measurement Systems

Interface details the mechanical considerations and best practices for managing crosstalk. Using multi-axis sensors, crosstalk occurs when a load applied strictly to one axis produces a parasitic signal in another. For Interface instrumentation and sensor systems, managing this requires minimizing mechanical coupling at the flexure and applying mathematical compensation through precision electronics.
Bridge Completion 1

Bridge Completion Considerations

Interface's use of the Wheatstone bridge is considered world-class in load cell design and for its ability to produce accurate measurements. Selecting the right instrumentation and ensuring proper bridge completion are technical necessities for maintaining the integrity of your force measurement data. Our bridge completion solutions simplify selecting the right instrumentation device to pair with your sensor, making it easier than ever to achieve high-quality measurements.
INTERFACE TECH TALK Overload Detection

How Does Load Cell Overload Detection Work?

Load cell overload occurs when the force applied to a load cell exceeds its rated capacity. Load cells are designed to operate within specific load limits. Overload detection is essential to protect these costly and sensitive devices from damage and ensure the longevity and reliability of the sensors. Without proper overload protection, these sensors can be compromised, leading to inaccurate readings or permanent damage.
Shear Versus Compaction

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.
INTERFACE 101 LOAD CELL SIMULATOR

Load Cell Simulator 101

A load cell simulator is a device that mimics the electrical signal of a load cell. This allows technicians to test and calibrate measurement systems without applying physical force or weight to the load.   Interface load cell simulators are an essential accessory and valuable investment for any testing lab or research facility frequently using load cells. These simulators can help to improve safety, reduce downtime, improve accuracy, lower costs, and increase convenience. 
INTERFACE 101 EXCITATION

Excitation Voltage 101

An excitation voltage is needed to power the load cell and ensure the output signal is accurate. Load cell excitation is necessary to ensure the accuracy and reliability of load cell measurements. Interface provides electrical performance data on all specifications represented as VDC MAX, when applicable.  The data for excitation voltage is listed under the electrical section of a transducer model’s specification datasheet, along with other factors, including rated output, bridge resistance, and zero balance.

INTERFACE 101 SERIES CALIBRATION CURVE

Calibration Curve 101

Interface Calibration Curve 101 defines why the calibration curve is essential for ensuring the accuracy of force measurements. The calibration curve allows for the determination of the load cell's sensitivity, linearity, and any potential adjustments or corrections needed to improve its accuracy. For traceability, serves as a reference to convert the load cell's output signal into meaningful and calibrated measurements when the load cell is used for force or weight measurement applications. Interface recommends all load cells be calibrated annually, at a minimum.
Load Cells Versus Piezoelectric

Load Cells Versus Piezoelectric Sensors

Load cells and piezoelectric sensors are used in all types of measurement applications. Interface load cells measure the amount of force or weight being applied to them. The amount of force is numerated by the capacity of the model design, such as 50lbf (pounds-force) or 5kN (kilonewton). Piezoelectric sensors work on the principle of piezoelectricity. They are made of materials that generate an electric charge in response to mechanical stress, such as pressure or vibration.
