Non-Repeatability 101

Interface 101 defines non-repeatability as the maximum difference between sensor output readings when the exact same load is applied repeatedly under identical loading and environmental conditions. Using load cells, understanding non-repeatability, why it governs a test's practical resolution limit, and how to isolate it from external test-rig anomalies is essential to designing dependable test protocols and accurate analysis.

How Measurement Solutions Dictate the Future of Energy Reserves and Grid Resilience

Interface measurement solutions for energy reserve management (ERM) support the technology, infrastructure, and mechanical systems that store, balance, dispatch, and secure secondary energy capacity in power grids, batteries, and energy systems. Interface load cells, torque transducers, ATEX sensors for hazardous locations, load pins, tension load links and shackles, and wireless telemetry products provide data to manage loads, monitor containment, and optimize storage dispatch.
Forces Of Product Testing

Beyond the Obvious Forces of Product Testing

True precision in testing requires developing a mindset that embraces failure, diagnoses invisible errors, and knows that the best results come from understanding that every component, connection, and procedure is part of a complex system that demands relentless attention. Interface provides high-accuracy test and measurement products, including load cells, for testing labs.
Moment Compensation 3

Moment Compensation Relevance for Aerospace, Robotics, and Structural Testing

Moment compensation is a fundamental engineering principle that ensures stability and accuracy by counteracting unwanted forces. Industries like aerospace, robotics, material and structural testing know precision is non-negotiable. At Interface, the moment compensation principle is a core part of our load cell design best practices, making our force measurement solutions a decisive component in some of the world's most demanding applications.
Consider Overload Protection

Key Considerations for Overload Protection in Load Cells

Overload significantly threatens the accuracy, longevity, and safety of force measurement systems. An overload occurs when the force exerted on a load cell surpasses its designated capacity limit. Discover how Interface load cells incorporate innovative features to reduce the risks associated with overloading. Interface offers a number of standard LowProfile and Mini load cells with overload protection.
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.

INTERFACE TECH TALK Moment Compensation

What is Moment Compensation?

Every Interface LowProfile™ load cell is moment compensated to minimize sensitivity to extraneous loads. Moment compensated load cells are designed to counteract the external forces or moments by using a configuration of strain gages and electronics that can detect and compensate for these forces. The strain gages are arranged in a way that allows the load cell to measure the force applied to it in multiple directions, and the electronics can then use this information to calculate the impact of external forces and moments on the measurement.
INTERFACE 101 SERIES OFF AXIS

Off-Axis Loading 101

Off-axis loading can affect the accuracy of load cell measurements, so it is important to take steps to protect against it. To minimize the effects of off-axis loading, load cells are often designed with measures to reduce sensitivity to forces applied in other directions. These may include mechanical features such as strain relief structures or specialized materials that are more resistant to off-axis loading. Additionally, load cells are often installed and used in ways that minimize the likelihood of off-axis loading, such as aligning the primary sensing axis with the direction of the applied force.
