How Do Universal Testing Machines Use Load Cells?

Universal testing machines (UTMs) are essential for material qualification, structural research, and quality assurance. Interface load cells sit directly in series with the moving crosshead and the upper specimen grip of a UTM. A machine controller reads the load cell continuously within a closed feedback loop to regulate crosshead travel, maintain constant loading rates, or hold targeted force thresholds during stress relaxation evaluations. The transducer measures the specimen resistance as it deforms. The data acquisition system pairs this instantaneous force data with displacement data to measure elasticity, yield point, and ultimate tensile strength.

INTERFACE TECH TALK Thermal Specifications 1

How Do Thermal Specifications Influence Sensor Selection?

Interface Tech Talk details the differences between compensated and operating temperature ranges in load cell specifications. Thermal variables influence sensor accuracy, the mechanics of static deflection. Thermal gradient, material, strain gages, and repeatability are important when selecting a sensor. Only using capacity ignores the realities of the test environment. A load cell's compensated temperature range is the zone where accuracy is maintained by design. The operating temperature range is the boundary for hardware survival.

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.
INTERFACE TECH TALK Resistance Output Vs Rated Output

Resistance Output Versus Rated Output

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.

Low Profile Load Cells versus Simple Single Column Load Cells

The Interface LowProfile Load Cell, a pancake design, is dramatically better than the simple single column cell in every respect. The low profile design outperforms the single column design. The overall proprietary Interface LowProfile design is more compact, with all the components bonded to the flexure structure, making it better able to withstand the 100 million-cycle fatigue life. Our standard 1200 “Blue” LowProfile Load Cell is the most popular load cell in the market and is used in testing labs and industry applications worldwide.
INTERFACE 101 STRAIN TESTING

Strain Testing 101

Interface tension and compression load cells are used for strain testing across multiple industries. Learn about strain testing, a very common in general test and measurement applications. Strain refers to the deformation or shape a material experiences due to applied stress. Load cells are used to measure how much a sample or material stretches, compresses, or shears and distorts in response to a force.
