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.

When designing systems for automation or maintenance monitoring, capturing high-accuracy force data with a load cell is only the first step.…

Interface's Tech Talk reviews torque wrenches, applications, and FAQs when combining wrenches with reaction torque transducers to validate the tightness of fasteners, bolts, screws, and other mechanical assembly tools used in aerospace, energy, automotive, and manufacturing. A torque wrench is only as reliable as the data supporting it. Combining a torque wrench with high-accuracy torque measurements from torque transducers and advanced instrumentation provides the validation necessary to protect machines, equipment, products, consumers, and workers.
