Interface 101 series details high-fidelity (Hi-Fi), a term referencing how accurately a measurement system reproduces the characteristics of a physical input. Load cell users may require a high-fidelity system where the digital output precisely reflects the mechanical force applied to the sensor. This integrity must be maintained throughout the entire signal chain, from the physical deformation of the strain gage to the final data output. Hi-Fi is very important in aerospace, additive manufacturing, and product efficiency such as lightweighting.

Interface analog-to-digital converters (ADCs) are vital in advanced force measurement systems. These devices connect the analog output of force transducers to digital inputs for data acquisition and analysis. Interface load cells, torque transducers, and multi-axis sensors produce a small analog voltage proportional to the applied force. This signal needs careful conditioning and conversion before it can be used for logging, viewing, and analysis. The ADC carries out this important conversion, changing the continuous analog voltage into a discrete digital representation.
