The Essentials of Single-Ended and Differential Voltage Measurement Learn How to Choose Which Method to Apply
Acromag manufactures circuits that amplify, isolate, filter, and convert one signal form to another (signal conditioning). This is essentially what we do, but more simply stated, Acromag manufactures circuits that measure voltage, because that is exactly what we do most of the time. These papers look at important aspects of single-ended and differential voltage measurement, and offer some insight on why it might be better to choose one method over the other. They will also dispel some of the myths and misconceptions of voltage measurement and show how to correctly apply earth ground to these connections. (registration is required).
