Using Isolated Signal Conditioners to Protect Equipment and Ensure Measurement Accuracy

Whenever a data acquisition (DAQ) system is moved from the controlled environment of the laboratory to validation testing or the manufacturing floor, measurement inputs can become corrupted. Isolating power sources and sensor signals is the most effective method for eliminating undesirable ground loop currents and associated induced electrical noise to both protect equipment and ensure measurement accuracy. Signal conditioning modules can provide up to four levels of isolation.
