Isolated Dynamic Signal Test and Analysis System - DE-916 Isolated Dynamic Signal Test and Analysis System - DE-916

The DE-916 High-performance Isolated Dynamic Signal Test and Analysis System is specially designed for accurate capture of transient signals in a strong interference environment. By means of multi-layer shielding technique, DE-916 effectively eliminate electromagnetic radiation and conduction interference, and ensure the accurate measurement of force, pressure, stress, strain, displacement, velocity, acceleration and other physical quantities.
