Multi-Channel Strain Measurement Q.Series A116 and A146 Best in Class

Structural Analysis on All Kinds of Engineered Assemblies Multi-Channel Strain Gauge Application Gantner Instruments specializes in data acquisition of mechanical measurements in automotive, aerospace and civil engineering. The Q.series product range offers best performance in multichannel strain gauge application. Besides the multipurpose modules for strain gauge and inductive bridges in carrier frequency and DC technology, two dedicated modules for multi-channel applications are available. 8-channel strain gauge full, half and quarter bridge 120 Ω and 350 Ω 16-channel strain gauge quarter bridge...

No Deviation with Long Cable Runs Eliminate Data Skew Due to the size of the test specimen, long cables runs are sometimes unavoidable. The Q.series’ 3-wire, quarter-bridge circuit compensates for the drop in excitation voltage, even with cable lengths of up to 120 m. A special method completely compensates zero and sensitivity effects. Data skew in a multi-channel, distributed data acquisition system is one of the major uncertainties during a test program. The Q.series has a built-in time synchronization with a maximum jitter of 1 μs. Minimal Signal Drift Selectable Input Ranges Fatigue tests...
