4-Channel Portable Strain- and Bridge-Based DAQ

DT9838 - USB powered DAQ for Strain Sensors

The DT9838 offers high-speed performance in a compact form factor for applications including strain, load, pressure, and other bridge-based measurements. The bus-powered module removes the need for an external power supply and offers 24-bit resolution; direct connectivity; 52.7 kS/s simultaneously sampled analog inputs for dynamic measurements; full-, half-, and quarter-bridge completion; up to 10 V internal excitation; transducer electronic data sheet (TEDS) smart sensor compatibility and channel expansion using the RJ45 synchronization connector to synchronize up to four DT9838 modules.
