May 4, 2012. Data Translation Inc has announced the release of the DT9838 strain- and bridge-based acquisition module for USB. 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 kS/s simultaneously sampled analog inputs; 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.
“Many strain measurements are taken in the field where power sources are not available,” according to Fred Molinari, president. “Extremely accurate bridge data can now be obtained using a laptop with USB providing the data flow and power needs. Applications such as high speed mechanical tests, in-vehicle testing, and on-site impact measurements can now be done easily with our bridge software. ”
All Data Translation devices include comprehensive driver and software support to get your application up and running quickly. The DT9838 USB data-acquisition module and VIBpoint Framework software application bundle provides a turn-key real time test and measurement solution.
Key design features of the USB-powered DT9838 include simultaneous acquisition with four- 24-bit delta-sigma A/D channels; full-, half-, and quarter-bridge completion; throughput rates up to 52 kS/s per channel; built-in bridge excitation up to 10 V; programmable 100-kΩ ±0.1% shunt resistor per channel; smart sensor TEDS (IEEE 1454.1) compatible;s ynchronized acquisition on up to four DT9838 modules with RJ45 connector; flexible software-programmable trigger and calibration; included drivers and software compatible with Windows XP/Vista/7; and supported via VIBpoint Framework (available as a 14-day trial version). The DT9838 is available installed in a metal connection box with RJ50 connectors, or as board-level OEM version.
