Last week, Data Translation announced another in its long line of USB data-acquisition modules, the DT9829. What's different about this system is its ability to accept any kind of sensor on any of its eight channels. Thus, you can mix and match voltage current, resistance, temperature, strain, and other sensors in one system. Available in an enclosure or as an OEM unit, the DT9829 is bus powered.
At this point, you may be thinking "Sensors can use two, three, four, or six wires. How do they connect?" I asked Data Translation president Fred Molinari, who explained that the instrument's terminal strip has up to eight inputs where each channel has a pair of connections, plus it has provisions for a current source -- think RTD -- and a voltage source for bridge sensors such as strain gauges. The case has icons for many popular sensors to help you connect them to the terminal strip.
