Data Translation announces DT9837B for portable sound & vibration
April 18, 2010 Data Translation announced the DT9837B ultra-high throughput USB data acquisition module for portable noise and vibration measurement. The highly accurate front-end design of the USB-powered DT9837B allows users to simultaneously sample up to four 24-bit, IEPE sensor inputs at a sampling rate of up to 105.4 kHz samples per channel.This rugged small module is self-powered via the USB connection to a PC or laptop, no external power supply is needed, making the DT9837B ideal for portable sound and vibration field measurement and analysis applications. In addition, four modules can be triggered simultaneously for perfectly synchronized measurements on up to 16 input channels.Key Features of the DT9837B:
4 Simultaneous 24-bit Delta-Sigma analog inputs for high resolution measurements.
IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4mA current source ensures greater accuracy.
Up to 105.4 kHz sampling rate per channel offers previously unachievable results.
Data streams matched in time with synchronous tachometer input measurements.
Expand to 16 IEPE input channels, using 4 modules precisely synchronized.
Optional signal sampling ranges of ±10V with software selectable programmable gains of 1 and 10 offers even greater resolution.
Single-value and continuous conversion modes provide input flexibility.
Totally self-powered through USB.
Rugged enclosure for noise immunity.
Includes comprehensive software CD for making measurements quickly and easily.
Pricing and AvailabilityThe DT9837B is priced at $1795 and ships immediately.The DT9837B offers previously unachievable accuracy with a 4mA excitation current source for each channel, allowing the use of accelerators double the span, states Fred Molinari, President and CEO. Additionally, our tachometer input design is based on a maximum frequency of 1MHz and a minimum pulse width of 0.4 µs, resulting in greater reading flexibility and more accurate rotary measurements, all achieved while still fully operating off portable USB power.About The CompanyData Translation Inc. is a leading designer, manufacturer, and provider of USB data acquisition (DAQ) modules, USB and Ethernet (LXI) measurement instrumentation, and software solutions for the test and measurement market.
