Ultra-Compact 32-Channel Data Acquisition System Offers a Fully Integrated Solution for Amplified Transducers
AKRON, OH, May 1, 2000 — DATAQ Instruments, Inc. today announced the availability of their Model DI-740 Data Acquisition System for analog, transducer-based measurements. The Model DI-740 is an ultra-compact, portable system combining high-speed sampling, sensor excitation, and signal conditioning for the convenient operation of strain, force, displacement, and similar amplified transducers. Other essential functions the Model DI-740 provides are:
- A flexible range of 16 transducer and 16 general-purpose analog input channels. An external, removable screw terminal strip for each channel speeds signal connection. Built-in 250W shunt resistors simplify measurements with current-output transducers.
- A built-in, isolated 28Vdc excitation for each transducer channel eliminates the need for external excitation sources. Isolation eliminates or greatly reduces errors from common-mode voltages in multiple sensor applications.
- Input ranges of ±1.25 to ±10Vdc full scale, with 16-bit A/D, 250 kHz sampling capability and multiple trigger modes facilitate high-resolution acquisition using a wide range of transducers. Burst mode technology minimizes channel skew.
- Intelligent oversampling and DSP support sophisticated real-time noise reduction, signal averaging, minimum, maximum, or last-point data point detection.
- Standard, bi-directional, enhanced parallel port and optional Ethernet or Universal Serial Bus (USB) provide multiple Plug-and-Play connectivity options without complicated addressing, interrupts, or DMA settings.
- Dual 12-bit, buffered, 250kHz sample/second analog outputs provide programmable voltages for special applications.
- Compact dimensions of only 7.29" × 9.0" × 2.7" (about ¾ the size of a typical laptop computer) permit operation in limited spaces.
The Model DI-740 includes an extensive selection of free software for compatibility with popular third-party packages and languages. Dataq's own WinDaq/Lite and WinDaq Browser (included) support turn-key data recording, playback, and analysis. A Programmer's Software Development Kit (SDK) assists in the development of custom applications using Visual BASIC, C, C++, and other Windows-based languages compatible with ActiveX controls. Drivers for LabView, TestPoint, and HP VEE are available for free download from the Dataq Web site (www.dataq.com). Enhanced WinDaq Pro, and WinDaq Pro+ software are optional.
AVAILABILITY AND PRICING.
The Model DI-740 is available immediately, and is offered in the following configurations:
- DI-740-16-P: 16 transducer and 16 general-purpose channels, EPP parallel I/O interface. Up to 250k sample/second throughput rate.
- DI-740-16-USB: Same as DI-740-16-P, except with a USB interface.
- DI-740-16-EN: Same as DI-740-16-P, except with an Ethernet interface. Maximum throughput rate: 2500 samples/second.
For models with 8 transducer and 16 general-purpose analog input channels, specify DI-740-8-P, DI-740-8-USB, or DI-740-8-EN. Prices range from $2245- $3390, depending on communications interface and number of transducer inputs. WinDaq/Lite, WinDaq Browser, and the Programmer's Software Development Kit (SDK) are included with all models at no additional charge.
