The DI-740 Series is a family of instruments with the purpose of simplifying self-amplified, transducer-based measurements. Above all, the DI-740 was designed to offer convenience by providing its own isolated field excitation per channel and data acquisition in one instrument.
Use the DI-740 for amplified transducers such as those used to measure pressure, vacuum, load/force, torque, displacement, acceleration, position and more. Examples of these applications include stamping presses, hydraulic systems, pump and compressor systems, automotive tests, rolling mills, liquid-level sensing and injection molding.
The DI-740 is ideal for both desktop and portable computer users who need a flexible data acquisition solution for measurements using self-amplified transducers. Its super compact size allows it to be used in areas with limited spaces such as machinery, automobiles, aircraft, the shop floor, etc. Its standard port design allows it to be used with laptop or desktop PCs and eliminates the need to open computers, or worry about base address, interrupt or DMA configurations.
The DI-740 features a per-channel programmable gain range of 1, 2, 4 and 8. Each DI-740 input channel can be programmed to measure ±10, ±5, ±2.5, or ±1.25 VFS, respectively. In addition, the DI-740 has a built-in 250Ohm shunt resistor per channel for process-current mode transducers. With its isolated 28 VDC power supply per channel, it allows you to connect virtually any model voltage or current output, self-amplified transducer. Isolation eliminates or greatly reduces errors caused by common mode voltages when multiple transducers are connected.
DI-740 instruments are available with printer port, Ethernet, and universal serial bus (USB) communication interfaces. All instruments have a 25-pin male printer port connector for EPP, bi-directional, or standard mode parallel port communication with your PC. (Standard mode not available on USB or EN models.) Options add Ethernet communication capability with a 10base-T Ethernet connector, or a USB port for universal serial bus communication. The optional communication interfaces cannot be used concurrently with the printer port.
Connect to DC or near-DC signals like static-pressure and loads or other slow process variables. Sample rates well into the sub-Hertz range are possible. Use sample rates as high as 250,000 Hz for high speed applications such as modulated DC drives and other AC waveform situations.
The DI-740-16 Series features 32 channels (16 signal-conditioned channels and 16 general-purpose channels). Each of the 16 signal-conditioned channels provides its own isolated power supply for transducer excitation. Thus, the DI-740 provides all the electronics needed for measurements using amplified transducers. (The DI-740-8 Series features 24 channels: 8 signal-conditioned and 16 general-purpose.)
DI-740 instruments apply 16-bits (14-bits when used with WinDaq Software) of resolution to your measurement task, yielding resolutions as fine as 1 part in over 32,000.
All instruments connect in seconds to your PC's parallel port, Ethernet connector, or USB port using the supplied cable. The DI-740 features a removable terminal strip per channel to simplify transducer connections to the instrument.
WinDaq/Pro+ is free with the purchase of every DI-740 instrument. WinDaq/Pro features a sample rate that is only limited by the maximum sample rate of the hardware and allows you to tailor sample different channels at different rates. This is done by entering a sample rate divisor value (1 to 255) for each channel. Click here for more information regarding this offer.
WinDaq Waveform Browser, our unrestricted playback and analysis software for Windows, is distributed free of charge. Use it to review, measure, compare and analyze the waveform file after it has been recorded by WinDaq/Lite, WinDaq/Pro or WinDaq/Pro+ waveform recording software. WinDaq software products support up to 14 bits of resolution.
