The DI-740 Series is a family of instruments with the purpose of simplifying self-amplified, transducerbased measurements. Above all, the DI740 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 space 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.
