ADU70

USB 24-bit Load Cell interface with 5.000V excitation

Description

The ADU70 USB Load Cell Interface enables wheatstone bridge measurements with 24-bit resolution at sample rates up to 150Hz. The internally isolated excitation voltage of 5.000V is suitable for most wheatstone bridge based load cells. This low-cost USB Load Cell Interface is easy to use with VB, and Visual C++ or .NET via standard HID drivers included with Windows. A mini-driver (DLL) is also provided allowing control using standard ASCII commands using familiar readfile, writefile commands. The ADU70 includes a 10' USB cable and is available in a flange mount enclosure with a DIN rail mount option.
