Request Information
The USB Strain Gage Module (DSCUSB) is a compact, high performance strain gage digital signal conditioner module with USB connectivity. It is aimed at applications which require high measurement accuracy, resolution, and repeatability. The module and sensor are powered by the host USB and will appear as a virtual COM port.

It is ideal for a single sensor application. However, multiple sensors may be connected using a suitable USB hub. The IP50 rated ABS plastic enclosure may be mounted in several ways. DIN rail mounting is available (part# D4).

Software tools are included for quick and convenient interfacing with the device for testing, configuration, calibration, datalogging, and recording. A standard Windows DLL is provided for creating custom applications.

Contact Strainsert for assistance with mounting options, systems integration, or software development.
