Request Information
Digital Strain Gage Modules (DCell) are compact, high performance strain gage digital signal conditioner modules. They are aimed at applications which require high measurement accuracy, resolution, and stability. The internal signal conditioner reduces interference in noisy environments and allows for longer cable runs. The module and sensor may be powered by a typical DC power supply and communicates using standard or custom bus communications and protocols. Outputs include RS-485 and CAN. Available protocols include ASCII, CAN, and Modbus.

The modules may be mounted inside of the Strainsert sensor body in either a single bridge, dual bridge, or biaxial configuration.

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

Contact Strainsert Engineering for assistance with custom solutions, systems integration, or software development.
