The strain gauge data logger OM-CP-BRIDGE-101A is a battery-powered, stand-alone device that measure and record voltage signals from strain gauges, load cells and other low level dc sources. This compact, unit is perfect for monitoring stress, torque, strain, pressure and data from many other sensors/transducers.

The OM-CP-BRIDGE101A offers a multiple start/stop function, ultrahigh speed download capability, 1 million reading storage capacity, optional memory wrap, battery life indicator, optional password protection, programmable alarms and more.

Data retrieval is simple. Plug it into an available USB port and the easy to use Windows software does the rest. The software converts your PC into a real time strip chart recorder. Using the Windows® software, starting, stopping and downloading from the OM-CP-BRIDGE101A is simple and easy. Graphical, tabular and summary data is provided for analysis and data can be viewed in V, mV and µV. The data can also be automatically exported to Excel® for further calculations. The storage medium is non-volatile solid state memory, providing maximum data security even if the battery becomes discharged. Its small size allows it to fit almost anywhere. 

The OM-CP-BRIDGE101A was designed with our customers in mind. There are free firmware upgrades for the life of the product so that data loggers already deployed in the field can grow with new technological developments. Units do not need to be returned to the factory for upgrades. The user can do this automatically from any PC.
