SoMat eDAQ Bridge Layer
The SoMat eDAQ Bridge Layer (EBRG) offers 16 simultaneously sampled, low-level differential analog inputs through independent connectors. An extremely versatile layer, the Bridge Board works with both amplified and unamplified transducers, including strain gauges, accelerometers, pressure transducers, load cells, and other general analog signals.
The EBRG provides excellent strain gauge conditioning with support for 1/4-, 1/2-, and full-bridges. Automatic balancing and gain settings--as well as software selectable sample rates, excitation, and digital filtering--simplify the set-up of a strain channel. There are several calibration options, including defined value, external, multipoint and shunt calibrations with imbedded software tools. Four shunt calibration resistors per channel are also included, with software selectable shunt direction.
The EBRG is available with an optional Analog Out. Calibration files, directly compatible with popular simulation software, scale the analog outputs to engineering units.

Analog Out (EBRG-AO)
The eDAQ Bridge Layer (EBRG-AO) analog outputs are conditioned output signals that can be used in the creation of time-domain lab durability tests. When setting up the laboratory simulation, the SoMat eDAQ system is brought into the lab with the component or vehicle. This practice is highly recommended, as it ensures that all of the transducer instrumentation and properties are identical for the lab simulation as they were for the field data collection. Instead of being recorded, the analog out signals are sent as time series data for the test rig to analyze. The controller can then develop drive files that are played into the test rig, reproducing exact field dynamics in the lab.
