The Somat eDAQlite Bridge Layer (ELBRG) offers four simultaneously sampled low-level differential analog inputs through independent connectors.
The Somat eDAQlite Bridge Layer (ELBRG) offers four 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 ELBRG 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 embedded software tools. Four shunt calibration resistors per channel are also included, with software selectable shunt direction.
