24 CHANNEL HIGH PERFORMANCE BRIDGE MEASUREMENTS OVERVIEW The RX0124 is part of VTI’s RX0XXX family of rugged instruments with built in sensor signal conditoning. The RX0124 is designed to address all strain/bridge measurement requirements for use in a harsh test cell enviornment. All connections and operations are designed for rugged operation by using Mil-Grade connections for all inputs. The RX0124 is capable of: • 24 simultaneous sampling ADC’s and Bridge signal conditioning Bridge Completion Selections of 120Ω, 350Ω, and 1000Ω • Ethernet interface for simplified scalability and IEEE...

24 CHANNEL HIGH PERFORMANCE BRIDGE MEASUREMENTS SELF-TEST DIAGNOSTICS The RX0124 has a built in health monitoring capability. This allows for close monitoring of functions, including: • Signal Conditioning & ADC - Voltage Excitation, Current Excitation, and Bridge Completion • Input Voltage Ranges • Volatile and Non-Volatile Memory of the System • Internal TEDS memory • Closed loop end-to-end self-calibration to help ensure maximum accuracy over time and temperature • Loop/Lead wire resistance • Open and short circuit self-test diagnosis • Gage integrity verification B U I LT- I N S I G N A...

24 CHANNEL HIGH PERFORMANCE BRIDGE MEASUREMENTS ONE INSTRUMENT WITH SOFTWARE CONFIGURED PERSONALITIES The RX0124 gives users the ability to address a wide range of strain gage measurement capabilities with a single instrument. The RX0124 can be configured to provide highly accurate static strain measurements using constant voltage bridge excitation at a wide range of sample rates. For 2 wire dynamic strain gage measurements, the instrument can be configured to provide constant current excitation with AC coupling to capture data at rates of up to 128Ksa/sec to properly capture dynamic strain...
