2 RX1032 OVERVIEW The RX1032 thermocouple measurement instrument is a ruggedized version of the popular EX1000 series, the most advanced, full-featured data acquisition solutions available on the market today. The RX1032 unit provides superior measurement accuracy and repeatability by implementing fully integrated signal conditioning and advanced cold junction compensation (CJC). The RX1032 series uses military grade connectors for power and connectivity while thermocouple and sensor inputs are routed through a protected entry to a screw terminal panel for quick and easy connectivity. The rugged construction of the enclosure enables the measurement system to be mounted on test pylons, in test cells and in other harsh environments. SCALABLE FOR HIGH- SPEED SYNCHRONIZED DATA ACQUISITION The RX10XX family supports easy integration and synchronization of multiple devices through an industry standard IEEE-1588 implementation. Multiple RX1032 instruments can easily be distributed and placed extremely close to the measurement points of interest, reducing the length of analog cable, minimizing errors induced by noisy environments. All measurement data is returned with IEEE-1588 timestamp codes with typical accuracies of <200µS ensuring that the acquired data is tightly correlated across the entire test article. APPLICATIONS Large Scale Engine Test Harsh Environment Health Monitoring HALT / HASS Rocket Motor Reliability Wind Tunnel Test COLD JUNCTION COMPENSATION The heart of any truly accurate thermocouple measurement system is the CJC implementation. The RX1032 combines multiple precision thermistors, a significant thermal mass, and careful parts placement to provide world-class measurement performance. 2
