Description
The SCXI-1303 model, with part numbers 182380B-01 and 777687-03, falls under the SCXI & Legacy category. It is designed to be compatible with SCXI-1100/1102/1102B/1102C modules. This model is specifically tailored for high-precision thermocouple temperature measurement applications.
Some of its key features include an isothermal copper plane, a thermistor cold-junction temperature sensor for accurate temperature readings, open thermocouple detection to ensure safety and reliability, and signal ground referencing for improved measurement accuracy. It is equipped with 78 screw terminals and can handle 32 differential inputs, making it highly versatile for various measurement needs.
The thermistor accuracy is noted to be 0.5 °C within the range of 15 to 35 °C and 0.9 °C within the ranges of 0 to 15 °C and 35 to 55 °C. The thermistor output voltage range spans from 1.91 to 0.58 V across the temperature range of 0 to 55 °C, ensuring precise temperature measurement across a broad range.
For software support, the SCXI-1303 requires NI-DAQ driver software and is compatible with LabVIEW and LabWindows/CVI, facilitating easy integration into existing systems. Despite its obsolete status announced by National Instruments, it remains available for purchase and repairs through Apex Waves. Additionally, calibration services are available, with a recommendation for calibration to be performed annually or every two years to maintain optimal performance.
