National Instrument PXIe-4353

The National Instruments PXIe-4353 is a high-accuracy, 32-channel thermocouple input module for PXI Express temperature-measurement systems. It combines 24-bit data acquisition and integrated signal conditioning to support reliable, scalable temperature monitoring in automated test, research, industrial, and environmental applications. ni +1 Designed for demanding multi-point measurements, the PXIe-4353 supports up to 32 thermocouple inputs, with eight cold-junction-compensation channels located close to the terminal connections when used with the appropriate NI terminal block. Two autozero channels provide offset compensation, while open-thermocouple detection helps identify disconnected or faulty sensors. docs-be.ni +1 The module uses three 24-bit delta-sigma ADCs and provides measurement rates of up to 90 S/s across all channels, with a ±80 mV voltage measurement range. Its 300 V bank isolation provides added flexibility when measuring thermocouples installed across distributed equipment or electrically noisy industrial environments. docs-be.ni +1 Suitable for use in PXI Express systems, the NI PXIe-4353 is an excellent choice for applications including thermal characterization, component and product validation, battery and environmental testing, process monitoring, and high-channel-count temperature data logging.
