The PXIe‑4353 is a thermocouple input module that provides integrated data acquisition and signal conditioning for temperature measurements. The PXIe‑4353 includes increased accuracy and synchronization features for scalable measurement systems from low‑ to high‑channel counts. The high accuracy is attributed to the NI TB‑4353 isothermal terminal block that optimizes thermal conductivity between the thermocouple terminals and the cold-junction compensation (CJC) channels. The PXIe‑4353 has two auto zero channels for offset compensation as well as open thermocouple detection to identify disconnected thermocouples.
Takes measurements from thermocouples and resistance temperature detectors (RTDs) for PXI systems.
The PXI Temperature Input Module features up to 32 channels of analog temperature measurements. This module support both high-speed and high-resolution modes. You can program channel configurations and scale measured data into engineering units. Some models include autozero channels for offset compensation as well as open thermocouple detection to identify disconnected thermocouples, while others support 2-, 3-, or 4-wire resistance temperature detector (RTD) measurements.
