Overview

Product overview

Key product information and technical features.

The PXIe-4353 integrates data acquisition and signal conditioning for thermocouple temperature measurements. Its 32 differential analog input channels provide 24-bit measurement resolution in a PXI Express module.

Two auto-zero channels provide offset compensation, while open-thermocouple detection identifies disconnected thermocouples. The NI TB-4353 isothermal terminal block optimizes thermal conductivity between the thermocouple terminals and cold-junction compensation channels.

  • 32 differential analog input channels for thermocouple measurements.
  • 24-bit temperature input measurement resolution.
  • Analog input voltage range of -80 mV to 80 mV.
  • 300 V bank isolation for analog inputs.
  • Two auto-zero channels for offset compensation and open-thermocouple detection for disconnected sensors.
  • PXI Express bus connection with a DIN front connection.
