PXIe-4353

Description

The National Instruments PXIe-4353 PXI Temperature Input Module, with part number 781348-01, is designed to deliver high-performance temperature measurements through its 32 differential thermocouple analog input channels, 2 auto zero channels, and 8 CJC channels. It features 300 V analog input isolation and a built-in TB-4353 isothermal terminal block to ensure maximum conductivity and accurate readings.

This robust module operates in a scanned sampling mode and utilizes a Delta-Sigma ADC type to achieve a maximum sample rate of 90 S/s with a voltage measurement range of ±80 mV. The differential input impedance is rated at 20 mega-ohms, and it offers excellent DC linearity, with a typical value of 20 ppm and a maximum of 60 ppm.

Enhanced features include software-selectable open thermocouple detection, which helps in identifying disconnected thermocouples, and varying input current levels with 17 Nano-amperes when OTD is enabled and 400 Pico-amperes when disabled. This level of detail and customization ensures that the PXIe-4353 module can be finely tuned to meet the needs of complex and sensitive temperature measurement tasks.
