Description

Ensuring accurate temperature measurements with thermocouples in NI-435x data acquisition systems is where the National Instruments TBX-68T Isothermal Terminal Block shines. This ingenious block minimizes internal temperature variations through its isothermal design, eliminating errors caused by fluctuating temperatures within the terminal block itself. Screw terminals provide secure connections for thermocouple wires, while the block itself caters to 14 temperature channels, making it suitable for various temperature measurement applications. An additional advantage is the built-in cold junction compensation on channel 0, a crucial factor for precise thermocouple readings. The TBX-68T even offers connectivity for digital signals and integrates seamlessly with specific NI digital signal conditioning modules through its 26-pin latched connectors. With its DIN rail mounting capability and shielded cable compatibility, the TBX-68T is a well-rounded solution for researchers and professionals seeking reliable temperature data acquisition using thermocouples. While it might be an older product, the TBX-68T remains a valuable tool for those working with compatible NI-435x systems.

Specifications

  • Compatibility: NI-435x data acquisition products (USB-4350, PCMCIA-4350, PXI-4351, PCI-4351)
