National Instruments Aust & NZ  announces the release of the new NI PXIe-4357 RTD module, the latest addition to its SC Express sensor measurement family for PXI Express.

The new resistance temperature detector (RTD) module expands measurement capabilities to offer excellent temperature accuracy. Engineers can use the NI PXIe-4357 RTD modules with the NI SC Express family, PXI and LabVIEW Real-Time Module to create reliable sensor measurement systems that scale from tens to thousands of channels.  
SC Express combines data acquisition and signal conditioning in a single PXI module for high-performance, reliable sensor measurements optimised for speed and accuracy. The high-performance RTD module is optimised for temperature measurements with Pt100 RTD sensors for a variety of thermal monitoring applications.

The NI PXIe-4357 RTD module integrates sensor-specific signal conditioning with 24-bit ADCs to sample all 20 channels at 100 S/s and offers typical accuracies of up to 0.09ºC. Engineers can integrate additional NI PXIe-4357 modules or use other SC Express modules to expand a system’s channel count, adding complementary sensor inputs including thermocouples, strain gages, accelerometers and FBG optical sensors to the same system.

Kevin Schultz, vice president of R&D for National Instruments explains that the SC Express was designed to improve measurement accuracy and reliability by integrating signal conditioning and AD conversion into a single module.

Key features of NI PXIe-4357 RTD Modules:  
  • Offers 20 channels that integrate 24-bit delta-sigma analogue-to-digital converters with antialiasing and low-pass filters
  • Acquires at sampling rates up to 100 S/s/ch and accuracies up to 0.09ºC
  • Delivers reliable measurements with full support on LabVIEW Real-Time
  • Synchronises with other members of SC Express family within the same PXI chassis, across chassis or across facilities
