NI Expands SC Express PXI Sensor Measurement Family With New RTD Module

05/23/2012

• Resistance temperature detector (RTD) module expands measurement capabilities to offer excellent temperature accuracy
• Engineers can use the NI PXIe-4357 RTD module with the NI SC Express family, PXI and the 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 optimized for speed and accuracy

National Instruments announced the NI PXIe-4357 RTD module, the latest addition to its SC Express sensor measurement family for PXI Express. The high-performance module is optimized for temperature measurements with Pt100 RTD sensors for a variety of thermal monitoring applications. The NI PXIe-4357 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 0.09 degrees Celsius. To expand a system’s channel count, engineers can integrate additional NI PXIe-4357 modules or use other SC Express modules to add complementary sensor inputs including thermocouples, strain gages, accelerometers and FBG optical sensors to the same system.

“We designed SC Express to improve measurement accuracy and reliability by integrating signal conditioning and AD conversion into a single module,” said Kevin Schultz, vice president of R&D for National Instruments. “Because SC Express is based on the PXI Express platform, engineers can easily expand their channel counts or synchronize with other measurement or control modules to meet the specific requirements of their test application.”
