National Instruments is launching the NI PXIe-4357 RTD module as the latest addition to its SC Express sensor measurement family for PXI Express. The high-performance module is optimised 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 100S/s and offers typical accuracies of up to 0.09degC. 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.
Kevin Schultz, Vice President of R&D for National Instruments, says: "We designed SC Express to improve measurement accuracy and reliability by integrating signal conditioning and AD conversion into a single module. Because SC Express is based on the PXI Express platform, engineers can easily expand their channel counts or synchronise with other measurement or control modules to meet the specific requirements of their test application."
The NI PXIe-4357 RTD module:
- 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 100S/s/ch and accuracies up to 0.09degC
- Is claimed to deliver the industry’s most 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
