NATIONAL Instruments has released the SCXI-1521 and SCXI-1521B strain measurement modules.

They are 24-channel, quarter-bridge strain gauge input modules optimised for low-cost structural testing. The SCXI-1521 supports 120Ω strain gauges while the SCXI-1521B supports 350Ω gauges. Both include 10Hz filters, programmable null and shunt calibration, amplification and programmable excitations from 0V to 5V.

The modules work with all SCXI signal conditioning chassis and can be used with the plug-and-play SCXI-1600 USB data acquisition module for portable applications. Engineers can add other modules to the same SCXI chassis for pressure, temperature and a variety of other sensor and high-voltage measurements.

The modules also work seamlessly with NI LabVIEW 7.1 and NI-DAQmx 7.3 measurement services software to reduce overall system setup and application development time.
