Starting at less than £107 per channel, these modules are said to be the lowest-cost, measurement-class strain modules available on the market for high-channel-count structural test
National Instruments has announced the new SCXI-1521 and SCXI-1521B strain measurement modules, two devices that it says set a new price point for measurement-class structural test.
The SCXI-1521 and SCXI-1521B modules are 24-channel, quarter-bridge strain gauge input modules optimised for low-cost structural test.
The SCXI-1521 supports 120 ohm strain gauges per channel while the SCXI-1521B supports 350 ohm gauges.
Both modules also include 10Hz filters, programmable null and shunt calibration, amplification and programmable excitations from 0 to 5V.
The SCXI-1521 and SCXI-1521B modules work with all SCXI signal conditioning chassis and can be used with the new 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.
In addition, the SCXI-1521 and SCXI-1521B modules work seamlessly with NI Labview 7.1 and NI-DaqMX 7.3 measurement services software to reduce overall system setup and application development time.
