NI SCXI-1120D Signal Conditioning module

Main features
Strain gauge measurement function: Mainly used to connect strain gauges and convert the tiny strain sensed by the strain gauges into measurable electrical signals. It can precisely measure the change in strain gauge resistance and convert it into the corresponding voltage output for subsequent data collection and analysis.
Multi-channel design: It usually has multiple channels and can simultaneously connect multiple strain gauges to achieve synchronous monitoring of multiple measurement points. This enables the simultaneous acquisition of strain information at multiple positions in complex structures or systems, which is conducive to a comprehensive understanding of the force conditions of the structure.
Signal conditioning function: Amplify, filter and perform other conditioning processing on the input strain gauge signal. By amplifying the weak strain signal, it is made to reach the level range that the data acquisition equipment can accurately measure. Meanwhile, the filter can remove high-frequency noise from the signal, improving the quality and stability of the signal.
High-precision measurement: It features high measurement accuracy and stability, capable of meeting the demands of various high-precision strain measurements. It adopts precise circuit design and calibration technology to ensure accurate and reliable measurement results under different working conditions.
