Sound & Vibration DAQ Tools: NI-9231 Module



When measuring noise and vibration levels, our engineers use the NI-9231 sound and vibration module, a CompactDAQ chassis and a Laptop running iTestSystem for data logging and analysis. The NI-9231 module is an updated, higher channel count version of the NI-9234 module.

The NI-9231 is an 8 channel, 51.2 kS/s/channel, -5 V to 5 V, C Series Input Module with IEPE excitation that can be turned on and off, and open/short circuit detection. To increase channel capacity, these modules use 10-32 plug for its sensor input connections. NI provides a PCB Low Noise Coaxial Cable, 10 ft w/10-32 plug to BNC plug to accommodate most standard accelerometer and microphone connections.
