NI-9234

The NI-9234 is a 4-channel C-series dynamic signal acquisition module capable of high-precision audio measurement for integrated circuit piezoelectric (IEPE) and non-integrated circuit piezoelectric (IEPE) sensors equipped with NICompactDAQ or NICompactRIO systems. The NI-9234 has a 102dB dynamic range and is capable of software-optional integrated circuit (IEPE) signal conditioning for acceleration sensors and microphones. The four input channels are digitized simultaneously at a rate of up to 51.2kHz per channel with the help of a built-in anti-aliasing filter that automatically adjusts the sampling rate.
NI – 9234 can be measured from the integration of electronic pressure electric (IEPE) and the IEPE sensors signals, such as the accelerometer, turn speed meter and proximity agent injection. The NI-9234 is also compatible with smart TEDS sensors. NI – 9234 provides a wide dynamic range, and integrated with software optional AC/DC coupling and IEPE signal disposal. The input channel synchronizes the measurement signal. Each channel also has a built-in anti-aliasing filter that automatically adjusts to the sampling rate.
