NI-9232

The NI‑9232 can measure signals from integrated electronic piezoelectric (IEPE) and non‑IEPE sensors such as accelerometers, tachometers, and proximity probes. The NI‑9232 is also compatible with smart TEDS sensors. The NI‑9232 incorporates software-selectable AC/DC coupling, IEPE open/short detection, and IEPE signal conditioning. The input channels simultaneously measure signals. Each channel also has built-in anti-aliasing filters that automatically adjust to your sample rate. When used with NI software, this module provides processing functionality for condition monitoring such as frequency analysis and order tracking.
