NI-9234

The NI‑9234 can measure signals from integrated electronic piezoelectric (IEPE) and non‑IEPE sensors such as accelerometers, tachometers, and proximity probes. The NI‑9234 is also compatible with smart TEDS sensors. The NI‑9234 delivers a wide dynamic range and incorporates software-selectable AC/DC coupling 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.
