NI-9235

The NI‑9235 measures dynamic strain on all channels simultaneously, allowing for synchronized, high-speed measurements. This capability is important for applications, such as impact tests, that require comparison across many channels at a particular instant in time. The NI‑9235 includes built-in voltage excitation for quarter-bridge sensors. It also has 60 VDC isolation and 1,000 Vrms transient isolation, providing high‑common‑mode noise rejection and increased safety.

Applications and Use Cases of NI-9235

The NI-9235 C Series Strain Input Module is a C Series module designed for strain and bridge-based measurements. It provides high-accuracy strain acquisition, built-in excitation, and noise-resistant signal conditioning, making it ideal for applications requiring precise measurement of mechanical stress, load, and deformation.
