NI-9211

The NI‑9211 includes anti-aliasing filters, open-thermocouple detection, and cold-junction compensation for high-accuracy thermocouple measurements. The NI‑9211 features NIST‑traceable calibration and a channel‑to‑earth ground double isolation barrier for safety, noise immunity, and high common-mode voltage range.

Applications and Use Cases of NI-9211

The NI-9211 C Series Thermocouple Input Module is a C Series module designed for high-accuracy thermocouple temperature measurement. It features built-in cold junction compensation (CJC), channel-to-channel isolation, and high noise rejection, making it suitable for applications requiring precise and reliable temperature acquisition in demanding environments.
