Product Description
-
The 121M6466 is a wireless triaxial vibration and temperature sensor, part of the Ranger Pro series, designed for continuous condition monitoring of rotating machines in industrial and hazardous environments.
-
It provides vibration data along three axes (X, Y, Z) plus integrated temperature measurement, allowing diagnostic insight including overall values, spectral and demodulation analyses.
-
Communication uses the ISA100.11a wireless protocol (or in some variants, WirelessHART) for robust, encrypted data transmission in operating plants.
-
The device supports over-the-air configuration, lives up to extended battery life, and integrates with condition monitoring systems (e.g. System 1) through gateways.
-
Its rugged construction, sealing, and certifications suit use in harsh and explosive atmospheres.
