Product Description
-
The Bently Nevada 70M403 is a wireless triaxial accelerometer + temperature sensor designed for continuous condition monitoring of rotating machinery (especially bearings, motors, pumps, compressors).
-
It is part of the Ranger Pro wireless sensor family, delivering vibration, temperature, spectral, waveform and demodulation data without wired connections.
-
The sensor supports industrial wireless protocols (such as ISA100.11a or WirelessHART) for robust data transmission in industrial environments.
-
Housed in a rugged stainless steel body with high ingress protection, it is suitable for harsh or hazardous plant environments.
-
Over-the-air configuration, long battery life, and seamless integration with machine condition monitoring systems (such as System 1) make it suitable for predictive maintenance implementations.
