Overview Manuals Applications Operating Environment Monitoring & Control Safety & Compliance

Features:

  • Measures single-axis high-frequency acceleration, velocity, PeakDemod, and surface temperature.
  • Interfaces seamlessly into plant networks via 2.4 GHz ISA100.11a industrial wireless architecture.
  • Engineered with an IP67 316 stainless steel body and powered by an internal replaceable D-cell battery.
Order designation 70M301 specifies the single-axis (uniaxial) accelerometer option within the Bently Nevada Ranger Pro machinery health monitoring line.

Designed to stream continuous machinery diagnostics, this wireless field unit replaces manual route-based measurements with automated spectral data transmissions direct to central gateways.

Initial network provisioning requires using the USB docking station (129M0166) to assign join keys, network IDs, and dynamic sampling schedules prior to site mounting.

Description
The Bently Nevada 70M301 is engineered to deliver comprehensive machine health insights for balance-of-plant equipment equipped with rolling-element bearings, such as industrial pumps, electric motors, blowers, and gearboxes. By combining single-axis piezoelectric accelerometer technology with an integrated surface temperature sensor, the 70M301 enables plant operators to detect early bearing degradation, structural unbalance, and mechanical looseness without installing costly field wiring or cable trays.

Operating as a self-contained, battery-powered field device, the 70M301 eliminates manual walk-around data collection routines by automatically transmitting overall vibration levels, high-resolution timebase waveforms, and PeakDemod spectra directly to central monitoring gateways. Built with a rugged 316 stainless steel chassis and high-impact polymer housing, the 70M301 provides reliable IP67 protection against extreme moisture, dust, chemical exposure, and severe operating environments.

Integrating the 70M301 into your facility allows maintenance engineers to transition from reactive repairs to data-driven predictive strategies, optimizing maintenance schedules and extending asset lifespan across power generation, oil and gas, and heavy manufacturing sites. With built-in wireless routing capability, each 70M301 unit can function as a mesh node to expand field network coverage while maintaining strict 128-bit AES data encryption.
