More Information

Overview Manuals Applications Communication & Connectivity Compatibility Safety & Compliance

Features:

  • Captures dynamic acceleration, velocity, timebase waveforms, and PeakDemod spectra simultaneously across three orthogonal axes.
  • Integrates 2.45 GHz WirelessHART mesh routing with 128-bit AES encryption to ensure secure, uninterrupted field communication.
  • Combines dynamic triaxial vibration detection with continuous embedded surface temperature monitoring in a single unit.
The Bently Nevada 70M403 is an industrial-grade Ranger Pro triaxial wireless condition monitoring sensor supplied in a brand new, factory-original condition.

This sensor delivers automated vibration and temperature data directly into Bently Nevada System 1 condition monitoring software via HART IP gateways.

Proper orientation during stud mounting with the internal M6 x 1 mm thread is recommended to align the X, Y, and Z orthogonal measurement axes accurately with machine coordinates.

The Bently Nevada 70M403 is covered by a standard 1-year warranty provided by the manufacturer (OEM).
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Provides continuous triaxial vibration and temperature tracking for balance-of-plant equipment skids in oil and gas refineries.
  • Monitors rolling-element bearings in centrifugal pumps, electric motors, cooling tower fans, and blowers within power generation plants.
  • Detects early mechanical faults on remote agitators, centrifuges, and small industrial gearboxes in chemical processing facilities.
  • Operates on the WirelessHART protocol (IEEE 802.15.4 standard) within the license-free 2.45 GHz ISM radio frequency band.
  • Functions as an embedded wireless mesh router to hop measurement packets across neighboring field sensors to the gateway.
  • Transmits dynamic timebase waveforms and frequency spectra to Bently Nevada System 1 software using HART IP protocol interfaces.
  • Seamlessly interfaces with Emerson WirelessHART Gateways including models 1410S, 1410, and 1420 running supported firmware.
  • Supports direct overall vibration and surface temperature data output to third-party PLCs and DCS systems via gateway Modbus connection.
  • Requires Bently Nevada System 1 software version 20.2 or higher for full dynamic waveform analysis and PeakDemod processing.
  • Certified intrinsically safe for North American Class I, Division 1/Zone 0 (AEx ia IIC T4 Ga) hazardous locations.
  • Holds international ATEX and IECEx Zone 0 and Zone 20 intrinsically safe explosion-proof approvals for dust and gas atmospheres.

Description
The Bently Nevada 70M403 Ranger Pro WirelessHART triaxial sensor is engineered to deliver precise dynamic acceleration, velocity, dynamic timebase waveforms, and PeakDemod spectra across three orthogonal axes. By integrating dynamic vibration detection with continuous surface temperature monitoring, it empowers plant operators to optimize machinery availability, detect early bearing failure, and eliminate manual walk-around inspections on balance-of-plant assets.

Deploying the Bently Nevada 70M403 within remote or hazardous industrial environments allows seamless data transmission via HART IP interfaces straight into Bently Nevada System 1 software. The sensor utilizes an IEEE 802.15.4 radio operating at 2.45 GHz with 128-bit AES encryption, acting as both a measurement point and a mesh router to jump data past physical obstructions directly to WirelessHART gateways.

The Bently Nevada 70M403 is housed in a rugged 316 stainless steel and impact-resistant PPS enclosure rated IP67. It is powered by a field-replaceable 3.6V D-cell lithium-thionyl chloride battery that provides up to five years of continuous operation, making it ideal for balance-of-plant equipment skids in oil and gas refineries, power stations, and chemical processing facilities.
