Product Description

Overview
The Bently Nevada 134M0389-04 is a high-performance, battery-powered wireless sensor engineered for comprehensive monitoring of rotating machinery. Combining triaxial vibration measurement with digital temperature sensing, this device enables condition-based maintenance without the complexity of wired installations. It is ideal for motors, pumps, compressors, and gearboxes, particularly in challenging or remote environments.

Key Features

Triaxial Vibration Monitoring

• Captures vibration along three axes (vertical, horizontal, axial) for a full 3D analysis

• Z-Axis: Up to 10 kHz frequency response for early detection of bearing defects

• X/Y Axes: Up to 4 kHz for imbalance, misalignment, and structural looseness detection

• Measures acceleration up to ±20 g

Advanced Data Analytics

• High-resolution time waveforms and spectra transmitted to Bently Nevada System 1 software

• PeakDemod algorithm isolates high-frequency metal-to-metal impacts in bearings

Wireless Communication

• ISA100.11a protocol at 2.4 GHz

• Deterministic communication with mesh networking redundancy

• 128-bit AES encryption for secure data transmission

Rugged Industrial Design

• 316L stainless steel enclosure with PPS top for maximum corrosion resistance

• IP67-rated for dust and water immersion protection

• Certified intrinsically safe for Zone 0 / Class I, Div 1 hazardous areas

Technical Specifications

Application Scenarios
The 134M0389-04 excels in monitoring hard-to-access assets, such as cooling tower fans and remote pump stations, where wired installations are impractical. It ensures reliable vibration and temperature tracking in wet, corrosive, or high-vibration environments.
