Description

The Bently Nevada 133819-02 is a high-precision accelerometer from Emerson’s Bently Nevada 3300 XL series, engineered for critical vibration monitoring in industrial machinery. Designed for permanent installation on rotating equipment, this rugged sensor captures high-frequency vibration data essential for detecting bearing defects, gear mesh issues, and early-stage mechanical failures. The 133819-02 features an integrated electronic piezoelectric (IEPE) design with 100 mV/g sensitivity, delivering exceptional signal-to-noise ratio across a broad frequency range. Its hermetically sealed, corrosion-resistant 316L stainless steel housing withstands extreme environments from offshore platforms to high-temperature turbine decks, while the integral 10-meter cable (suffix -02) ensures reliable signal transmission in electrically noisy plants.

As a cornerstone of predictive maintenance programs, the Bently Nevada 133819-02 interfaces seamlessly with Bently Nevada 3500 series monitors and System 1® software, enabling real-time machinery health analytics. Its wide temperature tolerance (-55°C to +120°C) and intrinsic safety certifications make it indispensable for hazardous areas. The sensor’s low-profile design minimizes mass loading effects, preserving measurement accuracy on thin-skin applications like compressor casings or motor end-bells.

Technical Specifications

Main Features and Advantages

High-Fidelity Sensing: Wide 10 kHz bandwidth captures high-frequency events like bearing spall or gear tooth impacts. Low noise floor (0.003 g/√Hz) reveals subtle defects. Hermetic sealing prevents moisture ingress in washdown environments.

Extreme Durability: Machined 316L stainless steel housing resists H₂S corrosion and chemical splash. Integral armored cable withstands crushing forces (1,000 N lateral load). Survives steam cleaning (IP69K) and thermal cycling.

Simplified Integration: Voltage-mode output eliminates external signal conditioners. Integral 10-meter cable reduces junction points. ATEX/IECEx Zone 0 certification allows direct installation in explosive atmospheres.

Application Field

The Bently Nevada 133819-02 excels in high-risk industrial sectors:

Oil & Gas: Monitors pump bearing health in offshore platforms and compressor blade-pass vibration in LNG trains.

Power Generation: Detects turbine blade resonance and generator stator core looseness.

Petrochemical: Surveils reactor agitator gearboxes and FCCU air blowers.

Marine: Measures propulsion engine vibration on DNV-GL certified vessels.

Mining: Guards critical assets like SAG mill pinion bearings and conveyor drives.
Its 10 kHz bandwidth is critical for detecting early-stage rolling element bearing defects (BPFO/BPFI frequencies) in high-speed machinery.
