Description

Technical Overview

The Bently Nevada 200350-02-00-CN is a high-precision, industrial-grade piezoelectric accelerometer engineered for continuous, real-time vibration monitoring in mission-critical rotating machinery. Manufactured by Baker Hughes (formerly Bently Nevada), a global leader in condition monitoring and predictive maintenance solutions, this sensor delivers exceptional signal fidelity, thermal stability, and long-term reliability under demanding operational environments. Designed specifically for integration into the Bently Nevada 3500/40M and System 1 platforms, the 200350-02-00-CN complies with ISO 2954, ISO 10816, and API 670 standards for vibration measurement in turbomachinery, compressors, pumps, motors, and gearboxes. Its robust stainless steel housing, hermetically sealed construction, and integrated low-noise cabling ensure immunity to electromagnetic interference (EMI), moisture ingress, and mechanical shock—making it ideal for harsh industrial settings including oil & gas refineries, power generation plants, petrochemical facilities, and marine propulsion systems. The accelerometer operates on a constant-current IEPE (Integrated Electronics Piezoelectric) excitation scheme (2–20 mA), enabling seamless compatibility with industry-standard signal conditioners and data acquisition systems. All units are factory-calibrated per ANSI/ISO 16063-21 and supplied with a NIST-traceable calibration certificate. This model is offered in new, unused condition—direct from authorized Baker Hughes distribution channels—with full traceability and compliance documentation.

Detailed Specifications

Key Features

• NIST-Traceable Calibration: Each unit ships with a full calibration report conforming to ANSI/ISO 16063-21, including sensitivity, frequency response, phase linearity, and thermal drift data—ensuring metrological integrity across global operations.
• Hermetic Sealing & IP67 Rating: Dual O-ring sealing and laser-welded housing provide absolute protection against condensation, hydrocarbon vapors, salt spray, and high-humidity environments typical in offshore and refinery applications.
• Low Thermal Drift Performance: Advanced quartz sensing element combined with temperature-compensated electronics maintains amplitude accuracy within ±1% over −40 °C to +100 °C operating range—critical for turbine start-up/shutdown monitoring.
• IEPE Compatibility & Plug-and-Play Integration: Designed for direct connection to Bently Nevada 3500/40M monitors, System 1 software, and third-party DAQ systems without external charge amplifiers—reducing system complexity and failure points.
• Vibration-Resistant Mechanical Design: Rigid 316 SS housing with optimized mass/stiffness ratio minimizes resonance artifacts and ensures stable mounting on high-frequency surfaces such as bearing housings and compressor casings.
• EMI/RFI Immunity: Shielded internal circuitry and grounded housing meet IEC 61000-4-3 (10 V/m radiated immunity) and IEC 61000-4-6 (10 V conducted immunity) standards—essential in electrically noisy substations and VFD-driven motor installations.
• Long-Term Stability: Proven drift performance of <0.5% per year (under normal operating conditions) supports extended calibration intervals and reduces lifecycle maintenance costs.

Applications

• Turbomachinery Health Monitoring: Continuous vibration surveillance of steam/gas turbines, axial/radial compressors, and centrifugal pumps per API RP 670 and ISO 10816-3 guidelines.
• Rotating Equipment Predictive Maintenance: Input sensor for automated fault detection algorithms identifying imbalance, misalignment, bearing degradation, looseness, and resonance in critical assets.
• Power Generation Assets: Real-time monitoring of generator rotors, exciter bearings, and auxiliary feedwater pump trains in nuclear, combined-cycle, and renewable hybrid plants.
• Oil & Gas Infrastructure: Permanent installation on reciprocating compressors, pipeline booster stations, LNG train drivers, and subsea control module support structures.
• Marine Propulsion Systems: Vibration trending on main reduction gears, controllable pitch propellers, and diesel-electric propulsion motors aboard commercial vessels and naval platforms.
• Condition-Based Overhaul (CBO) Programs: Enabling data-driven maintenance scheduling by correlating acceleration spectra with mechanical wear progression models—reducing unplanned downtime by up to 45% (per Baker Hughes field study, 2023).
• Structural Dynamics Testing: Used in laboratory and field modal analysis of rotating equipment foundations, skid-mounted packages, and piping supports to validate finite element models and prevent fatigue failures.
