Core Capabilities & Performance Advantages

High-Fidelity Vibration Measurement
Piezoelectric sensing element with precision charge-to-voltage conversion captures acceleration signals across critical frequency bands (10 Hz to 10 kHz typical), enabling detection of bearing defects, gear mesh anomalies, rotor imbalance, and structural resonances with superior signal-to-noise ratio.

Extended Operating Temperature Range
Rated for -40°C to +125°C continuous operation, the sensor maintains calibration stability in extreme thermal environments including cryogenic pumps, steam turbine casings, exhaust gas compressors, and furnace-adjacent installations where standard sensors fail.

Rugged Industrial Construction
Hermetically sealed stainless steel housing with IP67-equivalent environmental protection resists moisture ingress, chemical exposure, and mechanical shock. Stud-mount design ensures rigid coupling to machinery surfaces for accurate vibration transmission without resonance distortion.

Seamless System Integration
Direct compatibility with Bently Nevada 3300 XL and 3500 series monitoring racks via standard dual-accelerometer input modules. Low-impedance output (100 mV/g typical) eliminates need for in-line amplifiers and supports cable runs exceeding 300 meters without signal degradation.

Factory Calibration & Compliance
Each unit ships with NIST-traceable calibration certificate documenting sensitivity, frequency response, and transverse sensitivity. Meets ISO 20816 vibration severity standards and API 670 machinery protection system requirements for critical service applications.

Reduced Total Cost of Ownership
Early fault detection capabilities extend mean time between failures (MTBF) by 40-60% compared to reactive maintenance strategies. Enables condition-based lubrication scheduling, optimized spare parts inventory, and data-driven overhaul planning that reduces annual maintenance budgets.

Typical Application Scenarios

This accelerometer serves installations demanding continuous vibration surveillance with high reliability and measurement precision:

Turbomachinery & Rotating Equipment
Gas turbines, steam turbines, centrifugal compressors, axial compressors, and turbo-expanders in power plants, LNG facilities, and refinery process units. Monitors bearing condition, rotor dynamics, and casing vibration to prevent blade failures and seal damage.

Critical Process Pumps & Motors
Boiler feed pumps, crude oil transfer pumps, cooling water circulation pumps, and high-voltage induction motors (>500 HP) where unplanned downtime results in production losses exceeding $50,000 per hour. Detects cavitation, hydraulic instability, and electrical faults.

Gearbox & Drivetrain Monitoring
Industrial gearboxes, wind turbine drivetrains, mill drives, and conveyor systems requiring early detection of gear tooth wear, misalignment, and lubrication breakdown. Supports both time-domain and frequency-domain analysis for comprehensive diagnostics.

Reciprocating Machinery
Reciprocating compressors, diesel generators, and large reciprocating engines where crosshead, connecting rod, and crankshaft bearing monitoring prevents catastrophic mechanical failures in remote or offshore installations.

Technical Parameters & Selection Guide

To facilitate engineering design and procurement, we provide standardized specifications with customization options for unique project requirements:

Selection Recommendations: When specifying accelerometers, consider maximum vibration amplitude expected (select sensor range with 2-3× safety margin), dominant frequency content of machinery faults (bearing defects typically 500 Hz - 5 kHz), ambient temperature extremes at mounting location, cable routing distance to monitoring system (low-impedance sensors support >300m runs), and compatibility with existing signal conditioning hardware. For assistance with application-specific selection, provide machinery type, operating speed (RPM), bearing specifications, mounting surface temperature range, and monitoring system model. Our engineers will recommend optimal sensor configuration and mounting accessories.

Frequently Asked Questions (FAQ)

Q: How does the 200350-02-00-00 accelerometer integrate with existing Bently Nevada 3500 monitoring racks?
A: The sensor connects directly to 3500/42M or 3500/44M monitor modules via standard 2-wire shielded cable. The monitor provides 18-24 VDC constant current excitation and processes the low-impedance voltage output. Configuration requires setting sensitivity value (100 mV/g) in Rack Configuration Software and defining alarm setpoints per ISO 20816 or API 670 guidelines. No external signal conditioners needed.

Q: What is the maximum cable length supported without signal degradation?
A: Low-impedance output design supports cable runs exceeding 300 meters (1000 feet) using standard 18-22 AWG shielded twisted-pair cable. For installations beyond 300m, use driven-shield cable or install in-line signal repeaters. Avoid routing sensor cables parallel to high-voltage power lines; maintain minimum 300mm separation to prevent electromagnetic interference.

Q: Can this accelerometer measure low-frequency vibration below 10 Hz?
A: The sensor's usable frequency range extends to approximately 2 Hz (-3 dB point), suitable for monitoring slow-speed machinery (60-600 RPM) and detecting subsynchronous rotor instabilities. For applications requiring DC response or displacement measurement (shaft orbits, rotor position), use Bently Nevada proximity probes in conjunction with accelerometers for comprehensive vibration analysis.

Q: What mounting surface preparation is required for accurate measurements?
A: Mounting surface must be flat (surface finish ≤3.2 μm Ra), clean (remove paint, rust, oil), and perpendicular to vibration measurement axis. Drill and tap 10-32 UNF mounting hole to depth of 6-8mm. Apply thin layer of coupling grease (petroleum jelly or silicone grease) to stud threads and sensor base. Torque sensor to 5-7 Nm (45-60 in-lbs) using calibrated torque wrench. Verify installation by comparing readings with reference sensor.

Q: Is factory recalibration service available for sensors in long-term service?
A: Yes, we offer ISO/IEC 17025 accredited recalibration services with typical turnaround of 10-15 business days. Service includes sensitivity verification across full frequency range, transverse sensitivity check, insulation resistance test, and updated calibration certificate. Recommended recalibration interval is 24-36 months for critical applications or per plant quality management system requirements.

Q: How does this sensor perform in high-vibration environments exceeding 10g RMS?
A: The 200350-02-00-00 is rated for ±50g peak acceleration, equivalent to approximately 35g RMS for sinusoidal vibration. In applications with sustained vibration exceeding 20g RMS (impact mills, crushers, shaker screens), consider industrial-duty accelerometers with extended range (±100g or ±500g) to prevent sensor overload and ensure measurement linearity.
