Bently Nevada 200355-11-00-00 200350 Accelerometer for Vibration Monitoring

Product Introduction

When industrial plants evolved from reactive repairs to predictive maintenance, vibration monitoring became the cornerstone of reliability. The Bently Nevada 200355-11-00-00 accelerometer from the 200350 series delivers precise vibration data for rotating machinery, helping engineers detect bearing wear, imbalance, and misalignment before catastrophic failure occurs. This sensor transforms mechanical vibration into electrical signals, enabling condition-based maintenance strategies that reduce unplanned downtime.

Technical Specifications Breakdown

The 200355-11-00-00 offers a sensitivity of 100 mV/g ±20%, translating to 10.2 mV/m/s² ±20% for consistent measurement accuracy. Its frequency range spans 30 to 600,000 cpm (0.5 to 10,000 Hz), covering most industrial machinery vibration signatures. The measurement range of ±50g accommodates both normal operation and transient events. With a broadband electrical noise of only 350 μg (3,434 μm/s²) from 1 to 10 kHz, this accelerometer maintains signal clarity even in electrically noisy environments. The output bias voltage sits between 8 and 12 VDC, while excitation voltage ranges from 18 to 28 VDC with constant current excitation of 2 to 20 mA. The discharge time constant is ≥0.3 seconds, and output impedance remains below 150 ohms. Electrical isolation from the case exceeds 10⁸ ohms, preventing ground loop interference.

Industry Applications

This accelerometer excels in continuous vibration monitoring for pumps, compressors, fans, and turbines in oil and gas, power generation, and manufacturing facilities. Its IP68 enclosure rating allows deployment in wet, dusty, or condensing environments without performance degradation. The ceramic shear sensing element provides stable measurements over time, reducing recalibration frequency and lowering total cost of ownership. For predictive maintenance programs, the 200355-11-00-00 delivers the data needed to trend vibration levels and schedule repairs during planned outages.

Installation & Setup Guidance

Mount the accelerometer using the M6x1 adhesive stud mount (option 11). The mounting thread is 1/4-28 female. Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling without damaging the sensor. The top-mounted 2-pin Mil-C-5015 electrical connector simplifies cable routing. Allow a settling time of 2.0 seconds within 1% of bias voltage after power application before taking critical measurements. The operating temperature range spans -65°F to +250°F (-54°C to +121°C), suitable for most industrial environments.

Maintenance & Reliability

The stainless steel housing and welded hermetic sealing protect the internal ceramic sensing element from moisture and contaminants. With shock survivability of 5,000 g peak, this accelerometer withstands accidental impacts during installation or operation. The transverse sensitivity of ≤7% minimizes cross-axis errors. Routine inspection should focus on cable integrity and connector cleanliness. The 100% relative humidity rating (condensing, non-submerged) ensures reliable operation in humid environments.
