Bently Nevada 200355-12-00-00 Accelerometer: 100 mV/g ±20% for Vibration Monitoring

Accelerometer Overview for Cost-Effective Vibration Monitoring

Industrial vibration monitoring directly impacts operational costs. Unplanned downtime from undetected machinery faults can exceed $50,000 per hour in continuous process industries. The Bently Nevada 200355-12-00-00 accelerometer offers a reliable, solution to reduce these risks without over-investing in unnecessary features.

This 200350 series accelerometer delivers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), providing accurate vibration data for early fault detection. Its robust design, including stainless steel housing and welded hermetic sealing, ensures long service life in demanding environments, lowering total cost of ownership.

Technical Specifications Breakdown

Key parameters for the 200355-12-00-00 are listed below for quick reference:

Real-World Applications for ROI

Pump and Compressor Monitoring: The wide frequency range (30-600,000 cpm) and ±50 g measurement range allow detection of both low-speed imbalance and high-frequency bearing faults. Early identification reduces repair costs by up to 40% compared to run-to-failure strategies.

Harsh Environment Installations: With an IP68 enclosure rating and operating range from -65°F to +250°F, this accelerometer performs reliably in outdoor or high-temperature areas, eliminating the need for expensive protective enclosures.

Turbomachinery Protection: The high transverse sensitivity (≤7%) and amplitude linearity (±1%) ensure accurate data for critical assets, minimizing false alarms and unnecessary maintenance shutdowns.

Installation Guidance for Optimal Performance

Mount the accelerometer using the 1/4-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The M8x1.25 adhesive stud mount (option 12) simplifies installation on curved or irregular surfaces. Ensure the mounting surface is clean and flat to maintain the mounted resonant frequency of 1500 kcpm (25 kHz).

Connect the 2-Pin Mil-C-5015 electrical connector with an excitation voltage of 18 to 28 VDC and constant current of 2 to 20 mA. Allow 2.0 seconds settling time (within 1% of bias) before taking measurements to ensure data accuracy.

Maintenance and Reliability Considerations

Inspect the accelerometer and cable periodically for physical damage or corrosion, especially in condensing humidity environments (100% relative humidity, non-submerged). The welded hermetic sealing and stainless steel housing provide protection, but regular visual checks prevent unexpected failures.

The discharge time constant (≥0.3 sec) supports stable low-frequency measurements. Verify output bias voltage (8 to 12 VDC) during routine calibration to confirm sensor health.

Compatibility and Integration

The 200355-12-00-00 integrates with standard vibration monitoring systems that accept 100 mV/g sensitivity inputs. Its electrical isolation (>108 ohms) ensures signal integrity in noisy industrial environments. The top-mounted 2-pin connector simplifies wiring in tight spaces.

Selection Guide and Purchasing Advice

When selecting an accelerometer, match the sensitivity and frequency range to your machinery's operating speed. Contact AutoDCSTech to verify current lifecycle status and availability before ordering. Our team can help confirm compatibility with your existing Bently Nevada systems.

Troubleshooting Common Issues

If output bias voltage drifts outside 8-12 VDC, check the excitation voltage (18-28 VDC) and constant current supply (2-20 mA). High electrical noise may indicate grounding issues; verify isolation exceeds 108 ohms. For erratic readings, inspect the mounting torque and thread condition.
