Bently Nevada 200355-02-00-00 Accelerometer, 100 mV/g, IP68

Technical Specifications Breakdown

Key parameters for the 200355-02-00-00 are listed below for quick reference:

Real-World Applications in Harsh Conditions

• Steam turbine bearing monitoring – The wide frequency range (30–600,000 cpm) captures both low-speed and high-frequency vibration signatures.
• Pump and compressor protection – The ±50 g measurement range and 5,000 g shock survivability ensure reliable operation even during transient events.
• Offshore and subsea auxiliary systems – The welded hermetic sealing and stainless steel housing resist corrosion and pressure cycling.

Installation Guidance for Reliable Data

Mount the sensor using the 1/4-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option (02: ¼-28 to M8 x 1.25 BeCu) provides flexibility for different machine interfaces. Allow 2.0 seconds settling time (within 1% of bias) after power-up before taking critical measurements. Use a constant current excitation source between 2 to 20 mA.

Maintenance and Reliability Best Practices

Periodically inspect the electrical connector (2-Pin Mil-C-5015) and cable for signs of wear or corrosion. Because the sensor is hermetically sealed, no internal maintenance is required. Verify output bias voltage (8 to 12 VDC) during routine checks to confirm the sensing element and electronics are functioning correctly. The ceramic shear element offers long-term stability.

Robust Vibration Monitoring for Critical Machinery

As a maintenance engineer, you know that unexpected downtime often starts with undetected vibration. The Bently Nevada 200355-02-00-00 accelerometer delivers the precision and durability needed for continuous monitoring in the most demanding environments. This 200350 series sensor is designed to provide accurate, repeatable data for predictive maintenance programs.

Compatibility and System Integration

The 200355-02-00-00 outputs a standard 100 mV/g signal compatible with most vibration monitoring systems, including Bently Nevada racks and third-party data collectors. The low output impedance (<150 ohms) allows long cable runs without signal degradation. Ensure the power supply provides 18 to 28 VDC excitation.

Selection Guide and Purchasing Advice

When selecting a replacement or new accelerometer, verify the mounting thread, sensitivity, and environmental rating match your application. The 200355-02-00-00 is a proven choice for continuous monitoring in wet, hot, or corrosive areas. Please verify current lifecycle status and availability with AutoDCSTech before ordering. Our team can help confirm compatibility with your existing Bently Nevada system.

Troubleshooting Common Issues

If the output bias voltage drifts outside the 8–12 VDC range, check the excitation voltage and current source. A noisy signal may indicate grounding issues or a failing cable. For no output, verify the connector is fully seated and the power supply is active. Always follow plant safety procedures when working near rotating equipment.
