Industry Applications for Reliable Vibration Monitoring

With a frequency range of 30–600,000 cpm and a measurement range of ±50g, it captures both low-speed and high-speed vibration signatures. The IP68 enclosure and welded hermetic sealing make it suitable for washdown zones, high-humidity areas, and outdoor installations where moisture ingress is a concern. By providing accurate, repeatable data, the sensor helps maintenance teams identify bearing wear, imbalance, and misalignment before they cause catastrophic failure.

Installation & Setup Guidance

Mount the sensor using the provided M6x1 adhesive stud mount (included as mounting stud option 11). Ensure the mounting surface is clean, flat, and free of paint or debris. Apply the recommended mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to the 1/4-28 female thread. Use a 2-Pin Mil-C-5015 connector for electrical connection. The top exit connector simplifies cable routing in tight spaces. Power the sensor with an excitation voltage of 18 to 28 VDC and a constant current excitation of 2 to 20 mA. Allow a settling time of 2.0 seconds (within 1% of bias) after power-up before taking measurements.

Maintenance & Reliability

The stainless steel housing and welded hermetic seal protect the ceramic shear sensing element from contaminants and moisture. The sensor can withstand 5,000 g pk shock survivability and operates in 100% relative humidity (condensing, non-submerged). Periodic inspection of the cable and connector for damage is recommended. No internal calibration adjustments are required; the sensitivity is factory set to 100 mV/g ±20%. Verify output bias voltage (8 to 12 VDC) during routine checks to ensure the sensor is functioning correctly.

Facing Unplanned Downtime from Hidden Machinery Vibrations?

Vibration monitoring is critical for predictive maintenance, but selecting the right sensor can be challenging. The Bently Nevada 200350-11-00-CN accelerometer delivers precise, reliable data to help you detect faults early and avoid costly production halts. Designed for demanding environments, this sensor combines rugged construction with proven measurement accuracy.

Compatibility & Integration

The 200350-11-00-CN accelerometer integrates with standard vibration monitoring systems that accept IEPE (ICP®) type sensors. The output impedance is less than 150 ohms, ensuring signal integrity over long cable runs. The discharge time constant is ≥0.3 seconds, suitable for measuring low-frequency vibrations. The electrical isolation (case) is greater than 108 ohms, preventing ground loops. This sensor is a direct replacement for many Bently Nevada legacy accelerometers in similar form factors.

Selection Guide & Purchasing Advice

When selecting an accelerometer, consider the frequency range, sensitivity, and environmental rating. The 200350-11-00-CN offers a broad frequency response and high sensitivity for general-purpose vibration monitoring. For applications requiring country-specific agency approvals, the "CN" option is included. AutoDCSTech stocks this model and can verify current lifecycle status and availability before ordering.

Troubleshooting & Common Issues

If the output bias voltage reads outside 8 to 12 VDC, check the excitation voltage (18 to 28 VDC) and current (2 to 20 mA). A low bias voltage may indicate a damaged sensing element or a short circuit in the cable. Excessive electrical noise (broadband electrical noise is 350 μg from 1–10 kHz) can be caused by poor grounding or proximity to variable frequency drives. Ensure the connector is properly seated and the cable is shielded. If the sensor fails to respond, verify the mounting stud is tight and the mounting surface is clean.
