Bently Nevada 200355-13-00-00 Accelerometer: 100 mV/g Vibration Sensor

Reliable Vibration Monitoring with the Bently Nevada 200355-13-00-00

When unexpected machinery downtime disrupts production, accurate vibration data becomes critical. The Bently Nevada 200355-13-00-00 accelerometer from the 200350 series delivers precise measurements to help you detect early signs of bearing wear, imbalance, or misalignment. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, this sensor captures both subtle and severe vibration events across a wide frequency spectrum from 30 to 600,000 cpm (0.5–10,000 Hz).

Built for harsh environments, the 200355-13-00-00 features a stainless steel housing, welded hermetic sealing, and an IP68 enclosure rating. It withstands 100% relative humidity (condensing, non-submerged) and operates from -65°F to +250°F (-54°C to +121°C). The magnetic base kit (Mounting Stud option 13) simplifies temporary or semi-permanent installation on ferrous surfaces, making it ideal for route-based data collection or spot-checking critical assets.

Solving Common Vibration Monitoring Challenges

Many industrial facilities struggle with sensor drift, electrical noise interference, and mounting inconsistencies. The 200355-13-00-00 addresses these pain points directly. Its ceramic shear sensing element provides excellent transverse rejection (≤7%) and amplitude linearity (±1%), ensuring accurate readings even in the presence of cross-axis vibration. The low broadband electrical noise (350 μg from 1–10 kHz) means you can trust the data for early fault detection without false alarms from electrical interference.

The magnetic base kit (option 13) eliminates the need for drilling or adhesive mounting, reducing installation time and allowing quick relocation between measurement points. This flexibility is especially valuable for temporary monitoring campaigns or troubleshooting intermittent issues.

Industry Applications

This accelerometer excels in predictive maintenance programs across rotating machinery: pumps, fans, motors, compressors, and gearboxes. In a typical paper mill, for example, the 200355-13-00-00 can be magnetically attached to bearing housings on dryer rolls or press sections to monitor for developing faults. The wide frequency range captures both low-speed imbalance and high-frequency bearing defects, while the IP68 rating withstands washdown environments.

In oil and gas facilities, the sensor's 5,000 g shock survivability protects against accidental impacts during installation or maintenance. The 2.0-second settling time allows quick stabilization after power-up, minimizing data collection delays during route-based surveys.

Installation and Setup Guidance

For optimal performance, mount the 200355-13-00-00 on a clean, flat ferrous surface using the magnetic base kit. Apply the specified mounting torque of 2–5 ft-lb (2.7–6.8 N-m) to ensure proper coupling without over-tightening. Connect the 2-pin Mil-C-5015 connector to a compatible data collector or monitoring system that supplies 18–28 VDC excitation with 2–20 mA constant current. Allow at least 2 seconds for the output bias voltage to stabilize before taking measurements.

When installing in high-humidity or condensing environments, ensure the connector is properly sealed to maintain the IP68 rating. The top-exit connector design simplifies cable routing in tight spaces.

Maintenance and Reliability

The welded hermetic seal and stainless steel construction provide long-term reliability in corrosive or wet conditions. No routine maintenance is required beyond periodic inspection of the cable and connector for damage. Verify the magnetic base retains adequate holding force before each use. If sensitivity or bias voltage drifts outside specified tolerances, replace the sensor to maintain measurement accuracy.

Selection Guide and Purchasing Advice

Before ordering the Bently Nevada 200355-13-00-00, confirm your data collection system supports the 100 mV/g sensitivity and 18–28 VDC excitation voltage. This model includes the magnetic base kit (option 13) and has no agency approvals (option 00).
