200350-01-00-CN | Bently Nevada 100 mV/g Accelerometer

What Is the 200350-01-00-CN?

When rotating machinery begins to show subtle vibration changes, the 200350-01-00-CN from Bently Nevada provides the precise data needed to diagnose developing faults. This accelerometer is part of the 200350 series, designed for continuous vibration monitoring in critical industrial applications. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both low-level and high-amplitude vibration signals accurately.

Key Features & Technical Specs

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%) ensures consistent output across units.
• Frequency Range: 30–600,000 cpm (0.5–10,000 Hz) covers most rotating machinery fault frequencies.
• Measurement Range: ±50g allows monitoring of normal operation and transient events.
• Output Bias Voltage: 8 to 12 VDC provides a stable baseline for signal processing.
• Excitation Voltage: 18 to 28 VDC with constant current 2 to 20 mA simplifies integration with standard condition monitoring systems.
• Enclosure Rating: IP68 enables operation in wet, condensing environments without submersion.
• Temperature Range: -65°F to +250°F (-54°C to +121°C) suits extreme process areas.
• Shock Survivability: 5,000 g pk ensures robustness in harsh machinery.

One distinctive spec is the mounted resonant frequency of 1500 kcpm (25 kHz), which extends the usable frequency range well beyond typical accelerometers, making it ideal for high-speed machinery analysis.

Real-World Applications

In a petrochemical plant, a pump operating at 3,600 RPM began showing erratic vibration. The 200350-01-00-CN mounted on the bearing housing detected a 1× RPM increase with 0.5g amplitude, trending upward over two weeks. This early warning allowed scheduled maintenance before bearing failure, avoiding unplanned downtime. Other common applications include monitoring fans, compressors, turbines, and gearboxes where early fault detection reduces repair costs.

Installation & Mounting

The accelerometer features a 1/4-28 female mounting thread and requires a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Use the included ¼-28 to M6 x 1.00 stainless steel stud for metric installations. Ensure the mounting surface is clean, flat, and free of paint to achieve optimal frequency response. The top-mounted 2-pin Mil-C-5015 connector simplifies cable routing.

Maintenance & Reliability

Routine inspection of the cable and connector for damage is recommended. The welded hermetic seal and stainless steel housing provide long-term reliability in corrosive environments. Periodic verification of bias voltage (8 to 12 VDC) and sensitivity can confirm sensor health. Following the manufacturer's guidelines ensures maximum service life.
