200350-10-00-00 | Bently Nevada 100 mV/g Accelerometer

Introduction to the 200350-10-00-00

When machinery vibration threatens uptime, the 200350-10-00-00 from Bently Nevada provides precise measurement. This 200350 series accelerometer offers 100 mV/g sensitivity with ±20% tolerance, making it suitable for a wide range of industrial monitoring tasks. Manufactured in the USA, it combines rugged stainless steel construction with a ceramic shear sensing element for consistent performance.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30-600,000 cpm (0.5-10,000 Hz) ±3 dB
• Measurement Range: ±50 g
• Output Bias Voltage: 8 to 12 VDC
• Excitation Voltage: 18 to 28 VDC
• Constant Current Excitation: 2 to 20 mA
• Operating Temperature: -65°F to +250°F (-54°C to +121°C)
• Enclosure Rating: IP68
• Weight: 0.051 kg

One distinctive spec is the broadband electrical noise of only 350 μg (3,434 μm/s²) from 1-10 kHz. This low noise floor ensures accurate vibration readings even in electrically noisy environments, reducing false alarms and improving diagnostic reliability.

Real-World Applications

With its 100% relative humidity tolerance and IP68 rating, the 200350-10-00-00 excels in wet, condensing conditions where other sensors fail. Typical use cases include pump monitoring, compressor vibration analysis, and fan bearing health checks. The wide frequency range (0.5-10,000 Hz) covers both low-speed and high-speed rotating equipment, making it a versatile choice for predictive maintenance programs.

Installation and Setup

Mounting is straightforward using the 1/4-28 female thread and adhesive stud mount (option 10). Apply a maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to secure the sensor. The top-mounted 2-pin Mil-C-5015 connector simplifies wiring, while the welded hermetic seal protects internal components from moisture and contaminants. Allow 2.0 seconds settling time (within 1% of bias) after power-up before taking measurements.

Maintenance and Reliability

Routine inspection of the cable and connector ensures long-term reliability. The stainless steel housing resists corrosion, and the ceramic sensing element provides stable performance over time. Because the 200350-10-00-00 is sealed and non-serviceable, periodic verification of output bias voltage (8-12 VDC) confirms proper operation. Following the manufacturer's guidelines for shock survivability (5,000 g pk) helps avoid damage from accidental impacts.

Compatibility and Integration

This accelerometer works with standard Bently Nevada monitoring systems and any data acquisition equipment that supplies 18-28 VDC excitation and accepts a 100 mV/g analog input. The low output impedance (<150 ohms) allows long cable runs without signal degradation. For best results, use a constant current source between 2 and 20 mA.

Troubleshooting and Common Issues

If output bias voltage drifts outside 8-12 VDC, check the excitation supply and cable continuity. High noise levels may indicate grounding issues or electromagnetic interference. Verify that the mounting torque is within 2-5 ft-lb to avoid resonance shifts. For persistent problems, consult the Bently Nevada documentation or contact Petro Auto Tech for support.
