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

Introduction: The Evolution of Vibration Monitoring

In the world of industrial automation, vibration monitoring has evolved from simple periodic checks to continuous, high-precision analysis. The 200350-00-00-00 from Bently Nevada represents this evolution, offering engineers a robust tool for capturing critical machine health data. With a sensitivity of 100 mV/g ±20% and a frequency range spanning 30 to 600,000 cpm, this accelerometer delivers the accuracy needed for predictive maintenance programs.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30 to 600,000 cpm (0.5 to 10,000 Hz)
• 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
• Housing Material: Stainless Steel
• Sealing: Welded Hermetic

A standout feature is the broadband electrical noise of only 350 μg, which ensures clean signals even in electrically noisy environments. This low noise floor is critical for detecting early-stage bearing faults and other subtle vibration patterns.

Real-World Applications

In rotating machinery monitoring, the 200350-00-00-00 excels at capturing vibration data from pumps, motors, fans, and compressors. Its IP68 rating makes it suitable for washdown environments in food processing or chemical plants. Furthermore, the wide operating temperature range allows deployment in both freezing outdoor conditions and high-heat industrial settings. The welded hermetic seal protects the ceramic sensing element from moisture and contaminants, ensuring long-term reliability.

Installation and Setup Guide

Mount the accelerometer using the 1/4-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The 2-pin Mil-C-5015 connector simplifies wiring, and the top electrical connection position facilitates easy cable routing. Allow a settling time of 2.0 seconds after power-up for the output bias voltage to stabilize within 1% of its final value.

Maintenance and Reliability Tips

Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive environments. The stainless steel housing and welded hermetic seal require no routine maintenance, but verify that the mounting torque remains within specification after any system disassembly. Regular calibration checks ensure the sensitivity stays within the ±20% tolerance.

Compatibility and Integration

The 200350-00-00-00 integrates with standard vibration monitoring systems that accept 2 to 20 mA constant current excitation and 8 to 12 VDC bias voltage. Its output impedance of less than 150 ohms allows direct connection to most data acquisition modules.
