200355-00-00-00 | Bently Nevada 100 mV/g Accelerometer

Introduction to the Bently Nevada 200355-00-00-00 Accelerometer

When reliable vibration monitoring is critical for rotating machinery, the 200355-00-00-00 from Bently Nevada provides accurate data in demanding conditions. This 200350 series accelerometer offers a sensitivity of 100 mV/g ±20%, making it suitable for a wide range of industrial applications. Manufactured in the U.S.A., it is designed for continuous operation in harsh environments.

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)
• 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 specification is the IP68 enclosure rating, which allows the 200355-00-00-00 to withstand continuous submersion in water, ensuring reliable performance in wet or condensing environments.

Applications and Use Cases

This accelerometer is ideal for vibration monitoring on pumps, fans, compressors, and other rotating equipment. Its rugged stainless steel construction and welded hermetic sealing make it suitable for offshore, chemical, and food processing plants where moisture and contaminants are present. The 100% relative humidity rating ensures operation even in condensing conditions without submersion.

Installation and Setup

The 200355-00-00-00 features a 1/4-28 female mounting thread and a ¼-28 stainless steel mounting stud with brass tip. Recommended mounting torque is 2 to 5 ft-lb (2.7 to 6.8 N-m). The top-mounted 2-pin Mil-C-5015 electrical connector simplifies wiring. Ensure the mounting surface is clean and flat for optimal coupling.

Maintenance and Reliability

With a welded hermetic seal and stainless steel housing, the 200355-00-00-00 requires minimal maintenance. Periodic inspection of the cable and connector for damage is recommended. The ceramic shear sensing element provides long-term stability and accuracy, reducing the need for frequent recalibration.

Compatibility and Integration

This accelerometer is compatible with Bently Nevada monitoring systems and other data acquisition equipment that accepts IEPE-type sensors with constant current excitation of 2 to 20 mA. The output bias voltage of 8 to 12 VDC ensures compatibility with most industrial vibration monitoring systems.
