Bently Nevada 200355-00-00-00 Accelerometer: Precision Vibration Monitoring for Critical Machinery

Core Technical Specifications and Performance Characteristics

• The Bently Nevada 200355-00-00-00 provides a standard sensitivity of 100 mV/g (±20%) for reliable vibration measurement. It covers a frequency range of 30 to 600,000 CPM (0.5 to 10,000 Hz). This wide bandwidth suits most industrial rotating machinery applications. The sensor handles dynamic ranges up to ±50 g peak. Its transverse sensitivity stays below 7% for accurate readings.
• This model operates reliably across an extreme temperature range of -54°C to +121°C. It withstands 100% condensing humidity and carries an IP68 environmental rating. The unit survives mechanical shock up to 5,000 g peak. It maintains low broadband noise of 350 µg across the 1 to 10 kHz range. The ceramic shear element ensures excellent long-term stability.
• The device requires excitation voltage of 18 to 28 VDC with 2 to 20 mA constant current. It delivers an output bias voltage between 8 and 12 VDC. Output impedance measures below 150 ohms for signal integrity. The discharge time constant meets or exceeds 0.3 seconds. Mounted resonant frequency reaches 1,500 kCPM (25 kHz).

Frequently Asked Questions (FAQ)

• What is the difference between the 200355 and 200350 models?
  The Bently Nevada 200355 features a top-mounted 2-pin connector configuration. The 200350 typically offers a different connector orientation or mounting option. Both models share the same ceramic shear sensing element and performance specifications. You should select based on your installation space and cabling requirements. Consult the datasheet for dimensional differences between models.
• Can I use this sensor in hazardous area applications?
  The standard Bently Nevada 200355-00-00-00 does not include intrinsic safety approvals. Models with approval suffixes may offer certifications for hazardous locations. Check the specific approvals suffix in your model number. You may need to select a variant with appropriate safety certifications. Always verify area classification requirements before installation.
• How do I interpret the model number suffix codes?
  The full model number 200355-00-00-00 breaks down into specific configuration options. The first suffix (red) indicates the mounting stud type: 00 is 1/4-28 stainless with brass tip. The second suffix (blue) represents tolerance: 00 means 100 mV/g ±20% sensitivity. The third suffix (green) designates approvals: 00 means no agency approvals. You can customize these suffixes for your specific needs.
• What cable should I use with this accelerometer?
  You need a mating 2-pin Mil-C-5015 style cable connector for the 200355. Bently Nevada offers compatible cables with various lengths and jacketing materials. Select cables with appropriate temperature ratings for your environment. Use shielded twisted pair cable for best signal integrity. Ensure the cable assembly maintains the IP68 rating when connected.
• How does the ceramic shear element improve performance?
  The ceramic shear design in the Bently Nevada 200355 minimizes base strain and thermal transient effects. It provides excellent rejection of transverse motion and mounting torque variations. This technology ensures accurate measurements over the sensor's entire operational life. Ceramic elements offer superior stability compared to some piezoelectric materials. The design contributes to the wide frequency response characteristics.
