200350-02-00-01 Bently Nevada Accelerometer | Case Mounted

Bently Nevada 200350-02-00-01 Technical Profile

The Bently Nevada 200350-02-00-01 is an industrial-grade, case-mounted accelerometer designed for continuous vibration monitoring. It delivers high-accuracy dynamic feedback on high-speed rotating machinery.

This model features a shear-geometry ceramic sensing element that provides a nominal sensitivity of 100 mV/g. It delivers stable performance over a wide frequency spectrum from 0.5 Hz to 10,000 Hz. The electrical circuit is housed in a welded, hermetically sealed stainless steel enclosure carrying an IP68 rating.

The 2-pin MIL-C-5015 top-exit connection provides a robust industrial interface. This model includes a 1/4-28 to M8 stainless steel mounting stud and carries global hazardous area certifications, including CSA, ATEX, and IECEx approvals.

Global PLC Spare HUB's Insight

The Bently Nevada 200350-02-00-01 is a standard choice for balanced, broad-spectrum machinery monitoring. Unlike high-sensitivity low-frequency models, this 100 mV/g sensor balances sensitivity with a wide 50g dynamic range.

The shear crystal geometry isolates the sensor from thermal transients and base strain forces, which often cause false readings in compression-style accelerometers. The physical build is exceptionally compact, and its lightweight 51-gram design prevents mass-loading effects on smaller machinery casings.

With its pre-approved hazardous area certifications, this model is highly versatile for complex processing zones. It provides reliable operation in wet, condensing, or corrosive environments where standard sensors fail.

Configuration Breakdown (Part Number Structural Tree)

The ordering code configuration for the Bently Nevada 200350-02-00-01 accelerometer is structured below:

  • -02 [This Model] — Mounting Stud Option: 1/4-28 UNF to M8 x 1.25 stainless steel adapter stud
  • -00 [This Model] — Sensitivity Tolerance Option: Standard 100 mV/g ± 20% calibration
  • -01 [This Model] — Multi-Agency Approval Option: CSA, ATEX, and IECEx hazardous area certifications
• Physical & Structural Components:
  • Enclosure Shell: Fully welded, hermetically sealed structural stainless steel (IP68 rating)
  • Sensing Element: Piezoelectric ceramic crystal arranged in a shear-mode geometry
  • Connector: Standard top-exit, 2-pin MIL-C-5015 style receptacle

Target Equipment & Plant Applications

• Industrial Gas Turbines: Monitoring high-frequency rotor casing vibration and structural resonance zones.
• High-Speed Centrifugal Compressors: Tracking casing acceleration and blade-pass frequency harmonics.
• Process Water Pumps: Capturing early bearing wear and impellor cavitation profiles.
• Forced Draft Fans: Detecting shaft misalignment and structural looseness on primary air loops.

Diagnostic Capabilities & Signal Integrity

• Broad Frequency Capture: Monitors high-speed machinery states across a wide range of 30 to 600,000 cpm (0.5 to 10,000 Hz).
• High-Impact Resistance: Shock survivability rating of 5,000 g peak protects the sensor during sudden mechanical events.
• Case Isolation Protection: High electrical isolation (greater than 10^8 ohms) prevents ground loop noise from corrupting the dynamic signal.

Global Logistics, Delivery & Warranty Terms

• Express Carriers: Global dispatch via priority DHL, FedEx, and UPS loops.
• Handling Time: Orders are packaged and shipped within 24 to 48 hours of verification.
• Warranty Protection: Includes a full 12-month replacement warranty from Global PLC Spare HUB.

Strategic Procurement & Selection Guide

• Thread Verification: The -02 suffix indicates an M8 x 1.25 metric adapter stud is included. If your machine casing uses a standard imperial 1/4-28 tapped hole, use a standard 1/4-28 double-ended stud instead.
• Cable Grounding Strategy: Use shielded, twisted-pair cabling. To prevent ground loop noise from corrupting your data, ground the shield only at the monitor end, not at the sensor end.
• Torque Limit Warnings: Tighten the sensor to between 2 and 5 ft-lb (2.7 to 6.8 N-m). Under-torquing reduces high-frequency response, while over-torquing can damage the mounting base.

Industrial Frequently Asked Questions (FAQ)

Q: What is the significance of the "Shear" sensing geometry in the 200350 accelerometer?

A: The shear design subjects the ceramic crystal to parallel shear forces rather than compression forces. This design isolates the sensor from base strain and thermal changes, preventing false low-frequency signals.

Q: Why is a settling time of 2.0 seconds required after power-up?

A: The 2.0-second window allows the internal amplifier circuit to charge its coupling capacitor and stabilize its 8 to 12 Vdc bias voltage before outputting valid dynamic signals.

Q: What indicates that the 200350-02-00-01 has suffered internal damage from physical over-range or shock?

A: Check the DC bias voltage at the monitoring system. If the bias voltage drifts outside the specified 8 to 12 Vdc range under static conditions, the internal amplifier or ceramic crystal is likely damaged.

Q: Can this IP68-rated accelerometer be permanently submerged in a water or oil reservoir?

A: No. While the welded stainless steel casing is rated IP68 and handles high humidity and condensing environment, it is designed for non-submerged applications. Permanent submersion will eventually degrade the connector interface.

Q: How does the excitation current level (2 to 20 mA) affect the maximum cable run?

A: Higher excitation currents are needed to drive long cable runs. For runs over 100 feet, increase the excitation current toward the 20 mA limit to overcome cable capacitance and prevent high-frequency signal loss.
