Introduction
When unexpected machinery vibrations threaten production uptime, the Bently Nevada 200350-02-00-01 200350 Accelerometers deliver precise, reliable data to keep your operations running smoothly. This high-performance accelerometer is engineered for demanding industrial applications where accurate vibration measurement is critical.
Technical Specifications Breakdown
The 200350-02-00-01 offers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), ensuring consistent output for vibration analysis. Its measurement range of ±50g covers a wide spectrum of machinery conditions, from normal operation to severe faults. The frequency range spans 30 to 600,000 cpm (0.5 to 10,000 Hz), making it suitable for both low-speed and high-speed rotating equipment.
Key performance specs include:
- Amplitude Linearity: ±1% for accurate signal representation
- Mounted Resonant Frequency: 1500 kcpm (25 kHz) for high-frequency response
- Broadband Electrical Noise (1-10 kHz): 350 μg (3,434 μm/s²) for clean data
- Output Bias Voltage: 8 to 12 VDC
- Excitation Voltage: 18 to 28 VDC with constant current 2 to 20 mA
- Settling Time: 2.0 seconds within 1% of bias
- Output Impedance: <150 ohms
- Discharge Time Constant: ≥0.3 seconds
- Electrical Isolation (Case): >108 ohms
These parameters ensure the sensor delivers stable, low-noise signals for condition monitoring systems.
Industry Applications
In petrochemical plants, the 200350-02-00-01 monitors pumps and compressors for early signs of bearing wear or imbalance. Its IP68 enclosure rating withstands washdown environments and high humidity (100% relative, condensing, non-submerged). For power generation, the sensor’s wide frequency range captures both low-speed turbine vibrations and high-frequency gear mesh signals. The stainless steel housing and welded hermetic sealing provide durability in corrosive atmospheres.
Installation & Setup Guidance
Mount the accelerometer using the 1/4-28 female thread with a maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option (02) is ¼-28 to M8 x 1.25 stainless steel. Ensure the mounting surface is clean and flat for optimal coupling. Connect via the 2-pin Mil-C-5015 top-mounted electrical connector. Apply excitation voltage between 18 and 28 VDC with constant current 2 to 20 mA. Allow 2.0 seconds settling time after power-up before taking measurements.
Maintenance & Reliability
The ceramic shear sensing element and welded hermetic seal minimize drift and contamination. The sensor survives shock up to 5,000 g pk, reducing risk from accidental impacts. Regular inspection of the connector and cable integrity helps maintain signal quality. The IP68 rating allows continuous operation in wet conditions, extending service life in harsh environments.
Compatibility & Integration
This accelerometer integrates with most vibration monitoring systems that accept IEPE/constant current inputs. The 100 mV/g sensitivity is standard for industrial data collectors and online monitoring systems. The CSA, ATEX, and IECEx agency approvals (option 01) ensure compliance for hazardous area installations.
Selection Guide & Purchasing Advice
Before ordering, verify the mounting thread and connector type match your application. The 200350-02-00-01 includes the ¼-28 to M8 x 1.25 stud and CSA/ATEX/IECEx approvals.
