Product Overview
When unplanned downtime strikes rotating machinery, the Bently Nevada 200350-01-00-01 200350 Accelerometers deliver precise vibration data to protect your assets. This ceramic shear accelerometer provides a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, making it suitable for critical applications in oil and gas, power generation, and heavy manufacturing. With a frequency response of 30-600,000 cpm (0.5-10,000 Hz), it captures both low-speed and high-frequency vibrations.
Technical Specifications Breakdown
The 200350-01-00-01 offers key parameters that directly impact maintenance costs and operational efficiency:
- Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%) ensures consistent output for accurate trend analysis, reducing false alarms and unnecessary inspections.
- Frequency Range: 30-600,000 cpm (±3 dB) covers a broad spectrum, enabling early detection of bearing wear and imbalance without extra sensors.
- Measurement Range: ±50g handles moderate to high vibration levels, avoiding saturation in demanding environments.
- Output Bias Voltage: 8 to 12 VDC provides a stable baseline, simplifying integration with monitoring systems and minimizing setup time.
- Excitation Voltage: 18 to 28 VDC with constant current 2 to 20 mA ensures compatibility with standard industrial power supplies, reducing retrofit costs.
These specs translate to lower total cost of ownership by extending equipment life and reducing unplanned repairs.
Industry Applications
Oil and Gas Refineries
In refinery compressor trains, the 200350-01-00-01’s IP68 enclosure rating and welded hermetic sealing withstand corrosive atmospheres and washdowns. Its 100% relative humidity tolerance (condensing, non-submerged) eliminates moisture-related failures, cutting replacement expenses by up to 30%.
Power Generation Turbines
For steam and gas turbines, the accelerometer’s shock survivability of 5,000 g pk and transverse sensitivity ≤7% ensure reliable data during startup transients. This reduces false trip events and associated production losses.
Installation & Setup Guidance
Mount the 200350-01-00-01 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 01 (¼-28 to M6 x 1.00 stainless steel) simplifies retrofitting. Connect via the 2-pin Mil-C-5015 connector at the top position. Allow 2.0 seconds settling time (within 1% of bias) before taking critical measurements. Proper torque avoids signal distortion and extends sensor life.
Maintenance & Reliability
Routine inspection of the electrical connector and cable integrity prevents intermittent faults. The ceramic sensing element and stainless steel housing resist wear, while the welded hermetic seal protects against contaminants. With a discharge time constant ≥0.3 sec, the accelerometer maintains accuracy over long monitoring intervals, reducing calibration frequency and associated labor costs.
Selection Guide & Purchasing Advice
Before ordering, verify your system’s excitation voltage (18 to 28 VDC) and constant current (2 to 20 mA) compatibility. The agency approvals option 01 includes CSA, ATEX, and IECEx certifications for hazardous areas. SpareTechPLC stocks this exact model with fast shipping and expert support to minimize your procurement risk.
