Introduction
In the evolving landscape of industrial automation, the need for precise and durable vibration monitoring has never been greater. The Bently Nevada 200350-09-00-00 200350 Accelerometers stand as a testament to engineering excellence, designed to meet the rigorous demands of modern machinery health monitoring. As part of the trusted 200350 series, this accelerometer delivers reliable performance in harsh environments, ensuring your operations run smoothly with minimal downtime.
Technical Specifications Breakdown
The Bently Nevada 200350-09-00-00 200350 Accelerometers come equipped with a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), providing accurate vibration measurements across a frequency range of 30-600,000 cpm (0.5-10,000 Hz) at ±3 dB. With a measurement range of ±50g and transverse sensitivity ≤7%, this sensor captures both subtle and extreme vibrations. The amplitude linearity of ±1% ensures consistent output, while the mounted resonant frequency of 1500 kcpm (25 kHz) supports high-frequency applications. Broadband electrical noise is kept low at 350 μg (3,434 μm/s²) over 1-10 kHz, and the output bias voltage ranges from 8 to 12 VDC. Excitation voltage requirements are 18 to 28 VDC with constant current excitation of 2 to 20 mA, and the settling time within 1% of bias is 2.0 seconds. Output impedance is less than 150 ohms, and the discharge time constant is ≥0.3 seconds, with electrical isolation (case) exceeding 108 ohms. The operating temperature range spans -65°F to +250 ºF (-54°C to +121 ºC), and the device withstands shock survivability of 5,000 g pk. It operates in 100% relative humidity (condensing, non-submerged) and carries an IP68 enclosure rating.
Industry Applications
In industries such as oil and gas, power generation, and manufacturing, the 200350-09-00-00 excels at monitoring rotating machinery like pumps, compressors, and turbines. Its wide frequency range and high sensitivity make it ideal for early fault detection, preventing costly unplanned outages. For example, in a petrochemical plant, this accelerometer can detect bearing wear in centrifugal pumps, allowing maintenance teams to schedule repairs during planned shutdowns. The IP68 rating ensures reliable operation in wet or dusty environments, such as offshore platforms or mining operations.
Installation & Setup Guidance
Proper installation is critical for accurate readings. The 200350-09-00-00 features a 1/4-28 female mounting thread and requires a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Ensure the mounting surface is clean and flat to achieve optimal coupling. The device uses a 2-Pin Mil-C-5015 electrical connector positioned at the top, simplifying wiring. No mounting stud is included (option 09), so plan accordingly. Always verify the excitation voltage (18 to 28 VDC) and constant current (2 to 20 mA) before powering the sensor.
Maintenance & Reliability
To maximize the lifespan of your Bently Nevada 200350-09-00-00 200350 Accelerometers, perform regular inspections of the cable and connector for damage. The welded hermetic sealing and stainless steel housing provide excellent protection against moisture and corrosion, but periodic checks ensure long-term reliability. Given the IP68 rating, the sensor can withstand immersion, but avoid prolonged exposure to corrosive chemicals. Routine calibration verification every 12 months helps maintain accuracy.
Compatibility & Integration
This accelerometer integrates seamlessly with Bently Nevada monitoring systems and most industrial data acquisition platforms that accept standard IEPE (Integrated Electronics Piezo-Electric) inputs. The 2-pin Mil-C-5015 connector is a common interface, simplifying replacement in existing setups. Ensure your system supports the 8 to 12 VDC output bias and can supply the required 18 to 28 VDC excitation voltage with 2 to 20 mA constant current.
Selection Guide & Purchasing Advice
When ordering the 200350-09-00-00, confirm the mounting thread (1/4-28 female) and connector type match your application. This variant includes no mounting stud and no agency approvals, making it suitable for general industrial use. For specialized environments requiring certifications, consult SpareTechPLC for alternative options.
