The Evolution of Vibration Monitoring in Industry
For decades, industrial plants have relied on vibration analysis to predict equipment failures and reduce unplanned downtime. Early accelerometers offered basic readings, but modern sensors now deliver precise, real-time data that integrates seamlessly with digital monitoring systems. The Bently Nevada 200350-13-00-00 represents this next generation of vibration sensing technology, combining rugged construction with high accuracy for demanding environments.
Introducing the 200350-13-00-00 Accelerometer
Part of the 200350&200355 series, the Bently Nevada 200350-13-00-00 is a ceramic shear accelerometer designed for permanent or temporary vibration monitoring. It features a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%) and a frequency range of 30-600,000 cpm (0.5-10,000 Hz), making it suitable for a wide variety of rotating machinery. The sensor is housed in a stainless steel enclosure with welded hermetic sealing and an IP68 rating, ensuring reliable operation even in condensing humidity or submerged conditions.
Key Technical Specifications and Performance
The 200350-13-00-00 offers a measurement range of ±50 g with amplitude linearity of ±1%, providing accurate readings across its full range. Its mounted resonant frequency is 1500 kcpm (25 kHz), which helps avoid interference from structural resonances. The sensor operates with an excitation voltage of 18 to 28 VDC and constant current excitation of 2 to 20 mA, with an output bias voltage of 8 to 12 VDC. Broadband electrical noise is only 350 μg (3,434 μm/s²) from 1 to 10 kHz, ensuring clean signals for analysis.
Real-World Application in Predictive Maintenance
In a typical chemical processing plant, pumps and compressors run continuously under harsh conditions. The 200350-13-00-00 can be mounted using its magnetic base kit (Mounting Stud option 13) onto a bearing housing, where it monitors vibration levels 24/7. Its wide operating temperature range of -65°F to +250 ºF (-54°C to +121 ºC) and shock survivability of 5,000 g pk make it resilient in extreme environments. Data from the accelerometer feeds into a condition monitoring system, alerting maintenance teams to early signs of bearing wear or imbalance before catastrophic failure occurs.
Integration and Compatibility Considerations
The accelerometer uses a 2-Pin Mil-C-5015 electrical connector with top exit, simplifying wiring in tight spaces. Its output impedance is less than 150 ohms, and the discharge time constant is ≥0.3 seconds, ensuring compatibility with most industrial data acquisition systems. The sensor requires a constant current excitation source between 2 and 20 mA, which is standard on many vibration monitoring modules.
