Solving Vibration Monitoring Challenges in Harsh Industrial Environments
When engineers face the challenge of monitoring vibration in environments with extreme moisture, temperature swings, and physical shock, they need a sensor that can withstand these conditions without sacrificing accuracy. The Bently Nevada 200350-11-00-00 accelerometer is designed precisely for such scenarios, offering robust performance in applications ranging from rotating machinery to structural health monitoring.
This model is part of the 200350&200355 series, manufactured in the U.S.A., and is available through SpareTechPLC. Its IP68 enclosure rating ensures reliable operation even in condensing humidity or temporary submersion, making it a trusted choice for critical asset protection.
Key Technical Specifications and Performance
The 200350-11-00-00 delivers a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%), providing clear vibration signals for analysis. Its frequency range spans 30 to 600,000 cpm (0.5 to 10,000 Hz), covering a broad spectrum of machine faults from imbalance to high-frequency bearing defects.
With a measurement range of ±50 g and transverse sensitivity of ≤7%, this accelerometer maintains accuracy even under high-amplitude vibrations. The mounted resonant frequency of 1500 kcpm (25 kHz) ensures reliable data capture well beyond typical machine speeds.
Electrical performance is equally robust: output bias voltage is 8 to 12 VDC, excitation voltage is 18 to 28 VDC, and constant current excitation ranges from 2 to 20 mA. The settling time within 1% of bias is 2.0 seconds, and output impedance is less than 150 ohms. The discharge time constant is ≥0.3 seconds, and electrical isolation from the case exceeds 108 ohms.
Real-World Application Example
In a typical chemical processing plant, pumps and compressors operate in areas with high humidity and occasional washdowns. The 200350-11-00-00, with its IP68 rating and welded hermetic sealing, can be mounted directly on these machines using the M6x1 adhesive stud mount. Its stainless steel housing and ceramic shear sensing element provide long-term stability, while the 2-pin Mil-C-5015 connector ensures a secure electrical connection.
This setup allows maintenance teams to continuously monitor vibration levels, detect early signs of bearing wear or imbalance, and schedule repairs before unplanned downtime occurs. The accelerometer's shock survivability of 5,000 g pk adds an extra layer of durability in case of sudden impacts.
