Industry Applications
The 200350-01-00-01 excels in continuous vibration monitoring for critical rotating equipment. In a typical application, it mounts directly on bearing housings of motors and pumps, providing real-time data to condition monitoring systems. Its wide frequency range captures both low-speed and high-speed defects, enabling early detection of imbalance, misalignment, and bearing wear.
Another key use case is in fans and blowers within HVAC or process industries. The accelerometer's IP68 rating allows installation in washdown areas or humid environments without performance degradation. Additionally, the CSA, ATEX, and IECEx approvals make it suitable for explosive atmospheres, such as those found in oil and gas facilities.
Installation & Setup Guidance
Proper mounting is critical for accurate vibration measurement. Use a flat, machined surface of at least 1 inch diameter and ensure it is clean and free of paint or debris. Apply a thin layer of coupling agent (e.g., silicone grease) to improve high-frequency response. Torque the mounting stud to 2–5 ft-lb (2.7–6.8 N-m) using a torque wrench—overtightening can distort the sensor and affect readings.
For the ¼-28 threaded stud, ensure it is fully engaged but not bottomed out. The sensor's top-mounted 2-pin Mil-C-5015 connector should be oriented to avoid cable strain. Use a high-quality, low-noise cable and route it away from power lines to minimize electromagnetic interference. After installation, allow the sensor to settle for at least 2 seconds before taking readings.
Maintenance & Reliability
With no moving parts, the 200350-01-00-01 requires minimal maintenance. However, periodic inspection of the mounting stud and connector is recommended to ensure tightness and corrosion-free contact. In condensing humidity environments, check the sealing integrity annually. The welded hermetic seal and stainless steel housing provide long-term protection, but any physical damage to the cable or connector should be addressed promptly.
Routine calibration checks every 12–24 months are advisable to maintain measurement accuracy. The sensor's broadband electrical noise of 350 μg ensures clean signals even in low-vibration applications, reducing false alarms.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 200350-01-00-01, verify the mounting stud option (¼-28 to M6 x 1.00 stainless steel) and the agency approvals (CSA, ATEX, IECEx) as specified. Ensure your data acquisition system provides 18–28 VDC excitation and 2–20 mA constant current to power the sensor. The output bias voltage of 8–12 VDC should be compatible with your input module.
