These specifications ensure the accelerometer performs reliably in harsh conditions, providing accurate data for predictive maintenance.
Industry Applications
The 200150-15-05 excels in general application environments where vibration monitoring is critical. Common use cases include:
- Rotating Machinery Monitoring: Track bearing health and imbalance in pumps, motors, fans, and compressors. The 10.2 mV/(m/s²) sensitivity captures subtle vibration changes.
- Process Industry Equipment: Monitor agitators, blowers, and centrifuges in chemical or petrochemical plants. The hermetic sealing and 316L stainless steel housing resist corrosive atmospheres.
- Power Generation Assets: Detect early signs of wear in turbines and generators. The wide frequency range (10 to 1000 Hz) covers both low-speed and high-speed machinery.
Compared to standard accelerometers, the 200150-15-05 offers higher sensitivity and broader frequency response, making it suitable for both low-level and high-amplitude vibration monitoring.
Installation & Setup Guidance
Proper mounting is essential for accurate readings. The accelerometer features a 3/8-24 female mounting thread. Use the included stud option (15 = 3/8-24 to 3/8-16 UNC, 3/4 inch hex stud) for secure attachment. Apply a mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) to ensure consistent coupling.
For best results, mount the accelerometer on a clean, flat surface directly on the machine housing. Avoid mounting on painted or uneven surfaces. The settling time of ≤300 ms allows quick stabilization after power-up.
Maintenance & Reliability
The 200150-15-05 requires minimal maintenance due to its robust construction. The ceramic shear sensing element and 316L stainless steel housing provide long-term durability. Operate within the temperature range of -40 ºC to +105 ºC to maintain accuracy. The hermetic seal prevents moisture ingress, even in 100% condensing humidity.
Regularly inspect the mounting integrity and cable connections. The accelerometer's design ensures stable performance over time, reducing the need for frequent recalibration.
Compatibility & Integration
This accelerometer works with Bently Nevada Trendmaster systems, specifically the ProTIM option with Standard Acceleration-to-Velocity channel type (-01). It integrates seamlessly into existing vibration monitoring networks. The multiple approvals (CSA, ATEX, and IECEx) allow use in hazardous locations.
Buying Guide
