Industry Applications
This accelerometer is engineered for low-frequency vibration monitoring on fin-fan cooling systems and slow rotating shafts. These assets often operate at speeds below 600 RPM, generating vibrations in the 1.5 to 10,000 Hz range, which the 200155-15-05 captures with high fidelity. The Bently Nevada 200155-15-05 excels in:
- Cooling tower fin-fan monitoring
- Paper machine rolls and dryer sections
- Centrifugal pumps and compressors with slow-speed shafts
- Generators and turbines in low-speed auxiliary drives
By providing accurate data on machinery health, this module supports predictive maintenance strategies, reducing unplanned downtime.
Installation & Setup
Proper mounting is essential for accurate readings. Follow these guidelines for the Bently Nevada 200155-15-05:
-
Surface Preparation: Ensure the mounting surface is flat, clean, and free of paint or debris.
-
Mounting Torque: Tighten the stud to 2.7 to 6.8 N•m (2 to 5 ft•lbf) to achieve a solid mechanical connection.
-
Stud Orientation: The mounting stud option (3/8-24 to 3/8-16 UNC, 3/4 inch hex) provides flexibility for various bracket configurations.
-
Cable Routing: Route cables away from high-temperature surfaces and moving parts to prevent damage.
-
Excitation Voltage: Ensure the power supply provides 4.7 to 5.5 Vdc to the accelerometer.
Maintenance & Reliability
The 200155-15-05 is built to withstand harsh industrial environments. Its 316L stainless steel housing and hermetic sealing protect against moisture and contaminants. However, routine checks are recommended:
- Inspect the mounting stud for loosening due to vibration.
- Check cable integrity for cuts or abrasion.
- Verify the output bias voltage remains within +2.5 ± 0.23 Vdc.
With proper care, this accelerometer delivers long-term reliability, minimizing lifecycle costs.
Selection Guide
When selecting a replacement or new accelerometer, verify the model number 200155-15-05 matches your system requirements. This module is specifically designed for use with the ProTIM option for Low Frequency Acceleration-to-Velocity channel type (-05). Confirm compatibility with your existing monitoring hardware.
