Applications and Use Cases

The 200155-17-05 excels in low-frequency vibration monitoring for fin-fan and slow rotating shafts. It is ideal for applications where precise acceleration measurement is critical, such as in cooling towers or large rotating equipment. Its rugged design ensures reliable operation in harsh industrial environments.

Installation and Setup

Mount the accelerometer using the 3/8-24 female thread with a torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The mounting stud option is 17 3/8-24 to 3/8-16 UNC 1-3/8 inch hex plate stud. Ensure the base is clean and flat for optimal coupling. After installation, allow 24 hours cure time before full operation.

Maintenance and Reliability

Regular inspection of the 200155-17-05 helps maintain accuracy. Check for physical damage or contamination. The hermetically sealed design protects against moisture and dust. Follow manufacturer guidelines for periodic verification of sensitivity and bias voltage.

Compatibility and Integration

This accelerometer works with ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). It is part of the Bently Nevada Trendmaster Pro family, ensuring seamless integration with existing monitoring systems. The multiple approvals (CSA, ATEX, and IECEx) expand its global applicability.

Troubleshooting and Common Issues

If output bias voltage deviates from +2.5 ± 0.23 Vdc, check excitation voltage (4.7 to 5.5 Vdc) and quiescent current (2000 ms) may indicate improper mounting or environmental stress. Verify cable connections and sensor grounding.
