Bently Nevada 200155-13-05 Low Frequency Trendmaster Pro Accelerometer

Product Overview

When monitoring slow rotating shafts and fin-fan applications, the Bently Nevada 200155-13-05 Low Frequency Trendmaster Pro Accelerometer delivers reliable vibration data. This accelerometer is designed for low frequency measurements and integrates seamlessly with ProTIM option Low Frequency Acceleration-to-Velocity channel types. Built in the USA, it offers robust performance in demanding industrial environments.

Technical Specifications

The 200155-13-05 features a mounted resonant frequency above 20 kHz (>1200 kcpm) and quiescent current below 800 µA. The mounting stud option 13 provides a 3/8-24 to 5/16-18 UNC, 3/4 inch hex stud. Approvals include CSA, ATEX, and IECEx (option 05), ensuring compliance with international safety standards. These parameters make it suitable for continuous vibration monitoring in hazardous areas.

Industry Applications

This accelerometer excels in fin-fan cooling systems and slow rotating machinery, where low frequency vibration analysis is critical. It helps detect early signs of bearing wear, imbalance, or misalignment, reducing unplanned downtime. The robust ceramic shear sensing element and 316L stainless steel housing withstand harsh conditions, making it a reliable choice for petrochemical, power generation, and heavy industrial plants.

Installation & Setup Guidance

Mount the 200155-13-05 using the provided 3/8-24 female thread and tighten to a torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). Ensure the mounting surface is clean and flat for optimal coupling. The accelerometer requires an excitation voltage of 4.7 to 5.5 Vdc and outputs a bias voltage of +2.5 ± 0.23 Vdc. Connect SIG+ and SIG- correctly per polarity markings. Allow 24 hours cure time for adhesive mounting if used.

Maintenance & Reliability

Routine inspection of the accelerometer and its cable connections helps maintain measurement accuracy. The hermetic sealing (5x10⁻⁸ atm·cc/s max) protects against moisture and contaminants. Operating temperature ranges from -40 °C to +105 °C, making it suitable for extreme environments. Periodic verification of sensitivity at 80 Hz (10.2 mV/(m/s²)) ensures consistent performance.

Selection Guide & Purchasing Advice

When selecting the 200155-13-05, verify the mounting stud option and approvals match your site requirements.
