Bently Nevada 200155-17-05 Low Frequency Trendmaster Pro Accelerometer

Product Introduction

In the world of industrial vibration monitoring, the need for precise low frequency measurements has grown as machinery evolves. The Bently Nevada 200155-17-05 Low Frequency Trendmaster Pro Accelerometer addresses this demand directly. Designed for applications like fin-fan cooling systems and slow rotating shafts, this accelerometer delivers reliable performance in challenging environments. As part of the Trendmaster Pro family, it provides accurate data for predictive maintenance strategies, helping reduce unplanned downtime and extend equipment life.

Technical Specifications Breakdown

The 200155-17-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring clear signal output for low frequency vibrations. Its frequency range spans 1.5 to 10,000 Hz (90 to 600,000 cpm), covering the critical spectrum for slow speed machinery. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), minimizing interference from structural resonances. Amplitude linearity is within ±2% from 1 to 10 g peak, providing consistent accuracy. Transverse sensitivity is ≤7%, reducing cross-axis errors. The quiescent current is less than 800 µA, and the output bias voltage is +2.5 ± 0.23 Vdc. Excitation voltage ranges from 4.7 to 5.5 Vdc.

Industry Applications

This accelerometer excels in monitoring fin-fan heat exchangers, where slow rotational speeds demand high sensitivity. It also suits paper machine rolls, cooling tower fans, and other low-speed rotating equipment. By capturing vibration data from these assets, maintenance teams can detect early signs of bearing wear, imbalance, or misalignment. The 200155-17-05 helps shift maintenance from reactive to proactive, reducing costs and improving reliability.

Installation & Setup Guidance

Mount the 200155-17-05 using the 3/8-24 female thread with a mounting 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 mounting surface is clean and flat for optimal coupling. Connect the accelerometer to a compatible ProTIM module with the Low Frequency Acceleration-to-Velocity channel type (-05). Allow up to 2000 ms settling time after power-up for stable readings.

Maintenance & Reliability

The hermetically sealed 316L stainless steel housing protects against harsh environments, with a sealing level of 5X10⁻⁸ atm·cc/s maximum. The ceramic shear sensing element ensures long-term stability. Operating temperature range is -40 °C to +105 °C (-40 °F to +221 °F), with storage capability from -55 °C to +121 °C (-67 °F to +250 °F). Regular inspection of the cable and connector for damage is recommended. The 200155-17-05 withstands axial shock up to 49,050 m/s² pk (5,000 g pk).

Selection Guide & Purchasing Advice

When selecting the 200155-17-05, verify the mounting thread and stud option match your installation. The multiple approvals (CSA, ATEX, and IECEx) make it suitable for hazardous areas.
