Bently Nevada 200155-20-05 Low Frequency Trendmaster Pro Accelerometer

Product Introduction

In the world of industrial automation, monitoring slow rotating shafts and fin-fan applications has always presented unique challenges. The Bently Nevada 200155-20-05 Low Frequency Trendmaster Pro Accelerometer addresses these needs with precision and reliability. As part of the Trendmaster Pro family, this accelerometer is engineered to deliver accurate vibration data in demanding environments, helping maintenance teams detect early signs of mechanical wear and prevent unplanned downtime.

Technical Specifications Breakdown

The 200155-20-05 offers a mounting stud option of 3/8-24 thread with one magnetic mount base, simplifying installation on ferrous surfaces. It carries multiple approvals including CSA, ATEX, and IECEx, ensuring compliance with global safety standards. The accelerometer features a mounted resonant frequency greater than 20 kHz (>1200 kcpm) and a quiescent current of less than 800 µA, making it suitable for continuous monitoring in hazardous areas.

Industry Applications

This accelerometer excels in monitoring slow rotating shafts in industries such as petrochemical, power generation, and mining. For example, in fin-fan cooling systems, the 200155-20-05 detects low-frequency vibrations that could indicate bearing degradation or imbalance. By integrating this sensor into a predictive maintenance program, operators can schedule repairs during planned outages rather than reacting to sudden failures.

Installation & Setup Guidance

Mounting the 200155-20-05 is straightforward thanks to the magnetic base option. Ensure the mounting surface is clean and flat for optimal magnetic adhesion. Torque the 3/8-24 stud to 2.7 to 6.8 N·m (2 to 5 ft·lbf) as specified. Connect the accelerometer to a compatible ProTIM module configured for low frequency acceleration-to-velocity channel type (-05). Verify the output bias voltage and quiescent current after installation to confirm proper operation.

Maintenance & Reliability

Routine inspection of the accelerometer and its mounting is recommended to ensure consistent performance. Check the magnetic base for debris or damage, and verify that the cable connections remain secure. The hermetically sealed 316L stainless steel housing protects against harsh environments, while the ceramic shear sensing element provides long-term stability.
