Bently Nevada 200155-16-05 Low Frequency Trendmaster Pro Accelerometer

Product Introduction

When monitoring slow rotating shafts in industrial environments, the Bently Nevada 200155-16-05 Low Frequency Trendmaster Pro accelerometer provides reliable vibration data. This sensor is part of the Trendmaster Pro family and is specifically designed for applications such as fin-fan cooling towers and other low-speed machinery. It features a ceramic shear sensing element and a 316L stainless steel housing for durability in harsh conditions.

Technical Specifications Breakdown

The 200155-16-05 offers a mounted resonant frequency greater than 20 kHz (>1200 kcpm), ensuring accurate measurements across its operating range. Its quiescent current is less than 800 µA, indicating low power consumption. The mounting stud option 16 provides a 3/8-24 to 1/2-13 UNC thread with a 3/4 inch hex stud for secure installation. The approval code 05 signifies multiple certifications including CSA, ATEX, and IECEx, making it suitable for hazardous locations.

Industry Applications

This accelerometer excels in monitoring fin-fan assemblies and slow rotating shafts where low-frequency vibration is critical. For example, in petrochemical plants, the 200155-16-05 helps detect early signs of bearing wear or imbalance in large cooling fans. Its low frequency response down to 1.5 Hz (90 cpm) captures subtle vibrations that higher frequency sensors might miss, enabling predictive maintenance and reducing unplanned downtime.

Installation & Setup Guidance

Mount the 200155-16-05 using the provided 3/8-24 female thread and apply a mounting torque between 2.7 to 6.8 N·m (2 to 5 ft·lbf). Ensure the mounting surface is clean and flat for optimal coupling. The sensor uses a 3/4 inch hex stud for easy tightening. After installation, allow a cure time of 24 hours before taking critical measurements to ensure the sensor settles properly.

Maintenance & Reliability

Routine inspection of the mounting integrity and cable connections helps maintain reliable performance. The hermetically sealed design with a maximum leak rate of 5x10⁻⁸ atm·cc/s protects against moisture and contaminants. The 316L stainless steel construction resists corrosion in humid or chemically aggressive environments. Periodic verification of the output bias voltage and sensitivity ensures the sensor remains within specification.

Selection Guide & Purchasing Advice

Before purchasing the Bently Nevada 200155-16-05, verify compatibility with your monitoring system and confirm the mounting thread requirements. This model is ideal for low-frequency applications like fin-fan and slow rotating shafts. For complete technical specifications and current availability, contact BluePLC Industrial.
