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

Product Introduction

When monitoring slow rotating shafts or fin-fan applications, standard accelerometers often fail to capture critical low-frequency vibrations. The Bently Nevada 200155-05-CN Low Frequency Trendmaster Pro Accelerometer addresses this challenge directly. Designed as part of the Trendmaster Pro family, this accelerometer delivers reliable performance in demanding industrial environments. Manufactured in the U.S.A., the 200155-05-CN is built for continuous condition monitoring where low-frequency accuracy is essential.

Technical Specifications

The Bently Nevada 200155-05-CN features a mounted resonant frequency greater than 20 kHz (>1200 kcpm), ensuring minimal interference from structural resonances. Its quiescent current is less than 800 µA, contributing to low power consumption in long-term monitoring setups. The product type is clearly defined as Low Frequency Trendmaster Pro Accelerometer, with approvals designated as CN for country-specific requirements. These specifications make the 200155-05-CN suitable for precise vibration measurement in challenging environments.

Industry Applications

The 200155-05-CN excels in two primary applications: fin-fan cooling systems and slow rotating shafts. In fin-fan applications, low-frequency vibrations from blade pass and structural resonances require an accelerometer with extended low-frequency response. For slow rotating shafts, typical in large fans or pumps, the 200155-05-CN captures critical vibration data that standard accelerometers miss. This capability helps maintenance teams detect early signs of bearing wear or imbalance, reducing unplanned downtime.

Installation & Setup Guidance

Proper mounting is crucial for accurate readings. The 200155-05-CN uses a 3/8-24 female mounting thread. The -05 option includes a 3/8-24 to 1/4-28 UNF 1-3/8 inch hex plate stud for versatile installation. Mounting torque should be applied carefully to avoid over-tightening. When used with the ProTIM option, ensure the channel type is set to Low Frequency Acceleration-to-Velocity for optimal performance. Always verify the excitation voltage range (4.7 to 5.5 Vdc) matches your system's power supply.

Maintenance & Reliability

The 200155-05-CN is built with a 316L stainless steel housing and connector, providing excellent corrosion resistance in harsh environments. Its hermetic sealing (5X10-8 atm•cc/s maximum) protects internal components from moisture and contaminants. The ceramic shear sensing element offers long-term stability. Regular inspection of the mounting stud and cable connections is recommended to maintain measurement integrity. The accelerometer operates reliably across a wide temperature range, from -40 ºC to +105 ºC.

Buying Guide

Before purchasing the Bently Nevada 200155-05-CN, verify your system's compatibility with the Trendmaster Pro platform. Confirm the mounting thread requirement (3/8-24 female) and whether the -05 stud option is needed. For complete technical specifications and current availability, contact BluePLC Industrial.
