Bently Nevada 200155-10-05 Low Frequency Trendmaster Pro Accelerometer Overview

Product Introduction

When monitoring slow rotating shafts and fin-fan applications, the Bently Nevada 200155-10-05 provides reliable low-frequency vibration data. This Low Frequency Trendmaster Pro Accelerometer is part of the Trendmaster Pro family, engineered for precise acceleration measurements in demanding industrial environments. Manufactured in the U.S.A., it offers multiple approvals including CSA, ATEX, and IECEx, ensuring compliance with global safety standards.

Technical Specifications Breakdown

The Bently Nevada 200155-10-05 features a mounted resonant frequency greater than 20 kHz (>1200 kcpm), indicating its ability to capture high-frequency vibrations without resonance interference. Its quiescent current is less than 800 µA, reflecting low power consumption suitable for continuous monitoring. The accelerometer includes a mounting stud option of 10 3/8-24 to 1 NPT with a 1-3/8 inch hex stud, providing flexible installation on various machinery. These specifications highlight its design for low-frequency applications, such as monitoring fin-fan and slow rotating shafts.

Industry Applications

This accelerometer excels in industries where slow-speed machinery requires precise vibration analysis. For example, in petrochemical plants, fin-fan cooling towers operate at low rotational speeds, making the 200155-10-05 ideal for detecting early bearing wear or imbalance. Similarly, in power generation, slow rotating shafts in turbines or pumps benefit from its low-frequency sensitivity. By using this accelerometer, maintenance teams can implement predictive maintenance strategies, reducing unplanned downtime and extending equipment life.

Installation & Setup Guidance

Mount the Bently Nevada 200155-10-05 using the provided 3/8-24 female thread, applying 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 accelerometer connects via a 3/8-24 to 1 NPT stud adapter, allowing integration into existing sensor ports. For best results, position the sensor close to the bearing housing to capture accurate vibration data. Always follow manufacturer guidelines for wiring and configuration to avoid signal degradation.

Maintenance & Reliability

Routine inspection of the accelerometer and its mounting is recommended to maintain measurement accuracy. Check for physical damage or corrosion, especially in harsh environments. The 316L stainless steel housing and hermetic sealing (5x10^-8 atm·cc/s maximum) ensure durability against moisture and contaminants. With a temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF), this sensor withstands extreme conditions. Regular calibration verification helps sustain reliable performance over time.

Selection Guide & Purchasing Advice

Before purchasing the Bently Nevada 200155-10-05, verify compatibility with your monitoring system, particularly the ProTIM option for low-frequency acceleration-to-velocity channel type (-05). Confirm the mounting stud option matches your installation requirements.
