Bently Nevada 200155-15-05 Low Frequency Trendmaster Pro Accelerometer

Product Introduction

When monitoring slow rotating shafts in industrial environments, the Bently Nevada 200155-15-05 Low Frequency Trendmaster Pro Accelerometer delivers reliable vibration data. This sensor is designed for applications like fin-fan cooling towers and other low-speed machinery where precise acceleration measurements are critical. With multiple approvals including CSA, ATEX, and IECEx, it meets stringent safety standards for hazardous locations.

Technical Specifications Breakdown

The 200155-15-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring accurate readings for low-frequency vibrations. Its measurement range spans ±196 m/s² (±20 g), suitable for typical industrial vibration levels. The frequency range extends from 1.5 to 10,000 Hz (90 to 600,000 cpm), covering both low and moderate speed machinery. A mounted resonant frequency above 20 kHz (>1200 kcpm) prevents interference from structural resonances. The quiescent current is less than 800 µA, contributing to low power consumption and reduced operational costs over time.

Industry Applications

This accelerometer excels in fin-fan applications where slow rotating shafts require precise vibration monitoring. By detecting early signs of bearing wear or imbalance, it helps avoid unplanned downtime and costly repairs. In chemical plants and refineries, its hermetically sealed 316L stainless steel housing withstands harsh environments, extending service life and lowering total cost of ownership. The multiple approvals (CSA, ATEX, IECEx) simplify compliance across global facilities, reducing certification overhead.

Installation & Setup Guidance

Mount the 200155-15-05 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 stud option 15 provides a 3/8-24 to 3/8-16 UNC adapter for versatile installation. Ensure the mounting surface is clean and flat to achieve optimal frequency response. Allow 24 hours cure time for any adhesive used. Proper installation minimizes signal noise and maximizes measurement accuracy, directly impacting maintenance efficiency and cost savings.

Maintenance & Reliability

Routine inspection of the accelerometer and its cabling helps maintain reliable performance. The ceramic shear sensing element offers long-term stability, reducing recalibration frequency. With an axial shock limit of 49,050 m/s² pk (5,000 g pk), the device withstands accidental impacts without damage. Operating temperature range from -40 °C to +105 °C (-40 °F to +221 °F) ensures functionality in extreme conditions. These features collectively lower maintenance expenses and extend replacement intervals, supporting a favorable return on investment.

Selection Guide & Purchasing Advice

When selecting the 200155-15-05, verify compatibility with your monitoring system and mounting requirements. This model includes multiple approvals (CSA, ATEX, IECEx) for hazardous area use.
