Bently Nevada 200150-21-05 General Purpose Accelerometer for Trendmaster Systems

Solving Vibration Monitoring Challenges with the Bently Nevada 200150-21-05

When critical rotating machinery begins to show subtle changes in vibration, engineers need a reliable sensor to capture those early warning signs. The Bently Nevada 200150-21-05 general purpose accelerometer provides the precise data required for effective condition monitoring. Designed for use with Trendmaster 2000 or Trendmaster Pro systems, this accelerometer helps maintenance teams detect developing faults before they lead to unplanned downtime.

Product Overview

The Bently Nevada 200150-21-05 is a general purpose accelerometer manufactured in the U.S.A. It is part of the Trendmaster family and is suitable for a wide range of industrial applications. The unit features a mounting stud option 21, which includes a 3/8-24 outer diameter to M6x1 inner diameter with a 1-3/8 inch hex plate stud. This accelerometer comes with multiple approvals: CSA, ATEX, and IECEx, making it suitable for use in hazardous environments.

Technical Specifications

Key specifications for the 200150-21-05 include:

Mounted resonant frequency: >20 kHz (>1200 kcpm)

Quiescent current: <800 µA

Mounting stud option: 21 = 3/8-24 outer diameter to M6x1 inner diameter, 1-3/8 inch hex plate stud

Approvals: Multiple (CSA, ATEX, and IECEx)

These parameters ensure the accelerometer delivers accurate vibration readings across a broad frequency range while maintaining low power consumption.

Industry Applications

This accelerometer excels in general purpose vibration monitoring applications. Typical use cases include:

Monitoring pumps, fans, and compressors in process industries

Condition monitoring of motors and generators in power generation

Vibration analysis on rotating equipment in oil and gas facilities

With its multiple approvals, the 200150-21-05 is well-suited for both safe area and hazardous location installations, reducing the need for different sensor types across a plant.

Installation & Setup Guidance

Proper mounting is critical for accurate vibration measurement. The 200150-21-05 uses a 3/8-24 female mounting thread. Ensure the mounting surface is clean, flat, and free of paint or debris. Apply the recommended mounting torque to achieve optimal coupling. For best results, mount the accelerometer directly on the bearing housing or as close to the vibration source as possible. Use the supplied hex plate stud for secure attachment.

Maintenance & Reliability

The 200150-21-05 is built with a robust design that requires minimal maintenance. Its hermetically sealed construction protects against moisture and contaminants. For reliable operation, periodically inspect the cable and connector for damage. Verify that the mounting remains tight, especially in high-vibration environments. The accelerometer's ceramic sensing element and shear geometry provide long-term stability.

Selection Guide & Purchasing Advice

Before purchasing the 200150-21-05, verify that your system supports Trendmaster 2000 or Trendmaster Pro accelerometers. Confirm the mounting thread compatibility with your installation.
