Bently Nevada 200150-21-05 General Purpose Accelerometer Overview

Product Introduction

When unexpected machinery vibrations threaten production uptime, the Bently Nevada 200150-21-05 provides reliable, high-accuracy acceleration measurement. This General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer is designed for continuous monitoring in harsh industrial environments. With multiple global approvals (CSA, ATEX, and IECEx), it meets stringent safety and performance standards, making it a trusted choice for plant-wide vibration monitoring programs.

Technical Specifications Breakdown

The 200150-21-05 delivers a mounted resonant frequency exceeding 20 kHz (>1200 kcpm), ensuring excellent high-frequency response for early fault detection. Its quiescent current is less than 800 µA, contributing to low power consumption in multi-sensor installations. The mounting stud option (21) features a 3/8-24 outer diameter to M6x1 inner diameter with a 1-3/8 inch hex plate stud, simplifying installation on various machine surfaces.

Industry Applications

This accelerometer excels in general-purpose vibration monitoring of rotating equipment such as pumps, fans, compressors, and motors. In a typical refinery application, the 200150-21-05 mounts directly on bearing housings to capture early signs of imbalance or misalignment. Its hermetically sealed construction withstands 100% condensing humidity, making it suitable for washdown areas and outdoor installations. The multiple approvals (CSA, ATEX, IECEx) allow deployment in hazardous locations without additional certification burdens.

Installation & Setup Guidance

Mount the 200150-21-05 using the provided 3/8-24 female thread. Apply the specified mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) for consistent coupling. Ensure the mounting surface is clean and flat to achieve optimal frequency response. Connect the accelerometer to a compatible Trendmaster 2000 or Trendmaster Pro monitor using shielded cable, observing proper polarity (SIG+ positive with respect to SIG-). Allow 24 hours cure time for any adhesive mounting if used.

Maintenance & Reliability

Routine inspection of the accelerometer and its cable is recommended to verify physical integrity and secure connections. The 316L stainless steel housing and ceramic shear sensing element provide excellent corrosion resistance and long-term stability. Although the sensor is hermetically sealed, periodic verification of output bias voltage ensures the internal electronics remain within specification. Follow manufacturer guidelines for any cleaning or recalibration needs.

Selection Guide & Purchasing Advice

Before ordering the 200150-21-05, verify your system compatibility: it works with Trendmaster 2000 and Trendmaster Pro monitors using Standard Acceleration-to-Velocity channel type (-01). Confirm the mounting stud option (21) matches your machine’s thread pattern. For complete technical specifications, please contact BluePLC Industrial.
