Bently Nevada 200150-04-05 General Purpose Accelerometer for Trendmaster 2000/Pro

Product Overview

When reliable vibration monitoring is critical for rotating machinery, the Bently Nevada 200150-04-05 provides a robust sensing solution. This general purpose accelerometer is designed for use with Trendmaster 2000 or Trendmaster Pro systems, delivering accurate acceleration measurements in demanding industrial environments. With multiple approvals including CSA, ATEX, and IECEx, it meets rigorous safety standards for hazardous area applications.

Key Specifications

The 200150-04-05 features a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a measurement range of ±245 m/s² (±25 g). Its frequency range spans 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), ensuring high-frequency response. Amplitude linearity is ±2% (1 to 10 g pk), and transverse sensitivity is ≤7%. Settling time is ≤300 ms within 5% of bias. Excitation voltage ranges from 4.7 to 5.5 Vdc, with quiescent current less than 800 µA and output bias voltage of +2.5 ± 0.23 Vdc.

Industry Applications

This accelerometer excels in general purpose vibration monitoring for pumps, fans, compressors, and motors. In a typical petrochemical plant, the 200150-04-05 mounts directly on bearing housings to detect early signs of imbalance or misalignment. Its rugged design withstands harsh conditions, making it suitable for continuous monitoring in refineries and power generation facilities.

Installation & Setup Guidance

Mount the 200150-04-05 using the provided 3/8-24 female thread with a mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option 04 includes a 3/8-24 to 1/4 NPT 1-3/8 inch hex plate stud for secure attachment. Ensure the mounting surface is clean and flat to achieve optimal frequency response. Allow 24 hours cure time for adhesive mounting if applicable. Connect the accelerometer to a compatible Trendmaster 2000 or Trendmaster Pro system using the appropriate cable.

Maintenance & Reliability

Routine inspection of the accelerometer and its mounting is recommended to ensure reliable performance. The hermetically sealed 316L stainless steel housing provides excellent protection against moisture and contaminants, with a sealing rating of 5x10⁻⁸ atm·cc/s maximum. The ceramic shear sensing element offers long-term stability. Operating temperature range is -40 °C to +105 °C (-40 °F to +221 °F), with storage capability from -55 °C to +121 °C (-67 °F to +250 °F).

Comparison with Similar Models

Compared to standard industrial accelerometers, the 200150-04-05 offers a higher mounted resonant frequency (>20 kHz) and wider frequency range, making it suitable for high-speed machinery. Its multiple approvals (CSA, ATEX, IECEx) distinguish it from models with single certifications, simplifying compliance across global facilities. The low quiescent current (<800 µA) ensures minimal power draw in multi-channel systems.

Selection Guide & Purchasing Advice

Before purchasing the Bently Nevada 200150-04-05, verify compatibility with your Trendmaster 2000 or Trendmaster Pro system. Confirm the mounting thread (3/8-24 female) and environmental conditions (temperature, humidity) meet your application requirements.
