200150-03-05 | Bently Nevada 10.2 mV/(m/s²) Accelerometer

Introduction to the Bently Nevada 200150-03-05 Accelerometer

When machinery vibration threatens uptime, the 200150-03-05 from Bently Nevada provides reliable measurement. This General Purpose Trendmaster 2000 or Trendmaster Pro accelerometer is engineered for continuous monitoring in industrial environments. With a sensitivity of 10.2 mV/(m/s²) at 80 Hz, it captures critical vibration data accurately. The unit supports multiple approvals including CSA, ATEX, and IECEx, making it suitable for hazardous locations. Its compact design and robust construction ensure long-term performance in demanding applications.

Core Specifications and Performance Metrics

The 200150-03-05 offers a measurement range of ±245 m/s² (±25 g) and a frequency range of 10 to 1000 Hz (600 to 60,000 cpm). Key electrical parameters include:

• Sensitivity: 10.2 mV/(m/s²) (100 mV/g) ±12% at 80 Hz
• Excitation voltage: 4.7 to 5.5 Vdc
• Quiescent current: <800 µA
• Output bias voltage: +2.5 ± 0.23 Vdc
• Settling time: ≤300 ms

These specs ensure consistent signal output for vibration analysis. The ceramic shear sensing element provides excellent linearity (±2% from 1 to 10 g pk) and low transverse sensitivity (≤7%).

Applications and Use Cases

In rotating machinery applications, the 200150-03-05 excels at detecting early signs of imbalance, misalignment, or bearing wear. It is ideal for pumps, fans, compressors, and motors where reliable vibration data is critical. The accelerometer's wide temperature range (-40°C to +105°C) and hermetic sealing (5×10⁻⁸ atm·cc/s max) make it suitable for harsh environments including chemical plants and refineries. Its multiple approvals simplify compliance with international safety standards.

Installation and Mounting Guidance

Proper mounting is essential for accurate readings. The 200150-03-05 uses a 3/8-24 female thread and requires a mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The included stud option (03) adapts to 3/8-24 to 1/2-20 UNF with a 1-3/8 inch hex plate. Ensure the mounting surface is clean and flat to achieve optimal frequency response. After installation, allow 24 hours for the adhesive cure if using a bonding method. Always follow the manufacturer's manual for detailed wiring and setup procedures.

Maintenance and Reliability Tips

To maintain accuracy, inspect the 200150-03-05 periodically for physical damage or contamination. The 316L stainless steel housing resists corrosion in most industrial environments. Check cable connections and ensure the mounting torque remains within spec. Avoid exposing the sensor to axial shock exceeding 49,050 m/s² pk (5,000 g pk). Regular verification of bias voltage and sensitivity helps detect drift early. For safety-rated installations, follow the manufacturer's maintenance schedule.

Compatibility and Integration

The 200150-03-05 works with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. It is designed for use with ProTIM option standard acceleration-to-velocity channel type (-01). The accelerometer outputs a positive signal (SIG+ positive with respect to SIG-) for acceleration from base to connector. Its 4.7 to 5.5 Vdc excitation voltage is compatible with most vibration monitoring modules. For specific system integration details, consult the official Bently Nevada documentation.
