200150-17-05 | Bently Nevada 100 mV/g Trendmaster Accelerometer

What Is the Bently Nevada 200150-17-05?

When machinery vibration threatens uptime, the 200150-17-05 from Bently Nevada provides accurate, real-time data. This General Purpose Trendmaster 2000 or Trendmaster Pro accelerometer is designed for general application use. It offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring precise measurement across a frequency range of 10 to 1000 Hz (600 to 60,000 cpm). With a measurement range of ±245 m/s² (±25 g), it handles a wide variety of industrial vibration profiles. The unit operates on an excitation voltage of 4.7 to 5.5 Vdc and draws a quiescent current of less than 800 µA. Its output bias voltage sits at +2.5 ± 0.23 Vdc, providing a stable signal for analysis.

Performance Metrics and Core Specs

• Sensitivity: 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ±12%.
• Measurement Range: ±245 m/s² (±25 g).
• Frequency Range: 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz.
• Mounted Resonant Frequency: >20 kHz (>1200 kcpm).
• Amplitude Linearity: ±2% (1 to 10 g pk).
• Transverse Sensitivity: ≤7%.
• Settling Time: ≤300 ms (within 5% of bias).
• Excitation Voltage: 4.7 to 5.5 Vdc.
• Quiescent Current: <800 µA.
• Output Bias Voltage: +2.5 ± 0.23 Vdc.

A standout feature is the settling time of ≤300 ms, which allows the sensor to stabilize quickly after power-up, minimizing data acquisition delays. This is particularly valuable in applications where rapid monitoring startup is critical.

Real-World Applications and Use Cases

In rotating machinery such as pumps, fans, and compressors, the 200150-17-05 excels at early fault detection. For example, a petrochemical plant can use it to monitor bearing wear and imbalance trends, preventing unplanned shutdowns. Its wide temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF) makes it suitable for harsh environments. Additionally, the hermetically sealed design (5x10⁻⁸ atm•cc/s maximum) ensures reliable operation in condensing humidity conditions.

Installation Guide and Mounting Tips

Mount the accelerometer using the 3/8-24 female thread with a torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The mounting stud option 17 provides a 3/8-24 to 3/8-16 UNC 1-3/8 inch hex plate stud for secure attachment. Ensure the mounting surface is clean and flat to achieve optimal frequency response. After installation, allow a 24-hour cure time for any adhesive if used. The unit's compact size (17.5 mm hex x 45.7 mm height) fits easily into tight spaces.

Routine Care and Reliability Tips

To maintain accuracy, inspect the accelerometer periodically for physical damage or contamination. Verify that the mounting torque remains within specification to avoid signal degradation. The 316L stainless steel housing and connector provide excellent corrosion resistance, even in humid or chemically aggressive environments. Regular calibration checks per the manufacturer's guidelines help ensure long-term measurement integrity.

Compatibility and Integration

The 200150-17-05 is designed for use with the ProTIM option Standard Acceleration-to-Velocity channel type (-01). It integrates seamlessly into Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. For system-specific wiring and configuration details, consult the official Bently Nevada documentation or contact Petro Auto Tech.

Troubleshooting and Common Issues

If the output bias voltage deviates beyond +2.5 ± 0.23 Vdc, check the excitation voltage supply (4.7 to 5.5 Vdc). A quiescent current exceeding 800 µA may indicate internal damage. For erratic readings, verify the mounting torque and inspect the cable for breaks. Always follow the manufacturer's safety manual when performing diagnostics.
