200150-14-05 | Bently Nevada 100 mV/g Accelerometer Trendmaster Pro

What Happens When Your Vibration Monitoring Needs Precision?

When machinery health depends on accurate vibration data, the 200150-14-05 from Bently Nevada provides the reliable measurements you need. This general-purpose accelerometer is part of the Trendmaster 2000 or Trendmaster Pro family, designed for continuous condition monitoring in demanding environments. With a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, it captures subtle changes in machine vibration, helping you detect issues before they lead to costly downtime.

Key Features & Technical Specs of the 200150-14-05

• Sensitivity: 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ±12%.
• Measurement Range: ±245 m/s² (±25 g) for acceleration; 14.7 mm/s² (1.5 mg) for low-level vibration.
• Frequency Range: 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz.
• Mounted Resonant Frequency: Greater than 20 kHz (>1200 kcpm).
• Excitation Voltage: 4.7 to 5.5 Vdc.
• Output Bias Voltage: +2.5 ± 0.23 Vdc.
• Quiescent Current: Less than 800 µA.
• Settling Time: ≤300 ms (within 5% of bias).
• Temperature Range: -40 °C to +105 °C (-40 °F to +221 °F).
• Sealing: Hermetic, 5×10⁻⁸ atm•cc/s maximum.
• Housing Material: 316L stainless steel.

A standout feature is the hermetic sealing at 5×10⁻⁸ atm•cc/s, which protects the internal sensing element from moisture and contaminants, making the 200150-14-05 suitable for humid or condensing environments.

Real-World Applications for the 200150-14-05

In rotating machinery such as pumps, fans, compressors, and motors, the 200150-14-05 excels at capturing vibration signatures. Its wide frequency range (10 to 1000 Hz) covers common fault frequencies for imbalance, misalignment, and bearing wear. The accelerometer works with the ProTIM option for standard acceleration-to-velocity channel types, enabling seamless integration into existing Bently Nevada monitoring systems. Because it handles 100% relative humidity (condensing, non-submerged), it is a strong choice for paper mills, chemical plants, and offshore platforms where moisture is a concern.

Installation & Setup Guidance

Mount the 200150-14-05 using the 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 14 provides a 3/8-24 to 3/8-24 UNF stud with a 3/4-inch hex head. Ensure the mounting surface is clean and flat to achieve optimal frequency response. After installation, allow a 24-hour cure time if adhesive mounting is used. The accelerometer settles within 300 ms, so you can begin taking readings shortly after power-up.

Maintenance & Reliability Tips

To maintain the accuracy of the 200150-14-05, inspect the cable and connector periodically for damage. The 316L stainless steel housing resists corrosion, but verify that the mounting torque remains within specification after thermal cycling. Because the accelerometer operates from -40 °C to +105 °C, it can withstand harsh thermal conditions without performance degradation. Regular calibration checks (per manufacturer guidelines) help ensure the sensitivity stays within the ±12% tolerance.

Compatibility & Integration

The 200150-14-05 is designed for use with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. It carries multiple approvals: CSA, ATEX, and IECEx (approval code 05), making it suitable for hazardous area installations. The accelerometer outputs a positive signal (SIG+ positive with respect to SIG-) when acceleration is from base to connector, simplifying wiring polarity checks.

Troubleshooting & Common Issues

If you observe erratic readings, first verify the excitation voltage is between 4.7 and 5.5 Vdc. Check the output bias voltage — it should be +2.5 ± 0.23 Vdc. A bias voltage outside this range may indicate a damaged sensing element or wiring fault. Ensure the mounting torque is correct: over-tightening can distort the housing, while under-tightening reduces frequency response. For persistent issues, consult the Bently Nevada manual or contact Petro Auto Tech for support.
