200150-19-05 | Bently Nevada 10.2 mV/(m/s²) Accelerometer

Introduction: Solving Vibration Monitoring Challenges

When machinery vibration threatens uptime, the 200150-19-05 from Bently Nevada offers a robust solution. This General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer is designed for general applications where accurate acceleration measurement is critical. With a sensitivity of 10.2 mV/(m/s²) at 80 Hz, it captures subtle vibrations that can indicate early wear or imbalance.

Key Features & Technical Specs

Every specification of the 200150-19-05 is engineered for precision and durability in industrial environments.

• Sensitivity: 10.2 mV/(m/s²) at 80 Hz, ±12%.

• Frequency Range: 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz.
• Mounted Resonant Frequency: >20 kHz.
• Excitation Voltage: 4.7 to 5.5 Vdc.
• Output Bias Voltage: +2.5 ± 0.23 Vdc.
• Temperature Range: -40°C to +105°C.
• Sealing: Hermetic, 5×10⁻⁸ atm·cc/s maximum.
• Weight: 58 g (2.0 oz), typical.
• Housing Material: 316L stainless steel.

One distinctive spec is the mounted resonant frequency exceeding 20 kHz, which ensures accurate readings even in high-frequency applications without structural interference.

Industry Applications & Use Cases

In rotating machinery such as pumps, fans, and compressors, the 200150-19-05 provides early fault detection. For example, in a petrochemical plant, this accelerometer can monitor bearing health to prevent unplanned shutdowns. Its wide temperature range and hermetic sealing make it suitable for harsh environments, including condensing humidity. The device is also ideal for general vibration monitoring in manufacturing lines where consistent data is essential for predictive maintenance programs.

Installation & Setup

Mount the 200150-19-05 using the 3/8-24 female thread and apply a torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The Quick-Set XDCR adapter (mounting stud option 19) simplifies alignment. Ensure the base is clean and flat for optimal signal transfer. After mounting, allow up to 24 hours for the adhesive cure if using the recommended mounting compound. Connect the excitation voltage between 4.7 and 5.5 Vdc, and verify the output bias voltage is within +2.5 ± 0.23 Vdc.

Maintenance & Reliability

To maximize service life, inspect the 200150-19-05 periodically for physical damage or corrosion. The 316L stainless steel housing resists environmental stress, but cable connections should be checked for wear. Given the hermetically sealed design, no internal maintenance is required. Regular calibration checks against a known reference ensure measurement accuracy over time. This low-maintenance approach reduces total cost of ownership, aligning with the cost-benefit angle of long-term reliability.

Compatibility & Integration

The 200150-19-05 integrates with Bently Nevada ProTIM systems using the Standard Acceleration-to-Velocity channel type (-01). It is compatible with Trendmaster 2000 and Trendmaster Pro platforms. The multiple approvals (CSA, ATEX, and IECEx) ensure it meets global safety standards for hazardous locations. For best results, pair it with Bently Nevada data acquisition modules that support IEPE-style accelerometers.

Troubleshooting & Common Issues

If output bias voltage drifts outside +2.5 ± 0.23 Vdc, check the excitation supply and cable integrity. A quiescent current above 800 µA may indicate a damaged sensor. For erratic readings, verify the mounting torque and that the base is free of debris. Refer to the Bently Nevada manual for detailed diagnostics.
