200150-06-05 | Bently Nevada 100 mV/g General Purpose Accelerometer

Introduction to the Bently Nevada 200150-06-05 Accelerometer

When precise vibration monitoring is critical for machinery health, the 200150-06-05 from Bently Nevada provides a trusted solution. This general purpose accelerometer is part of the Trendmaster 2000 and Trendmaster Pro families, engineered for continuous condition monitoring. With a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, it captures subtle vibration changes that indicate developing faults. The unit features multiple approvals including CSA, ATEX, and IECEx, making it suitable for hazardous environments. Its 316L stainless steel housing ensures durability in demanding industrial settings.

Real-World Applications and Use Cases

In rotating machinery monitoring, the 200150-06-05 excels at detecting imbalance, misalignment, and bearing wear. Its ±25 g range covers most general-purpose vibration levels found in pumps, fans, compressors, and motors. The accelerometer works seamlessly with Bently Nevada ProTIM systems using standard acceleration-to-velocity channel types. For engineers upgrading from older sensors, this model offers improved linearity and faster settling time, reducing measurement uncertainty. The multiple approval options simplify compliance in global installations, from oil and gas to power generation.

Installation and Setup Guidance

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) to ensure proper coupling. The mounting stud option 06 provides a 3/8-24 to 1/4 NPT adapter with a 3/4 inch hex stud for secure attachment. Apply a thin layer of silicone grease to the mounting surface for optimal high-frequency response. Allow 24 hours cure time for the adhesive if used. Connect the SIG+ and SIG- wires per the polarity marking: SIG+ positive with respect to SIG- for acceleration from base to connector. Verify excitation voltage between 4.7 and 5.5 Vdc before powering the sensor.

Maintenance and Reliability Tips

Regular inspection of the accelerometer’s mounting integrity and cable condition ensures consistent performance. The hermetic sealing (5×10⁻⁸ atm·cc/s) protects against moisture ingress, even in condensing humidity environments. With a wide temperature range of -40 °C to +105 °C, the sensor withstands thermal cycling without degradation. The ceramic shear sensing element offers long-term stability, reducing recalibration frequency. For critical machinery, periodic verification of bias voltage and sensitivity per the manufacturer’s guidelines is recommended.

Compatibility and Integration

The 200150-06-05 is designed for use with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. It supports standard acceleration-to-velocity channel types (-01 option) for seamless data integration. The multiple approvals (CSA, ATEX, IECEx) allow deployment in classified areas without additional barriers. The sensor’s 100 mV/g output is compatible with most industrial data collectors and vibration analyzers that accept IEPE-type inputs.
