Real-World Applications

In industries like oil and gas, power generation, and manufacturing, the 200150-23-05 excels at monitoring pumps, compressors, fans, and motors. Its wide frequency range captures both low-speed and high-speed vibrations, enabling early detection of bearing wear, imbalance, or misalignment. For example, in a petrochemical plant, this accelerometer can help avoid unplanned downtime by providing continuous data to a Trendmaster system.

With multiple approvals (CSA, ATEX, and IECEx), the 200150-23-05 is certified for use in hazardous locations, making it a versatile choice for safety-critical environments.

Installation & Setup Guidance

Mount the 200150-23-05 using its 3/8-24 female thread and apply a torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The mounting stud option 23 includes a 3/8-24 to M16x2.0 1-3/8 inch hex plate stud. Ensure the mounting surface is clean and flat to achieve optimal frequency response. The accelerometer uses a 4.7 to 5.5 Vdc excitation supply, with signal positive relative to signal negative.

For best results, follow the manufacturer's installation manual and verify the output bias voltage is within +2.5 ± 0.23 Vdc after setup.

Maintenance & Reliability Tips

Routine inspection of the 200150-23-05 should focus on cable integrity and mounting tightness. The 316L stainless steel housing resists corrosion, and the hermetic seal protects internal components. Periodically verify the output bias voltage and quiescent current (<800 µA) to detect any drift. This proactive approach minimizes downtime and extends sensor life.

Compatibility & Integration

The 200150-23-05 is designed for use with Bently Nevada Trendmaster 2000 or Trendmaster Pro systems. It works with the ProTIM option Standard Acceleration-to-Velocity channel type (-01) for velocity data. The accelerometer's 100 mV/g sensitivity integrates seamlessly with standard monitoring modules.
