200150-01-05 | Bently Nevada 100 mV/g Accelerometer General Purpose Trendmaster

Introduction to the Bently Nevada 200150-01-05

When machinery vibration threatens uptime, the 200150-01-05 from Bently Nevada delivers precise measurement. This General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer is engineered for continuous monitoring in industrial environments. With a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, it captures critical vibration data. The accelerometer supports applications requiring ±245 m/s² (±25 g) measurement range. Its compact design and robust construction make it a reliable choice for predictive maintenance programs.

Real-World Applications for the 200150-01-05

In rotating machinery monitoring, the 200150-01-05 excels at detecting early bearing faults and imbalance. It is commonly used in pumps, fans, compressors, and motors within oil and gas, power generation, and manufacturing. The accelerometer's wide temperature range (-40 °C to +105 °C) allows deployment in outdoor or high-temperature areas. Its multiple approvals (CSA, ATEX, IECEx) make it suitable for hazardous locations where safety is critical.

Installation & Setup Guide

Mount the 200150-01-05 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 01 includes two adhesive mount frames with adhesive. Ensure the mounting surface is clean and flat for optimal coupling. Connect the excitation voltage between 4.7 and 5.5 Vdc, observing correct polarity (SIG+ positive with respect to SIG-). Allow 24 hours cure time for adhesive mounts before operation.

Maintenance & Reliability Tips

Regular inspection of the accelerometer and its cable connections helps prevent signal degradation. Check for physical damage or corrosion on the 316L stainless steel housing. The hermetic seal maintains integrity under high humidity (100% condensing). Periodically verify output bias voltage (2.5 ± 0.23 Vdc) to confirm proper operation. Following these steps reduces unplanned downtime and extends sensor life.

Comparison with Similar Accelerometers

Compared to standard industrial accelerometers, the 200150-01-05 offers higher sensitivity (100 mV/g) and a wider frequency range (10-1000 Hz). Many general-purpose sensors have lower resonant frequencies or narrower temperature limits. The Bently Nevada unit provides superior linearity (±2%) and low transverse sensitivity (≤7%). Its multiple certifications (CSA, ATEX, IECEx) are often absent in competing models, making it a preferred choice for hazardous area installations.
