What Is the Bently Nevada 200150-05-CN?
When machinery vibration threatens uptime, the Bently Nevada 200150-05-CN General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer delivers reliable data for condition monitoring. This accelerometer combines a ceramic shear sensing element with a rugged 316L stainless steel housing, making it suitable for general industrial applications. Manufactured in the U.S.A., the 200150-05-CN is designed for use with the ProTIM Option Standard Acceleration-to-Velocity channel type (-01).
Technical Specifications Breakdown
Understanding key parameters helps you select the right sensor. The 200150-05-CN offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a ±12% tolerance. Its measurement range spans ±245 m/s² (±25 g), covering typical vibration levels in rotating machinery. The frequency range of 10 to 1000 Hz (600 to 60,000 cpm) suits common fault frequencies like imbalance and misalignment. With a mounted resonant frequency above 20 kHz, this accelerometer avoids resonance interference in most applications.
Amplitude linearity stays within ±2% for 1 to 10 g pk, ensuring accurate readings across the operating range. Transverse sensitivity is ≤7%, minimizing cross-axis errors. The output bias voltage sits at +2.5 ± 0.23 Vdc, and quiescent current remains below 800 µA. Excitation voltage ranges from 4.7 to 5.5 Vdc, compatible with standard data collectors.
Industry Applications
In petrochemical plants, the 200150-05-CN monitors pumps and compressors for early signs of bearing wear. Its 100% relative humidity rating (condensing, non-submerged) allows deployment in washdown areas. For power generation, the accelerometer tracks turbine vibrations from 10 to 1000 Hz, capturing both low-speed and high-speed issues. The -40 °C to +105 °C temperature range suits outdoor installations in cold climates or near hot machinery.
Installation & Setup Guidance
Mount the 200150-05-CN 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 05 specifies a 3/8-24 to 1/4-28 UNF 1-3/8 inch hex plate stud. Ensure the mounting surface is clean and flat for optimal signal transfer. After installation, allow 24 hours cure time if adhesive mounting is used. Connect SIG+ positive with respect to SIG- for proper polarity when acceleration is applied from base to connector.
Maintenance & Reliability
Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive environments. The hermetic sealing (5X10⁻⁸ atm•cc/s maximum) protects internal components from moisture and contaminants. Although the accelerometer withstands axial shock up to 49,050 m/s² pk (5,000 g pk), avoid repeated impacts. Regular calibration checks ensure the sensitivity remains within ±12% of the specified 10.2 mV/(m/s²).
Selection Guide & Purchasing Advice
Before ordering, verify that the 200150-05-CN matches your monitoring system's excitation voltage (4.7 to 5.5 Vdc) and input requirements. The CN approval code indicates country-specific certifications. SpareTechPLC stocks this model and can confirm current lifecycle status and availability.
