200150-13-05 | Bently Nevada 100 mV/g Accelerometer Trendmaster

Introduction to the Bently Nevada 200150-13-05 Accelerometer

When vibration monitoring demands precision and durability, the 200150-13-05 from Bently Nevada offers a cost-effective 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) (100 mV/g) at 80 Hz, it provides consistent data for predictive maintenance programs. The unit is made in the U.S.A. and comes with multiple approvals (CSA, ATEX, and IECEx), reducing compliance costs across different regions.

Applications and Use Cases

In rotating machinery monitoring, the 200150-13-05 excels at capturing vibration signatures from bearings, gears, and shafts. Its wide frequency range (10 to 1000 Hz) suits fans, pumps, motors, and compressors. The multiple approvals (CSA, ATEX, IECEx) allow deployment in hazardous environments without additional certification expenses. For example, a chemical plant can use this accelerometer to monitor pump vibrations, preventing catastrophic failures and saving thousands in emergency repairs.

Installation and Setup

Mount the accelerometer using the 3/8-24 female thread and apply a mounting torque between 2.7 and 6.8 N·m (2 to 5 ft·lbf). Ensure the mounting surface is clean and flat for optimal coupling. The 3/8-24 to 5/16-18 UNC stud option (mounting stud option 13) simplifies integration with existing hardware. After installation, allow 24 hours cure time for the adhesive if used. Verify the output bias voltage is within +2.5 ± 0.23 Vdc to confirm proper operation.

Maintenance and Reliability

Routine inspection of the accelerometer and its cable connections helps maintain signal integrity. The 316L stainless steel housing resists corrosion, extending service life in harsh environments. With a hermetic seal of 5×10⁻⁸ atm·cc/s, moisture ingress is minimized, reducing replacement frequency. This reliability translates to lower total cost of ownership over the equipment's lifespan.

Compatibility and Integration

The 200150-13-05 is designed for use with ProTIM Option Standard Acceleration-to-Velocity channel type (-01). It works with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. The accelerometer outputs a positive signal (SIG+ positive with respect to SIG-) for acceleration from base to connector, ensuring straightforward integration with compatible monitoring hardware.
