Product Overview
When fin-fan and slow-rotating shaft applications demand reliable vibration monitoring, the Bently Nevada 200155-20-05 Low Frequency Trendmaster Pro accelerometer provides a cost-effective solution. This sensor, part of the Trendmaster Pro series, integrates seamlessly with ProTIM option Low Frequency Acceleration-to-Velocity channel types, reducing installation complexity and long-term maintenance expenses.
Technical Specifications Breakdown
The 200155-20-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring accurate readings for low-frequency vibrations. Its measurement range spans ±196 m/s² (±20 g), making it suitable for moderate vibration levels. The frequency range from 1.5 to 10,000 Hz (90 to 600,000 cpm) covers critical low-speed machinery. With a mounted resonant frequency above 20 kHz, this accelerometer avoids resonance interference, enhancing data reliability. The quiescent current stays below 800 µA, minimizing power consumption and operational costs.
Industry Applications
This accelerometer excels in fin-fan and slow-rotating shaft environments, where low-frequency vibrations dominate. By detecting early signs of bearing wear or imbalance, the 200155-20-05 helps prevent unplanned downtime, directly improving return on investment. Its multiple approvals (CSA, ATEX, and IECEx) allow deployment in hazardous areas without additional certification costs.
Installation & Setup Guidance
Mount the 200155-20-05 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 included magnetic mount base simplifies temporary installations. Ensure the excitation voltage stays between 4.7 and 5.5 Vdc to maintain output bias voltage at +2.5 ± 0.23 Vdc. Proper mounting reduces signal noise and extends sensor life.
Maintenance & Reliability
The 200155-20-05 features a hermetically sealed 316L stainless steel housing, protecting against harsh environments. With a temperature range of -40 °C to +105 °C (-40 °F to +221 °F) and 100% relative humidity tolerance, it withstands demanding conditions. Periodic inspection of the mounting thread and cable connections ensures consistent performance, reducing replacement frequency and total cost of ownership.
