Bently Nevada 200155-18-CN Low Frequency Trendmaster Pro Accelerometer

Product Introduction

The Bently Nevada Low Frequency Trendmaster Pro Accelerometer (Model: 200155-18-CN) is a precision vibration sensor specifically designed for low-frequency condition monitoring in industrial machinery. It is part of the Trendmaster Pro system, which is widely used for continuous condition-based monitoring and predictive maintenance applications.

This accelerometer is optimized to detect low-frequency vibration signals that are often associated with structural issues, imbalance, misalignment, and early-stage mechanical faults. Compared with standard accelerometers, it provides improved sensitivity in the lower frequency range, making it particularly suitable for slow-speed and medium-speed equipment.

With its compact and lightweight design, the sensor can be easily installed on various machine surfaces. It offers reliable signal output and strong resistance to environmental interference, ensuring stable long-term operation in industrial environments such as power plants, petrochemical facilities, and manufacturing systems.

FAQ

1. What makes this accelerometer suitable for low-frequency monitoring?
   It is specifically engineered with enhanced sensitivity in the low-frequency range, allowing it to detect slow and subtle vibration signals that standard accelerometers may not capture effectively.
2. How does this sensor differ from a standard accelerometer?
   Unlike general-purpose accelerometers, this model prioritizes low-frequency response, making it more effective for detecting structural issues and slow-speed machinery faults.
3. Where is the optimal installation point for this sensor?
   It should be mounted on rigid surfaces such as bearing housings or structural components where vibration transmission is most representative of machine condition.
4. Can it be used for high-speed machinery?
   While it can operate on high-speed equipment, its primary advantage lies in low-frequency applications, so it is best suited for slow to medium-speed machinery.
5. What type of signal output does it provide?
   It outputs an analog voltage proportional to acceleration, which can be processed by monitoring systems for analysis.
6. How does mounting affect measurement accuracy?
   A secure and rigid mounting method ensures better signal transmission and accuracy, while loose mounting can introduce measurement errors.
7. Is the sensor resistant to industrial environmental conditions?
   Yes, it features a sealed housing designed to withstand dust, moisture, and temperature variations.
8. Does the sensor require calibration?
   It is typically factory-calibrated, but periodic verification may be recommended depending on application requirements.
9. What types of faults can this sensor help detect?
   It is effective in identifying imbalance, misalignment, looseness, structural resonance, and early-stage mechanical degradation.
10. How is this sensor integrated into a monitoring system?
    It connects to a Trendmaster Pro system or compatible monitoring equipment, where the signal is analyzed for condition-based maintenance.
