Bently Nevada 200155-05-CN Low Frequency Trendmaster Pro Accelerometer

Product Introduction

When monitoring slow rotating shafts or fin-fan applications, the Bently Nevada 200155-05-CN Low Frequency Trendmaster Pro Accelerometer delivers reliable vibration data. This sensor is designed for low-frequency measurements, making it suitable for machinery where traditional accelerometers may struggle. Manufactured in the USA, it features a ceramic shear sensing element and a 316L stainless steel housing for durability in harsh environments.

Technical Specifications Breakdown

Key specifications of the 200155-05-CN include a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring accurate output for low-level vibrations. Its mounted resonant frequency exceeds 20 kHz (>1200 kcpm), providing a wide frequency range for reliable data. The quiescent current is less than 800 µA, indicating low power consumption. With a measurement range of ±196 m/s² (±20 g), it handles typical industrial vibration levels effectively.

Industry Applications

This accelerometer excels in monitoring slow rotating shafts, such as those found in fin-fan coolers, cooling towers, and other low-speed rotating equipment. Its low-frequency response (1.5 to 10,000 Hz) makes it ideal for detecting early signs of bearing wear or imbalance in machinery operating below 600 RPM. Compared to standard accelerometers, the 200155-05-CN offers superior sensitivity below 10 Hz, reducing the risk of missed faults.

Installation & Setup Guidance

The 200155-05-CN mounts using a 3/8-24 female thread, with a recommended mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The -05 option includes a 3/8-24 to 1/4-28 UNF stud with a 1-3/8 inch hex plate for secure attachment. Ensure the mounting surface is clean and flat to achieve optimal frequency response. The sensor operates on an excitation voltage of 4.7 to 5.5 Vdc, and its output bias voltage is +2.5 ± 0.23 Vdc.

Maintenance & Reliability

Routine inspection of the accelerometer's cable and connector is recommended to maintain signal integrity. The hermetically sealed design (5x10⁻⁸ atm·cc/s maximum leak rate) protects against moisture and contaminants, ensuring long-term reliability in condensing humidity environments. With a temperature range of -40 ºC to +105 ºC, it withstands extreme conditions common in outdoor fin-fan applications.

Buying Guide & Selection Advice

When selecting the 200155-05-CN, verify that your monitoring system supports the accelerometer's sensitivity and excitation voltage. The CN approval indicates country-specific certifications; confirm compatibility with your regional requirements.
