128277-01

Bently Nevada 3500 Series Proximitor Signal Conditioner Module (Model: 128277-01)

(Model Naming Interpretation:

128277: Bently Nevada’s global product identification code for 3500 Series signal conditioning modules, ensuring compatibility with the 3500 Monitoring System (e.g., 3500/20 frame, 3500/32 display unit).

-01: Hardware revision suffix, indicating the first production variant (optimized for signal stability and EMC immunity compared to early prototypes).

Core Positioning: The “signal processing hub for rotating machinery monitoring,” converting raw eddy-current sensor signals into standardized, usable data (e.g., displacement, vibration amplitude) for the 3500 System—enabling real-time condition monitoring and fault detection for critical rotating equipment. )

2. Product Description

The 128277-01 is a dedicated signal conditioner module developed by Bently Nevada for the 3500 Monitoring System, featuring “high-precision signal conditioning, industrial-grade reliability, seamless system integration, and comprehensive fault diagnosis” as its core characteristics. It is primarily used in scenarios such as turbine rotor displacement monitoring in power plants, generator vibration measurement in utilities, and compressor shaft position control in petrochemical facilities. Its core value lies in solving the challenges of weak raw sensor signals, electromagnetic interference (EMI) in harsh industrial environments, and inconsistent signal formats—ensuring accurate, reliable data for machinery protection and predictive maintenance. Key advantages are reflected in four areas:

2.1 High-Precision Proximitor Signal Processing

Eddy-Current Sensor Compatibility: Specifically designed to work with Bently Nevada’s 3300/3500 Series proximitor sensors (e.g., 330105, 330180), supporting both 5 mm and 8 mm probe ranges. It provides a regulated -24 V DC excitation voltage to power proximitors, ensuring stable sensor performance (excitation voltage accuracy: ±0.5%).

Signal Conditioning & Linearization: Converts raw eddy-current sensor signals (non-linear impedance variations) into linearized DC voltage outputs (0-10 V DC) or current outputs (4-20 mA) proportional to physical parameters (e.g., rotor displacement, vibration peak-to-peak amplitude). The linearization error is ≤±0.5% of full scale (FS), ensuring measurement accuracy for critical parameters (e.g., turbine shaft runout ≤0.01 mm).
