Product Overview

The Bently Nevada 330180-51-CN is a high-performance signal conditioning module engineered for the 3300 XL Proximity Transducer System. This specific "CN" variant is designed for DIN-rail mounting, offering a space-efficient solution for modular control cabinets. It serves as the primary interface in a displacement measurement chain, providing excitation to the proximity probe and converting eddy-current signals into a linear voltage output.

This Proximitor sensor is calibrated for a total system length of 5.0 meters (16.4 feet). By generating an output voltage directly proportional to the gap between the probe tip and the conductive target, the 330180-51-CN enables simultaneous monitoring of dynamic radial vibration and static axial shaft position. It is an essential component for Turbine Supervisory Instrumentation (TSI) in high-speed industrial environments.

Technical Characteristics and Construction

• API 670 Standard Compliance: Fully adheres to the American Petroleum Institute's benchmarks for linearity, frequency response (0.5 Hz to 12 kHz), and thermal stability.

• Eddy-Current Precision: Utilizes advanced sensing technology to provide non-contact measurement of rotating shafts with a standard scale factor of 7.87 V/mm (200 mV/mil).

• Modular Installation: The DIN-rail mount configuration and integrated screw-clamp terminals facilitate rapid, secure wiring in high-density cabinet layouts.

• System Interchangeability: Designed to allow the replacement of probes or extension cables within the 3300 XL series without requiring time-consuming manual bench calibration.

• Industrial Ruggedness: Features a wide operating temperature range from -40°C to +85°C and robust shielding against electromagnetic interference (EMI).

• Diagnostics and Safety: Includes a built-in LED status indicator for real-time operational feedback and supports seamless integration with Bently Nevada 3500 monitoring racks.
