Product Overview

The Bently Nevada 330180-X1-05, featuring the MOD:145004-13 factory modification, is a high-precision signal conditioning module designed for the 3300 XL 8 mm Proximity Transducer System. This Proximitor sensor acts as the electronic heart of a non-contacting displacement measurement chain. It provides the necessary excitation for proximity probes and converts the resulting eddy-current impedance changes into a linear voltage signal. This output is directly proportional to the gap between the probe tip and the target shaft, enabling high-fidelity monitoring of radial vibration and axial position.

This module is specifically engineered to meet the stringent American Petroleum Institute (API) 670 standards, ensuring peak performance in critical Turbine Supervisory Instrumentation (TSI) applications. The 3300 XL series is renowned for its "plug-and-play" architecture, allowing for the complete interchangeability of sensors, extension cables, and probes without the labor-intensive requirement for manual bench calibration or component matching.

Technical Characteristics and Performance

• API 670 Compliance: Fully adheres to industry standards for linear range, accuracy, and thermal stability, making it suitable for permanent installation on high-speed rotating assets.

• System Interchangeability: Designed to allow replacement of any system component (probe, cable, or sensor) while maintaining a standard scale factor of 7.87 V/mm (200 mV/mil).

• Enhanced RFI/EMI Immunity: The circuitry is shielded to resist electromagnetic interference, allowing for installation in fiberglass enclosures or near high-frequency noise sources without signal degradation.

• Backward Compatibility: Electrically compatible with legacy non-XL 3300 series 5 mm and 8 mm components, facilitating cost-effective upgrades of older monitoring systems.

• Ruggedized Construction: Features a robust housing designed for industrial environments, protecting the internal 32-bit processing capabilities and signal conditioning electronics.

• Self-Isolating Mounting Base: The integrated base provides electrical isolation, which eliminates the need for separate isolator plates and simplifies the grounding architecture within the control cabinet.
