Product Overview

The Bently Nevada 330180-X1-05, featuring the MOD:145004-83 factory modification, is a high-integrity signal conditioning module designed for the 3300 XL 8 mm Proximity Transducer System. This Proximitor sensor acts as the electronic interface for non-contacting displacement measurements, converting the eddy current impedance changes from a proximity probe into a linear voltage output. The resulting signal is directly proportional to the gap distance between the probe tip and the target shaft, enabling high-resolution tracking of both static shaft position and dynamic vibration.

As a primary component in Turbine Supervisory Instrumentation (TSI), the 330180-X1-05 MOD:145004-83 is engineered for maximum reliability on fluid-film bearing machinery. It provides the essential data required for machinery protection systems, supporting radial vibration analysis, axial thrust monitoring, and Keyphasor® speed sensing for phase-related measurements.

Key Technical Characteristics

• API 670 Standard Compliance: Fully adheres to American Petroleum Institute (API) 670 requirements regarding linear range, accuracy, and temperature stability, ensuring suitability for critical industrial machinery protection.

• Component Interchangeability: Designed for seamless "plug-and-play" operation within the 3300 XL series. No bench calibration or manual matching is required when swapping probes, extension cables, or sensors.

• Stable Signal Conditioning: Delivers a consistent scale factor of 7.87 V/mm (200 mV/mil), providing a high signal-to-noise ratio even in electrically challenging industrial environments.

• Advanced RFI/EMI Shielding: Built with robust electronic protection to maintain signal integrity when installed near high-frequency noise sources or within non-metallic enclosures.

• Hazardous Area Readiness: Supported by global certifications (ATEX, IECEx, and CSA) for installation in potentially explosive atmospheres, making it ideal for the oil, gas, and chemical sectors.

• Thermal Resilience: Rated for continuous operation in temperatures ranging from -40°C to +85°C, providing long-term durability in unconditioned machinery rooms.
