Product Overview

The Bently Nevada 330180-51-05 is a high-precision signal conditioning module engineered for the 3300 XL Proximity Transducer System. This Proximitor sensor acts as the electronic core for non-contacting displacement measurements, converting raw eddy-current signals from a proximity probe into a stabilized linear voltage output. The resulting signal is directly proportional to the physical gap between the probe tip and the target conductive surface, such as a machine shaft.

As a fundamental component of Turbine Supervisory Instrumentation (TSI), the 330180-51-05 is designed for high-fidelity monitoring of rotating equipment. It is factory-calibrated to support a 5.0-meter total system length, providing the essential data required for radial vibration analysis, axial thrust position monitoring, and Keyphasor speed sensing on critical assets like steam turbines and centrifugal compressors.

Core Technical Characteristics

• Full API 670 Compliance: Engineered to meet stringent industrial standards for mechanical configuration, linear measurement range, and exceptional thermal stability.

• Eddy-Current Signal Processing: Translates physical shaft movement into a precise analog voltage (standard 200 mV/mil), allowing for real-time monitoring of machinery health.

• Component Interchangeability: Part of the 3300 XL "universal match" architecture, allowing probes, extension cables, and sensors to be swapped without the need for manual bench calibration.

• Rugged Mechanical Interface: Compatible with systems utilizing CableLoc technology, ensuring a 330 N (75 lbf) pull strength to prevent accidental cable detachment in high-vibration environments.

• Superior Environmental Resilience: Designed to operate reliably in harsh industrial climates with an operating temperature range of -40°C to +85°C.

• Enhanced Signal Integrity: Features advanced RFI/EMI shielding to minimize electrical noise interference, ensuring stable data transmission to monitoring racks like the Bently Nevada 3500 series.
