Product Overview

The Bently Nevada 330180-085-03-05 is a high-precision proximity transducer component engineered for the 3300 XL series. Functioning as a critical signal conditioning interface, it translates the physical gap between an 8 mm probe tip and a target shaft into a linear DC voltage. This allows for the simultaneous acquisition of dynamic vibration data and static positional displacement.

Designed specifically for Turbine Supervisory Instrumentation (TSI), this module ensures high-fidelity monitoring of rotating equipment utilizing fluid-film bearings. The 330180-085-03-05 adheres to the American Petroleum Institute (API) 670 standards, guaranteeing exceptional accuracy, thermal stability, and mechanical interchangeability within mission-critical machinery protection environments.

Technical Characteristics and Construction

• Advanced Mechanical Bonding: Utilizes patented TipLoc molding to create an impenetrable seal between the probe tip and the sensor body, preventing moisture ingress and mechanical separation.

• Superior Cable Integrity: Features the CableLoc design, which provides a robust 330 N (75 lbf) pull strength, ensuring the cable remains securely attached even under high-strain industrial conditions.

• Tool-Free Connectivity: Equipped with gold-plated, corrosion-resistant ClickLoc connectors. These specialized connectors allow for finger-tight installation while maintaining a vibration-proof lock that prevents accidental loosening.

• Target Calibration: Standard factory calibration is optimized for AISI 4140 steel. The sensor maintains a consistent Scale Factor of 7.87 V/mm (200 mV/mil), providing linear measurement across its entire range.

• Component Interchangeability: Fully compatible with both XL and non-XL 3300 series 5 mm and 8 mm components. This "universal" design allows for the replacement of individual probes, cables, or sensors without the need for manual bench calibration.

• RFI/EMI Immunity: Engineered to resist electromagnetic interference, allowing for installation in non-metallic housings without signal degradation.
