Bently Nevada 330104-00-04-10-11-00 3300 XL Proximity Probe

Description

Monitoring shaft vibration and position in critical rotating machinery requires high-precision displacement measurements, which are delivered by the 330104-00-04-10-11-00 proximity probe. This sensor is an integral component of the industry-standard Bently Nevada 3300 XL 8 mm Series transducer system. By establishing a non-contacting measurement relative to a conductive target, it ensures continuous, high-accuracy tracking of radial vibration, axial position, and speed indicators.

This specific configuration features an M10 x 1 metric thread and is built with integral stainless steel armor to shield the coaxial cable against mechanical damage and harsh operating environments. Designed for seamless integration, it pairs directly with a 3300 XL Proximitor Sensor to output a linear voltage proportional to the distance between the probe tip and the monitored shaft surface.

Features

• Enhanced Cable Protection: Equipped with robust stainless steel armor to prevent pinching, abrasion, and cutting in demanding industrial installations.
• Fluid Migration Resistance: Built utilizing FluidLoc coaxial cable to restrict fluid bypass through the interior of the probe cable.
• Premium Tip Material: The probe tip is molded from polyphenylene sulfide (PPS), offering chemical inertness and stability across high temperature ranges.
• Secure Connector Interface: Includes a miniature coaxial connector with a pre-installed connector protector to guard against moisture ingress and physical disruption.
• Full System Integration: Fully compatible with Bently Nevada 3300 XL series calibration curves and standard mounting brackets.

Applications

• Turbine shaft radial vibration and axial thrust position monitoring.
• Keyphasor and phase reference measurements on high-speed rotors.
• Eccentricity and casing expansion tracking in steam and gas turbines.
• Vibration diagnostics in heavy-duty industrial compressors, pumps, and gearboxes.

Technical Specifications

Installation Guidelines

• Target Alignment: Ensure the target material is standard AISI 4140 steel for optimal factory calibration. If other materials are used, target recalibration is required.
• Clearance Requirements: Maintain a minimum of 15.2 mm (0.6 inches) diameter of cleared space around the probe tip to prevent side-loading or cross-talk interference from surrounding metal.
• Connector Care: Keep coaxial connectors clean and dry during installation. Use the provided connector protector to seal the connection against environmental contaminants.
• Armor Routing: Route the armored cable carefully to avoid exceeding the minimum bend radius of 25.4 mm (1.0 inch).
