Bently Nevada 330851-02-000-080-10-00-00 3300 XL 25 mm Proximity Probe

Description

330851-02-000-080-10-00-00 specifies this Bently Nevada 3300 XL 25 mm proximity probe configuration: M30x2 metric threaded case (Option 02), 0.0 mm unthreaded length (Option 000), 80 mm overall case length (Option 080), 1.0 m total cable length (Option 10), without protective armor (Option 00), and without hazardous area agency approvals (Option 00).

This eddy-current non-contact sensor is used with the 3300 XL 25 mm Proximitor Sensor and extension cable to measure large-target displacement in turbomachinery applications. It has a linear range of 12.7 mm (500 mils) and is typically used for steam turbine differential expansion (DE), thrust position, and rod-drop monitoring. Unlike armored options, this variant features a flexible FluidLoc triaxial cable without external metal armor, simplifying installation routing through tight internal conduits. While standard configurations may request the -05 multiple approvals package for hazardous areas, this specific unit is configured with the -00 no-approval option for non-hazardous locations or standard industrial installations.

Features

• Option 02 configuration includes an M30x2 metric threaded body in AISI 304 stainless steel.
• Option 000 unthreaded length specifies a fully threaded case length of 80 mm (Option 080).
• Option 10 total length includes a 1.0-meter integrated probe cable with ClickLoc coaxial connector.
• Option 00 unarmored 75-ohm FluidLoc triaxial probe cable made with perfluoroalkoxyethylene (PFA) insulation.
• Viton O-ring and rear compression seal prevent moisture ingress.
• Large-target capability provides a linear range of 12.7 mm (500 mils) with a nominal average scale factor of 0.787 V/mm (20 mV/mil).

Applications

• Industrial rotating machinery monitoring
• Steam turbine differential expansion (DE) measurements
• Thrust position and axial displacement monitoring
• Reciprocating compressor rod-drop monitoring
• Large shaft target radial or axial displacement sensing

Installation Guidelines

• Probe gap should be calibrated at approximately 7.0 mm (275 mils) or -6.5 Vdc to set the center of the linear range.
• Ensure the target size meets the minimum 61 mm (2.4 in) diameter requirement for standard calibration.
• Use the included connector protectors and disposable installation tools to prevent moisture or particulate contamination on ClickLoc connectors.
• Maintain a minimum cable bend radius of 25.4 mm (1.0 in) for unarmored FluidLoc cables.
• Threaded probe cases should be secured using the supplied locknut with safety wire holes. Torque the M30x2 threads properly to avoid damage.

Compliance and Certifications

• CE Mark (European Union compliance)
