Bently Nevada 330105-02-12-90-02-00 3300 XL 8mm Reverse Mount Proximity Probe

Description

Designed for non-contacting vibration and displacement measurements in critical rotating machinery, the Bently Nevada 330105-02-12-90-02-00 serves as a key sensor component within the 3300 XL 8mm Proximity Transducer System. This reverse mount configuration features a 3/8-24 UNF thread and is engineered for specialized installation environments where standard forward-mounting is impractical. The system operates on eddy-current principles to measure static (gap) and dynamic (vibration) distances between the probe tip and the target conductive surface.

The integrated coaxial cable terminates in a specialized coaxial connector, ensuring excellent signal transmission stability back to the Proximitor sensor. With its robust mechanical housing and advanced sealing, this probe is capable of continuous operation in demanding industrial environments, including exposure to lubricating fluids and extreme temperatures. It interfaces seamlessly with machinery protection monitors and diagnostic systems to track shaft vibration, radial position, and axial thrust in heavy industrial assets.

Features

• Reverse Mount Design: Enables installation from the reverse side of machine housings or mounting brackets.
• ClickLoc Coaxial Connector: Features a gold-plated, corrosion-resistant miniature connection mechanism that prevents accidental disconnection.
• 9.0-Meter Total Length: Eliminates the need for a separate extension cable when paired directly with a matching 9.0-meter Proximitor sensor.
• High-Quality Construction: Utilizes polyphenylene sulfide (PPS) tip material and a stainless steel probe body for superior durability against chemicals and high pressures.

Applications

• Steam and gas turbine shaft vibration and axial position monitoring.
• Centrifugal and axial compressor health tracking.
• Industrial gearbox shaft displacement measurements.
• Boiler feed pump and cooling water pump shaft relative movement monitoring.

Technical Specifications

Installation Guidelines

• Mounting Torque: Do not exceed the maximum torque specification of 10.7 N-m (95 in-lb) when securing the 3/8-24 UNF threads.
• Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the coaxial extension cable to prevent structural damage and signal attenuation.
• Connector Care: Ensure that the ClickLoc coaxial connectors are clean, dry, and free of oil before mating. Align the connectors and push firmly until the locking click is felt.
• Sleeve Installation: When using reverse-mount sleeves, verify that the probe tip does not contact the target during sleeve insertion to prevent physical impact damage to the PPS tip.
