Description

Designed for demanding industrial rotating machinery environments, the Bently Nevada 330702-00-26-10-11-CN proximity probe provides non-contacting displacement and vibration measurements. As a core component of the 3300 XL 11 mm Transducer System, this probe offers a wider linear range than standard 8 mm probes, making it ideal for applications requiring extended measurement spans or when mounting constraints necessitate a larger tip diameter.

This specific configuration is built with a completely unthreaded length and a 2.6-inch overall case length to accommodate internal mounting configurations. Equipped with a FluidLoc cable, the probe prevents oil or other process fluids from leaking out of the machine through the cable interior. Signal transmission is secured via a miniature coaxial ClickLoc connector paired with a rugged connector protector, ensuring reliable operation under high-vibration conditions.

Features

• Enhanced Linear Range: 11 mm probe tip design delivers broader measuring range capabilities than standard 8 mm options.
• FluidLoc Cable Technology: Prevents process fluids and moisture from wicking through the inner core of the cable.
• Rugged Material Construction: High-performance Polyphenylene sulfide (PPS) tip paired with an AISI 304 stainless steel case for extreme durability.
• ClickLoc Coaxial Connection: Includes a miniature coaxial ClickLoc connector and integrated connector protector to resist vibration-induced disconnects.
• High-Temperature Integrity: Built to withstand operating and storage environments from -51 degC to +177 degC.

Applications

• Steam and gas turbine shaft vibration and position monitoring.
• Hydroelectric generator thrust and radial displacement tracking.
• Large industrial compressors, pumps, and fans in petrochemical processing.
• Machinery protection and condition monitoring in power generation plants.

Installation Guidelines

• Vibration Clearance: Ensure the probe tip has adequate radial clearance from surrounding metal to prevent lateral interference or false readings.
• Torque Limits: Follow nominal torque specifications for 11 mm thread sizes to avoid shearing or damaging the AISI 304 case during installation.
• Cable Routing: Protect coaxial extensions from sharp bends or physical pinching. Maintain the minimum recommended bend radius for coaxial cabling.
• Grounding: Ensure the system shield is properly terminated at the Proximitor sensor housing and isolated from the machine ground.
