Description

The Bently Nevada 330101-00-36-10-02-05 is a high-performance, non-contact 8 mm Proximity Probe belonging to the industry-standard 3300 XL 8 mm Proximity Transducer System. This specific variant features a 3/8-24 UNF thread without protective armor, designed for direct installation into bearing housings or machine casings where mechanical abrasion risks are minimal. The sensor is configured with an unthreaded length of 0.0 inches (0 mm) and a 3.6-inch (91 mm) overall case length, providing a fully threaded body optimized for precise gapping and secure mounting. Equipped with a 1.0-meter (3.3-foot) total cable length and a standard miniature coaxial ClickLoc connector, this configuration provides a robust and reliable connection to 3300 XL extension cables and Proximitor sensors.

The probe utilizes eddy-current measurement principles to deliver highly accurate, non-contact static (position) and dynamic (vibration) measurements. It is widely employed in critical asset protection systems, interfacing seamlessly with 330180 series Proximitor sensors and 3500 rack monitoring channels. This configuration includes the -05 agency approval option, ensuring compliance with global CSA, ATEX, and IECEx safety standards for operation in hazardous areas.

Features

• Standard 8 mm tip diameter optimized for non-contact eddy-current displacement measurements.
• Fully threaded 3.6-inch case (0.0 in unthreaded length) allows for versatile mounting depth adjustment.
• Rugged polyphenylene sulfide (PPS) tip and stainless steel probe body built for harsh industrial environments.
• Standard 1.0-meter (3.3-foot) triaxial cable with standard miniature coaxial ClickLoc connector (without connector protector).
• Unarmored cable construction minimizes bulk in conduit runs and tight installation paths.
• Designed for permanent installation on high-speed rotating machinery, providing high-precision vibration and shaft position monitoring.

Applications

The 330101-00-36-10-02-05 probe is engineered for continuous condition monitoring and machine protection in demanding industries such as power generation, oil and gas, and chemical processing. Common applications include:

• Radial vibration and axial position measurements on steam and gas turbine shafts.
• Rotor dynamic and casing displacement monitoring in centrifugal compressors, pumps, and fans.
• Thrust bearing wear tracking and thermal expansion measurements.
• Rotational speed and phase reference (Keyphasor) detection.

Installation Guidelines

To ensure optimal performance and avoid premature transducer failure, follow these key installation practices:

• Probe Gapping: Mount the probe with the appropriate gap (typically around 1.27 mm or 50 mils) corresponding to the center of the system's linear operating range. Check the voltage output from the Proximitor sensor during calibration.
• Cable Routing: Avoid running probe cables parallel to high-voltage power lines. Always route the 75 Ohm triaxial cable through dedicated, grounded metal conduit or tray networks to minimize electromagnetic interference (EMI).
• Cable Bend Radius: Respect the minimum cable bend radius of 25.4 mm (1.0 in) to prevent damage to the internal coaxial shields.
• Tightening Torque: For standard 3300 XL gold "click" connectors, tighten finger-tight only. Do not exceed the maximum rated connector torque of 0.565 Nm (5 in-lbf). For thread installation, standard forward-mounted probes should be torqued to a recommended 11.2 Nm (100 in-lbf) and maximum 33.9 Nm (300 in-lbf).
• Environmental Protection: Protect the probe-to-extension-cable connection from direct exposure to oil, water, or steam. If exposed, use appropriate connector protectors or sealing boots rather than standard silicone tape in turbine oil environments.
