Description

The Bently Nevada 330101-00-08-10-02-05 is a high-precision, fully threaded 8 mm proximity probe belonging to the 3300 XL transducer family. Specifically configured with a 0.0-inch unthreaded length and a compact 0.8-inch case length, this variant is designed for narrow bearing housings or tight machinery spaces where housing space is extremely limited and threads must run the full length of the probe body. Operating on the eddy-current measurement principle, it provides highly reliable, non-contact displacement and shaft position data to modern machinery protection systems. Equipped with a standard (non-armored) 1.0-meter cable and a miniature coaxial ClickLoc connector, this specific configuration includes the -05 option which guarantees compliance with major international hazardous area approvals.

As a key component of the 3300 XL 8 mm proximity transducer system, this probe works in tandem with a 3300 XL extension cable and a 330180 series Proximitor sensor. It converts the relative distance between the probe tip and a rotating shaft target (typically AISI 4140 steel) into a proportional electrical signal. This signal is sent directly to monitoring racks like the Bently Nevada 3500 system to track parameters such as radial vibration, axial thrust position, speed, and keyphasor references. This direct measurement capability is crucial for implementing predictive maintenance and ensuring the mechanical integrity of heavy industrial rotating machinery.

Features

• 8 mm tip diameter engineered for reliable non-contact eddy-current displacement measurements.
• Fully threaded 3/8-24 UNF body without metal armor, allowing for deep and direct installation into bearing housings.
• Short 0.8-inch case length with 0.0-inch unthreaded length, optimized for limited-space and flush-mount machinery configurations.
• 1.0-meter (3.3 feet) standard coaxial cable with a robust gold-plated miniature ClickLoc coaxial connector.
• Certified with international CSA, ATEX, and IECEx agency approvals (-05 option) for hazardous locations.
• Constructed with a rugged polyphenylene sulfide (PPS) tip and a 303 stainless steel casing to withstand harsh, oil-saturated industrial environments.

Applications

• Steam and gas turbine shaft vibration monitoring.
• Radial vibration and axial thrust displacement measurement in high-speed compressors.
• Rotor displacement and shaft position tracking in heavy-duty industrial pumps and gearboxes.
• Continuous protection of critical rotating machinery in power generation, chemical processing, oil and gas, and wastewater treatment plants.

Installation Guidelines

• Mount the probe with the correct probe gap as specified during system calibration (typically 1.27 mm or 50 mils for the 3300 XL system).
• Ensure that the fully threaded 0.8-inch case fits without binding and does not exceed the maximum thread engagement limit of 0.563 inches to prevent case damage.
• Always secure the miniature coaxial ClickLoc connector using finger-tight torque to maintain stable electrical contact.
• Route the standard cable through proper conduits and use mounting clamps to protect it from mechanical vibration, abrasion, and oil buildup.
• Follow the recommended grounding and shielding layout to eliminate electromagnetic interference (EMI) along the critical vibration signal path.
