Description

The 330101-00-16-10-02-00 is an unarmored configuration of the Bently Nevada 3300 XL 8 mm Proximity Probe, specifically engineered with 0.0 inches of unthreaded length, a 1.6-inch overall threaded case length, a 1.0-meter total cable length, standard coaxial cabling with a miniature ClickLoc connector, and no hazardous area agency approvals. As a fundamental component of the 3300 XL 8 mm Proximity Transducer System, this non-contact sensor is designed for permanent installation in rotating machinery to measure static position and dynamic vibration. By utilizing the eddy-current operating principle, it generates a high-precision voltage signal directly proportional to the physical distance between the probe tip and the target shaft, typically made of AISI 4140 steel. This unarmored, unapproved configuration provides a cost-effective, high-performance monitoring solution for standard, non-hazardous industrial areas where external mechanical armor is not required.

Features

• Unarmored 3/8-24 UNF Body: Features a fully threaded 1.6-inch stainless steel case (0.0 inches unthreaded) that allows direct mounting into machine housings and bearing caps without external physical armor.
• Standard 1.0 Meter Cable: Supplied with a 1.0-meter (3.3-foot) standard coaxial cable, making it ideal for clean routing into intermediate connection boxes before interfacing with an extension cable.
• ClickLoc Miniature Connector: Equipped with a miniature coaxial ClickLoc connector to ensure secure, low-loss, and vibration-resistant signal coupling in heavy rotating machinery.
• Eddy-Current Principle: Delivers precise non-contact displacement measurements with a nominal Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil) when paired with compatible 3300 XL components.
• Rugged Tip Construction: The 8 mm probe tip is molded from high-performance polyphenylene sulfide (PPS) plastic and chemically sealed against moisture, steam, and industrial oil environments.

Applications

• Continuous radial shaft vibration monitoring in utility steam and gas turbine generators.
• Thrust (axial) position and displacement measurements in high-speed centrifugal compressors and industrial turbo-expanders.
• Rotor dynamic profiling and bearing clearance diagnostics in large petrochemical pumps, industrial fans, and gearboxes.
• General machinery protection and condition monitoring within standard, non-hazardous industrial facilities.

Installation Guidelines

To ensure optimal measurement performance and long-term mechanical reliability, the following engineering installation practices are recommended:

• Thread Verification: Clean and inspect the internal 3/8-24 UNF threaded mounting hole on the machine casing. Because this SKU has 0.0 inches of unthreaded length, confirm that the housing is fully threaded to safely receive the 1.6-inch case.
• Probe Gap Setting: Position the probe with the appropriate gap relative to the shaft target. A standard baseline is 1.27 mm (50 mils), which corresponds to the midpoint voltage of system calibration (nominally -10 Vdc output at the Proximitor sensor).
• Cable Protection: Since this probe uses a standard unarmored cable, route the coaxial run through dedicated rigid or flexible conduit to prevent accidental tearing, pinching, or exposure to excessive mechanical stress.
• Shielding and Grounding: Ensure the coaxial cable shield is electrically isolated at the probe mounting end and single-point grounded at the Proximitor sensor or instrument rack to prevent electromagnetic interference and ground loop noise.
• Bending Radius: Maintain a minimum bending radius of 25.4 mm (1.0 inch) for the standard coaxial cable during routing to avoid signal attenuation or physical damage to the internal conductors.
