Bently Nevada 330101-00-22-10-02-05 3300 XL 8 mm Proximity Probe

Description

330101-00-22-10-02-05 is a 3300 XL 8 mm proximity probe featuring a 3/8-24 UNF thread, without protective armor. This exact configuration is defined by a 0.0 in unthreaded length (Option 00), a 2.2 in case length (Option 22), a 1.0 m total length standard cable (Option 10), a miniature coaxial ClickLoc connector (Option 02), and CSA, ATEX, and IECEx hazard area approvals (Option 05). Operating via eddy-current measurement principles, this transducer delivers non-contact shaft vibration and axial position monitoring when integrated into machinery protection systems.

Unlike sibling variants such as the armored 330102 series or the 330103 metric thread models, this specific configuration utilizes an unarmored high-temperature cable with a standard ClickLoc coaxial connection, making it ideal for installations where the cable is pre-routed inside conduit or protective bearing casings. The 1.0 m total probe length is calibrated to work directly within a standard 5-meter or 9-meter transducer system consisting of a matching extension cable and a 3300 XL Proximitor sensor.

Features

• Option 00 designates a 0.0 in unthreaded length, providing fully threaded case depth for flush-mount flexibility.
• Option 22 specifies a 2.2 in overall case length, accommodating standard mechanical housing depths.
• Option 10 dictates a 1.0 m (3.3 feet) total cable length for optimal layout configurations with extension cabling.
• Option 02 provides a standard miniature gold-plated coaxial ClickLoc connector without a connector protector.
• Option 05 includes comprehensive international hazardous area approvals from CSA, ATEX, and IECEx.
• Polyphenylene sulfide (PPS) tip is molded over a robust stainless steel probe body for high environmental sealing.
• Inherent Viton O-ring construction provides static pressure sealing between the probe tip and the external environment.

Applications

• Turbine shaft radial vibration and axial thrust position measurements on steam and gas turbines.
• Rotor dynamic displacement monitoring in high-speed compressors, fans, and centrifugal pumps.
• Permanent mechanical casing and fluid-film bearing installation on critical balance-of-plant machinery.

Installation Guidelines

Install the proximity probe in accordance with the proper probe gap calibrated for the 3300 XL monitoring system (typically set to 1.27 mm or 50 mils). Avoid overtightening the threads during case installation to prevent binding or casing distortion. Ensure that the standard coaxial cable is routed with appropriate support clamps and shielded against abrasive industrial surfaces. Keep field wiring and cable connections clean and dry, securing ClickLoc connections finger-tight to maintain signal integrity.
