Bently Nevada 330104-19-25-10-11-05 3300 XL 8 mm Proximity Probe

Description

330104-19-25-10-11-05 specifies a 3300 XL 8 mm armored proximity probe with metric M10 x 1 threads, featuring a 190 mm unthreaded length (Option 19), a 250 mm overall case length (Option 25), a 1.0 m total length (Option 10), an armored FluidLoc cable with a miniature coaxial ClickLoc connector and connector protector (Option 11), and CSA, ATEX, and IECEx hazardous area approvals (Option 05).

This configuration is uniquely suited for demanding machinery environments requiring metric-threaded mounting and robust mechanical shielding. The integral flexible stainless steel armor provides physical protection against impacts and abrasion, while the FluidLoc cable construction prevents fluid migration through the cable core. It pairs with a 3300 XL Proximitor sensor and a 3300 XL extension cable to form a complete 3300 XL 8 mm eddy-current proximity transducer system for machinery vibration, position, and speed monitoring.

Features

• M10 x 1 metric thread design with a 250 mm overall case length and a 190 mm unthreaded section for specific installation recess depths.
• Armored FluidLoc cable that features integral stainless steel armor for superior abrasion resistance and a specialized seal to block fluid migration.
• 1.0 meter total probe length matching 3300 XL system calibration standards.
• ClickLoc miniature coaxial connector with an integrated connector protector to shield the connection point from dirt, moisture, and mechanical stress.
• CSA, ATEX, and IECEx agency approvals certifying the probe for use in hazardous areas and intrinsically safe applications.

Applications

• Fluid-film bearing clearance measurements on steam turbines, gas turbines, compressors, pumps, and gearboxes.
• Radial shaft vibration, axial thrust position, and speed/tachometer monitoring in heavy industrial rotating machinery.
• High-moisture or oil-submerged industrial environments where FluidLoc sealing is necessary to prevent media ingress.

Installation Guidelines

When installing the M10 x 1 threaded probe, use proper case torque to prevent thread damage. The maximum rated torque for M10 x 1 standard forward-mounted cases is 22.6 N m (200 in lbf), with a recommended installation torque of 7.5 N m (66 in lbf). Observe the minimum cable bend radius of 25.4 mm (1.0 in) during cable routing. Secure the probe-to-cable connector by hand-tightening the gold ClickLoc connectors until they click. Ensure the included connector protector is fully seated over the connector joint to prevent turbine oil or moisture ingress.

Compliance and Certifications

The probe is certified under CSA, ATEX, and IECEx agency approvals (Option 05) for intrinsically safe and non-incendive installations in hazardous areas. It is designed to be used as part of a compliant 3300 XL transducer system in petroleum, chemical, and gas processing environments where explosive atmospheres are present.
