Bently Nevada 330104-00-08-50-01-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded), Option 08 (80 mm overall case length), and Option 50 (5.0 m total length with armor) specify this metric threaded proximity probe configuration — 330104-00-08-50-01-05 3300 XL 8 mm Proximity Probe. Featuring an M10 x 1 thread, this configuration is supplied with integrated stainless steel armor to shield the triaxial FEP-insulated cable against mechanical wear, abrasion, and cutting fluids in harsh environments. It features a miniature coaxial ClickLoc connector with a pre-installed connector protector (Option 01) and carries CSA, ATEX, and IECEx agency approvals (Option 05) for deployment in classified hazardous areas.

This specific configuration differs from unarmored metric siblings by including flexible AISI 302 or 304 stainless steel protective armor with a protective FEP outer jacket over the entire 5-meter lead length. Because it has a total length of 5.0 meters, this probe connects directly to a 5-meter 3300 XL Proximitor sensor without requiring an intermediate extension cable, minimizing electrical connections and transmission noise in the vibration measurement loop. The fully threaded 80 mm case allows for maximum depth adjustment inside threaded mounting ports, facilitating precise sensor gapping for radial vibration, shaft position, or speed measurements.

Features

• M10 x 1 metric thread configuration with integrated flexible AISI 302 or 304 stainless steel armor and FEP outer jacket.
• Option 00 specifies a 0 mm unthreaded length, making the 80 mm probe case fully threaded for maximum mounting adjustment.
• Option 08 specifies an 80 mm overall case length to accommodate typical machine casing penetration depths.
• Option 50 provides a 5.0-meter (16.4 feet) total cable length, designed to match 5-meter Proximitor sensor systems.
• Option 01 includes a miniature coaxial ClickLoc connector with an integrated connector protector to prevent environmental contamination and moisture ingress.
• Option 05 certifies compliance with CSA, ATEX, and IECEx standards for installation in hazardous and explosive gas atmospheres.
• Polyphenylene sulfide (PPS) probe tip material molded for durability against harsh industrial lubricants and chemical exposure.
• Viton O-ring pressure seal built into the probe tip to withstand pressure differentials.

Applications

• Fluid-film bearing machinery vibration and shaft position monitoring.
• Steam turbines, gas turbines, centrifugal compressors, and electric motors in power generation and petrochemical facilities.
• Radial vibration and axial position (thrust) measurements.
• Keyphasor phase reference and speed measurement applications.
• Harsh industrial environments requiring mechanical protection for cable runs against cutting and abrasion.

Installation Guidelines

Proper installation of the metric proximity probe involves several key steps to maintain sensor calibration and prevent physical damage:

• Verify that the thread engagement length does not exceed 15 mm to avoid binding during installation in the M10 x 1 threaded mounting port.
• Set the initial probe gap (typically 1.27 mm or 50 mils) using a voltmeter to measure the Proximitor output voltage (typically -10 Vdc at the center of the linear range).
• Ensure the minimum bend radius of the armored cable is at least 25.4 mm (1.0 in) during routing to prevent internal conductor damage.
• Use the pre-installed connector protector (Option 01) to seal the probe-to-cable junction. Do not use silicone tape if the connection is exposed to turbine oil.
• Verify that the total probe length matches the Proximitor calibration; a 5.0-meter probe must connect only to a 5-meter Proximitor sensor.
