Bently Nevada 330104-00-07-90-02-05 3300 XL Proximity Probe

Description

330104-00-07-90-02-05 is a 3300 XL 8 mm proximity probe configured with an M10 x 1 metric thread and integral stainless steel armor. This specific configuration features a 0 mm unthreaded length (Option 00), a 70 mm overall case length (Option 07), a 9.0-meter total system length (Option 90), a miniature coaxial ClickLoc connector without connector protector on standard cable (Option 02), and CSA, ATEX, and IECEx hazardous area approvals (Option 05).

Unlike non-armored variants like the 330103 series, the 330104 probe includes standard FEP-jacketed stainless steel armor to shield the coaxial cable against abrasion, mechanical impact, and cutting in demanding machine casings. While other configurations may utilize a shorter 1.0-meter or 5.0-meter cable or include an integrated connector protector (Option 01), this 9.0-meter variant connects directly to a 9.0-meter Proximitor sensor without requiring an intermediate extension cable, simplifying the measurement chain.

Features

• Option 00 unthreaded length with a 70 mm case length (Option 07) and metric M10 x 1 threaded steel body.
• Option 90 specifies a 9.0-meter total length, allowing direct connection to standard 9-meter Proximitor sensors.
• Option 02 miniature coaxial ClickLoc connector on standard cable provides clean signal coupling.
• Option 05 hazardous area certification package with ATEX, IECEx, and CSA approvals for Zone 0/1 environments.
• Stainless steel armor with FEP outer jacket shields the internal coaxial cable against mechanical impacts, cuts, and abrasive wear.
• Fully compatible with the 3300 XL 8 mm proximity transducer system platform.

Applications

This eddy-current proximity probe is designed for critical machinery protection and condition monitoring in heavy industrial environments. Typical applications include:

• Shaft vibration (dynamic) and axial position (static) measurements on rotating machines.
• Steam turbines, gas turbines, generators, centrifugal compressors, pumps, and electric motors.
• Fluid-film bearing monitoring in high-temperature or high-pressure environments.
• Speed and Keyphasor reference measurements in industrial rotating equipment.

Installation Guidelines

To achieve reliable monitoring performance, adhere to the following engineering installation practices:

• Thread Engagement: Do not exceed the maximum rated thread engagement of 15 mm for M10 x 1 thread cases to prevent binding during installation.
• Case Torque: Use a maximum recommended installation torque of 7.5 N-m (66 in-lbf) on the first three threads; do not exceed the absolute limit of 22.6 N-m (200 in-lbf) to protect the threaded case.
• Bend Radius: Observe a minimum cable bend radius of 25.4 mm (1.0 inch) for both the armored portion and the unarmored portion of the cable.
• Side Clearance: Maintain a minimum of 15 mm clearance around the probe tip from surrounding metal structures to avoid side-view crosstalk or signal calibration drift.
• Crosstalk Prevention: Maintain at least 40 mm spacing between adjacent 8 mm probe tips.
