330101-00-20-15-02-05 Bently Nevada 3300 XL 8mm Probe

Product Overview

The Bently Nevada 330101-00-20-15-02-05 is a high-performance 3300 XL 8 mm Proximity Transducer Probe weighing approximately 323 g/m (11.4 oz/m), engineered for non-contact vibration and position monitoring in critical rotating machinery. Featuring a 3/8-24 UNF threaded case, 0.0-inch unthreaded length, 2.0-inch overall case length, and a 1.5-meter (4.9 feet) integrated cable with a miniature coaxial ClickLoc connector, this probe delivers accurate target displacement measurements across a 2.0 mm (80 mils) linear range. Certified for hazardous area operations under CSA, ATEX, and IECEx (Option 05), the 330101 Series integrates patented TipLoc molding and CableLoc design (75 lbf pull strength) for maximum mechanical durability in severe industrial environments.

Technical Specifications

Key Design & Construction Features

• Patented TipLoc & CableLoc Technology: Robust PPS encapsulation and bonded probe tip with 330 N (75 lbf) cable pull strength prevent physical separation in turbulent environments.
• Enhanced Mechanical Ruggedness: Thick encapsulation of the probe coil in PPS plastic coupled with 303/304 stainless steel case material provides superior abuse protection over 5 mm alternatives.
• Integrated Pressure Seal Capability: Internal Viton® O-ring construction provides differential pressure sealing between the probe tip and threaded body.
• Global Hazardous Area Compliance: Fully agency-approved (Option 05) for deployment in Zone 0/1/2 and Class I, Division 1/2 explosive atmospheres worldwide.

Installation & Field Wiring Guidelines

1. Gap Setting & Output Calibration: Set the mechanical probe gap to approximately 1.27 mm (50 mils) from the shaft target surface to establish the standard -9 Vdc baseline voltage for radial vibration monitoring.

2. Cable Connection & Routing: Lock the ClickLoc miniature coaxial connector securely to the 3300 XL extension cable. Ensure minimum bend radius requirements are met and maintain clean connector faces to avoid signal impedance changes.

3. Field Wiring to Proximitor Sensor: Connect using 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable. Maximum allowable field wiring distance between the 3300 XL Proximitor Sensor and monitor is 305 meters (1,000 feet).

Frequently Asked Questions (FAQs)

Q1: What does option -05 signify on the Bently Nevada 330101 probe?
A1: Option -05 indicates that the probe holds multiple international safety certifications, including CSA, ATEX, and IECEx approvals for hazardous environment installation.

Q2: Can the 330101-00-20-15-02-05 probe be ordered with FluidLoc cable?
A2: Yes. While option 02 specifies a standard cable, Bently Nevada offers an optional FluidLoc cable option for 3300 XL probes to prevent oil leaking through the cable interior.

Q3: Is a Certificate of Origin (COO) available for this product?
A3: Yes, a factory Certificate of Origin (COO) verifying US manufacture can be provided upon request for official documentation and export compliance.
