Bently Nevada 330101-00-60-10-02-CN Probe | New

Product Overview

The Bently Nevada 330101-00-60-10-02-CN is a heavy-duty, extended-reach 3300 XL 8 mm proximity probe engineered for critical machinery protection, fluid film bearing tracking, and relative shaft vibration monitoring. Made in the U.S.A., this premium eddy current sensor features a standard 3/8-24 UNF fractional thread configuration, designed completely without protective armor. 

Core Technical Advantages

Patented TipLoc™ and CableLoc™ Engineering

This sensor incorporates a patented TipLoc molding method that forms an exceptionally secure mechanical bond between the Polyphenylene Sulfide (PPS) probe tip and the stainless steel barrel. Combined with the advanced CableLoc anchoring mechanism, the coaxial lead withstands up to 330 N (75 lbf) of pull strength to prevent accidental strain-induced failures during routine field servicing.

Ruggedized 8 mm Shell Architecture

Featuring a thicker plastic encapsulation around the internal sensing coil, the 8 mm tip layout provides robust protection against particle bombardment. The larger diameter AISI 303/304 stainless steel casing offers increased resistance against bending forces and physical abuse, making it the highly recommended choice for deep-bore machine inserts.

Superior Moisture and Humidity Immunity

Tested in absolute compliance with IEC standard 68-2-3, the 3300 XL probe exhibits less than a 3% change in Average Scale Factor (ASF) even when exposed to 93% relative humidity for up to 56 days. This provides high measurement reliability and drift-free voltage returns in steam-saturated environments.

Technical Specifications

Installation and Maintenance

Mechanical Gapping and Positioning

When deploying the probe for radial vibration monitoring, field engineering crews should adjust the mechanical gap to a recommended setting of 1.27 mm (50 mils). This physical alignment maps the sensor perfectly to the center point of its 2.0 mm linear monitoring envelope, which translates directly to a baseline electrical output of -9 Vdc.

Field Wiring Infrastructure

Field connections accept 0.2 to 1.5 mm² (16 to 24 AWG) wiring networks. It is highly recommended to employ a three-conductor shielded triad cable layout paired with tinned field wiring. Ensure the maximum line length between the 3300 XL Proximitor Sensor and the monitoring panel does not exceed 305 meters (1,000 feet) to prevent high-frequency attenuation.

Thermal Conditions and Seal Preservation

The standard probe structure operates within a safe thermal envelope of -52°C to +177°C (-62°F to +350°F). However, plant operators must note that exposing the assembly to freezing micro-climates below -34°C (-30°F) can result in premature structural contraction and degradation of the integrated Viton pressure seal.

Engineering Advantages

Excellent Linearity Tracking

The 1-meter sensor loop guarantees a Deviation from Best Fit Straight Line (DSL) of less than ±0.025 mm (±1 mil) during normal operations spanning from 0°C to +45°C. This tight calculation envelope yields clean, reproducible displacement logs for high-reliability control panels.

Viton® Leakage Protection

Every 3300 XL 8 mm probe features an integrated Viton O-ring contextually rated to seal differential pressures across the probe tip and outer metal case. For extreme oil pressure environments or custom containment certification, specialized pressure validation can be arranged before plant installation.

Standard Internal Resistance

With a factory-calibrated nominal DC resistance tracking at 7.59 ± 0.50 ohms from the inner conductor to the outer shield, verification teams can execute rapid field health assessments using standard digital multimeters right at the junction box.

Technical FAQs

Q1: What is the total linear range of the Bently Nevada 3300 XL 8 mm probe?

A1: The linear range is 2 mm (80 mils). This monitoring window starts at approximately 0.25 mm (10 mils) from the target face and extends to 2.3 mm (90 mils), providing an electrical signal output ranging from roughly -1 to -17 Vdc.

Q2: What are the primary physical dimensions of the 330101-00-60-10-02-CN assembly?

A2: This specialized model features a fully threaded barrel layout with a 0.0-inch unthreaded length and an extended 6.0-inch overall stainless steel case length, matching deep-seated mounting brackets with a 3/8-24 UNF thread profile.

Q3: How much weight does the coaxial probe cable add to the installation track?

A3: The unarmored 75-ohm coaxial probe cable has a calibrated structural mass specification of 323 grams per meter (11.4 ounces per meter), maintaining a lightweight yet physically stable routing profile.
