Product Overview

The Bently Nevada 330104-00-18-10-01-05 3300 XL 8 mm Proximity Transducer delivers unmatched dynamic accuracy for machine health deployment. This metric-threaded eddy current hardware tracks critical machine indicators such as radial shaft vibration, axial thrust position, and oil film clearance on heavy rotating infrastructure. It transmits clean, continuous analog signals directly into Bently Nevada 3500 rack monitors and Distributed Control Systems (DCS), executing the primary input acquisition for plant-wide Emergency Shutdown (ESD) loops. By converting microvolt-level physical displacements into a highly linear voltage output scale factor, it enables instrumentation specialists to isolate sudden rotor anomalies before catastrophic failures occur. The advanced internal coil geometry maintains exceptional thermal performance, suppressing measurement drift inside heavy process compressors, steam turbine packages, and high-velocity utility pumps.

Structural Part Option Decoder

330104: 3300 XL 8 mm Proximity Probe with M10 x 1 Metric Thread

This core model designator specifies an 8 mm tip diameter sensor body engineered with standard M10 x 1 metric structural thread profiles for specialized housing ports.

Unthreaded Length Designation: -00

This selection indicates a 0 mm unthreaded housing option. Continuous metric threads run along the entirety of the steel casing shell, providing complete mechanical adjustment depth within the mounting bore.

Overall Case Length Designation: -18

This parameter establishes an 180 mm overall case length, dictating the physical structural immersion depth of the steel probe casing inside the machine bearing block.

Total Cable Length Parameter: -10

This suffix dictates a 1.0-meter (3.3 feet) integrated cable line length, measured from the encapsulated sensor face directly to the end of the coaxial coupling.

Connector Option Profile: -01

This choice confirms the attachment of a miniature coaxial Click-Loc plug with a miniature coaxial cable profile, ensuring low-loss signal propagation across the monitoring loop.

Regulatory Approval Type: -05

This suffix designates multiple global hazardous area certifications, legally validating the intrinsic safety and explosion-proof parameters of the sensor for deployment in ATEX, IECEx, and CSA regulated zones.

Mechanical and Electrical Attributes

On-Site Deployment Rules

Target Gap Voltage Optimization

Thread the M10 sensor shell into the machine bearing bracket while monitoring the live DC voltage across the terminals of the matched 3300 XL Proximitor sensor. Manually turn the probe body within the port hole until your digital voltmeter displays exactly -10.0 VDC, verifying that the target shaft face rests perfectly at the center of the calibrated linear measurement window.

Cable Geometry Routing Limits

Enforce a rigid minimum cable bend radius limitation of 25.4 mm (1.0 inch) along the entire layout path to avoid crushing the internal coaxial shielding matrix. Route all low-voltage transducer cables through independent, grounded iron conduits to isolate the raw signals from stray electromagnetic fields emitted by high-voltage generator leads or heavy switching panels.

Environmental Joint Protection

Always isolate the intermediate Click-Loc connector junction point linking the integrated probe line to the system extension cable inside a sealed terminal box. Apply proper liquid-tight industrial cable glands to eliminate oil ingress and moisture condensation, preserving infinite loop insulation resistance.

Critical Environment Endurance

Caustic Media Defenses

The high-grade 303 stainless steel frame and vacuum-molded PPS tip face provide complete immunity against aggressive synthetic lubricants, process steam, and hot moisture. Specialized manufacturing layers stop fluid migration into the internal sensing coils during rapid machine startup thermal cycles, suppressing signal distortion or voltage spiking.

Distributed Control Synergy

This proximity probe generates the pure, high-frequency analog waveforms required by advanced Turbine Supervisory Instrumentation (TSI) diagnostics. It transmits uncompromised raw tracking vectors into regional processing modules, integrating flawlessly with Honeywell Experion PKS architectures for real-time orbit plotting, shaft centerline tracking, and oil film diagnostics.

Engineering Support FAQs

Q1: What is the mechanical difference between a 330104 metric probe and a standard 330101 probe?

A1: The main difference is the outer casing thread type. The 330101 probe utilizes English imperial threads (3/8-24 UNF), while this 330104 probe uses metric threads (M10 x 1). Always check the tapped profile of your machine's bearing housing port before installation to avoid serious cross-threading damage.

Q2: How does the -05 suffix impact deployment in hazardous processing areas?

A2: The -05 suffix indicates that this probe carries multiple global hazardous area certifications, including ATEX, IECEx, and CSA approvals. It legally validates the intrinsic safety and explosion-proof parameters of the sensor, allowing safe deployment inside Class I, Division 1 or Zone 0 explosive atmospheres when wired through a certified safety barrier.

Q3: Can I connect this 1.0-meter integrated probe line directly to a 9.0-meter extension cable?

A3: No, doing so will throw off the total electrical balancing of the circuit. Bently Nevada 3300 XL 8 mm proximity systems operate on strict total loop lengths of either 5.0 meters or 9.0 meters. Since this probe has an integrated 1.0-meter cable, you must use a 4.0-meter or 8.0-meter extension cable to complete the calibrated circuit correctly.
